Título: Prospective production of fructose and single cell protein from date palm waste
Fonte: Electron. j. biotechnol;48:46-52, nov. 2020. graf, tab.
Idioma: en.
Projeto: King Saud University.
Resumo: BACKGROUND: Fructose and single cell protein are important products for the food market. Abundant amounts of low-grade dates worldwide are annually wasted. In this study, highly concentrated fructose syrups and single cell protein were obtained through selective fermentation of date extracts by Saccharomyces cerevisiae. RESULTS: The effect of air flow (0.1, 0.5, 0.75, 1, 1.25 and 1.5 vvm) and pH (4.5, 4.8, 5, 5.3 and 5.6) was investigated. Higher air flow led to lower fructose yield. The optimum cell mass production of 10 g/L was achieved at air flow of 1.25 vvm with the fructose yield of 91%. Similar cell mass production was obtained in the range pH of 5.0­5.6, while less cell mass was obtained at pH less than 5. Controlling the pH at 4.5, 5.0 and 5.3 failed to improve the production of cell mass which were 5.6, 5.9 and 5.4 g/L respectively; however, better fructose yield was obtained. CONCLUSIONS: Extension of the modified Gompertz enabled excellent predictions of the cell mass, fructose production and fructose fraction. The proposed model was also successfully validated against data from literatures. Thus, the model will be useful for wide application of biological processes.

Título: Effect of Agitation on Anaerobic Co-Digestion of Swine Manure and Food Waste
Fonte: Braz. arch. biol. technol;64:e21200102, 2021. tab, graf.
Idioma: en.
Resumo: Abstract The synergism of food waste associated with swine manure can provide an increase in biogas production, besides promoting greater stability in the anaerobic co-digestion process. To verify this effect, co-digestion tests were performed in two reactors, one with agitation, and the other without agitation. In both systems, gasometers were used to measure biogas production in an experiment lasting two hydraulic retention times (HRT). On each feeding day, the temperatures of the ambient and of the effluent taken from the reactors were measured, and samples of the food waste and effluent were collected to perform analysis of pH, total solids (TS), volatile solids (VS), fixed solids (FS), volatile acidity (AV), and total alkalinity (TA). In addition, the chemical oxygen demand (COD) was determined every five days, and gas composition was determined at the beginning of the second HRT. As important results, in both reactors a decrease in pH was verified due to the weakening of the buffer effect of the medium. This was due to the low alkalinity found in the food waste, causing an increase in acidity in the contents of the reactors. The volume of biogas produced was higher in the reactor with agitation, which meant an increased efficiency of the process. Finally, a low methane content was verified through chromatographic analyses, indicating a reduction in the activity of the microorganisms present in the medium. Thus, it is concluded that agitation linked to anaerobic co-digestion of swine manure with food waste exerted a positive effect on biogas production.

Idioma: pt.
Resumo: Sialolitos são estruturas calcificadas, que se desenvolvem no interior do sistema ductal salivar, em decorrência da deposição de sais de cálcio ao redor de um acúmulo de restos orgânicos no lúmen do ducto glandular. Acometem, com mais assiduidade, a glândula submandibular e são a causa mais comum de inflamações agudas ou crônicas nas glândulas salivares maiores. Manifestam-se, com maior frequência, em indivíduos adultos de meia-idade, e os sinais e sintomas mais comuns são a dor e a tumefação local. Podem ser evidenciados por radiografias convencionais, tomografia computadorizada, ressonância magnética, ultrassonografia, cintilografia, sialoendoscopia e sialografia. O tratamento inclui a eliminação espontânea mediante orientações ou uso de medicamentos, ou a remoção cirúrgica do sialolito, sendo necessária, em alguns casos, a exérese da própria glândula. Este trabalho tem como objetivo relatar o caso clínico do paciente S.L.M, 44 anos de idade, sexo feminino, caucasiana, atendida na clínica de Cirurgia Bucal da Universidade Federal Fluminense, apresentando um sialolito no sistema ductal da glândula submandibular do lado esquerdo. A paciente foi submetida à remoção cirúrgica do sialolito sob anestesia local, sem maiores intercorrências... (AU)

Sialolites are calcified structures that develop inside the salivary ductal system, due to the deposition of calcium salts around an accumulation of organic remains in the lumen of the glandular duct. They have a more frequent involvement of the submandibular gland and are the most common cause of acute or chronic inflammation in the major salivary glands. They occur more frequently in middle-aged adult patients and the most common signs and symptoms are local pain and swelling. They can be evidenced by conventional radiography, computed tomography, MRI, ultrasonography, scintigraphy, sialoendoscopy and sialography. Treatment includes spontaneous elimination, from guidelines or use of medications, or surgical removal of sialolite, in some cases, the excision of the gland itself. This study aims to report the clinical case of the patient S.L.M, 44 years old, female, Caucasian, attended at the Oral Surgery Clinic of the Federal Fluminense University, presenting a sialolite in the ductal system of the left submandibular gland. The patient was submitted to surgical removal of the sialolite, under local anesthesia, without major intercurrences... (AU)

Idioma: es.
Resumo: El cultivo de los hongos del género Pleurotus sp. es de importancia debido a que producen proteínas de alta calidad sobre un sustrato que consiste en materiales de desecho de carácter lignocelulósico. El objetivo fue evaluar el uso de residuos agrícolas: cáscara de papa, plátano y bagazo de caña, como una alternativa proteica en el corregimiento de Llacuanas municipio de Almaguer (Cauca). El diseño experimental fue completamente al azar, con cuatro tratamientos y cinco repeticiones por tratamiento, donde se tuvieron en cuenta variables físicas (color y textura); y de producción (Colonización, peso y diámetro). El análisis de varianza mostro diferencias estadísticas significativas para peso y diámetro; y la prueba post hoc de Duncan, evidenció que los mejores tratamientos fueron 1 y 2 (Bagazo de caña, cascara de plátano, salvado de maíz y cal agrícola), sustratos constituidos por carbohidratos estructurales que favorecen el desarrollo del hongo.

The cultivation of fungi of the genus Pleurotus sp. is of importance because they produce high quality protein on a substrate consisting of lignocellulosic IN waste materials. The objective was to evaluate the use of agricultural residues: potato peels, banana and sugarcane pulp, as an alternative protein in the village of Llacuanas, municipality of Almaguer (Cauca). The experimental design was completely randomized with four treatments and five replicates per treatment in which physical variables (color and texture) and production (Colonization, weight and diameter) were considered. The analysis of variance showed statistically significant differences for weight and diameter; the Duncan post hoc test showed that the best treatments were 1 and 2 (sugarcane pulp, banana peel, corn bran and agricultural lime), substrates consisting of structural carbohydrates that promote the growth of the mushroom.

Título: Evaluación de las propiedades físicas y químicas de residuos sólidos orgánicos a emplearse en la elaboración de papel / Evaluation of the physical and chemical properties of organic solid waste for use in the preparation of paper
Fonte: Rev. luna azul;(43):499-517, jul.-dic. 2016. ilus, tab.
Idioma: es.
Resumo: La producción de papel está soportada principalmente en la madera debido a su alto contenido de celulosa. Sin embargo, actualmente se buscan fuentes alternativas que desestimulen el uso de este recurso favoreciendo la protección de los bosques. La celulosa también está presente en las especies vegetales que hacen parte del consumo humano y, por lo tanto, los residuos orgánicos podrían convertirse en materia prima para la fabricación de papel. En Colombia más del 60% de los residuos que se generan son de carácter orgánico y muy pocos se están aprovechando. Esta investigación se centró en evaluar el contenido de celulosa en diferentes residuos sólidos orgánicos. También, se evaluaron otras propiedades químicas como contenido de hemicelulosa y lignina, y propiedades físicas como densidad, contenido de humedad, entre otros, ya que estas propiedades condicionan los procesos de producción de papel y son importantes para conocer la viabilidad de uso y la estrategia de la extracción de la celulosa. 21 residuos sólidos fueron analizados a través de pruebas de laboratorio basadas en las normas ASTM y TAPPI y se encontró que 9 de estos tienen un alto contenido de celulosa. Tomando en cuenta todos los demás análisis se concluyó que varios residuos tienen alto potencial para ser usados en la producción de papel. El uso de residuos sólidos, además de ser una solución que promueve la protección de los bosques, se puede convertir en una alternativa para el manejo de residuos sólidos en Colombia.

Paper production is supported mainly by the wood due to its high content of cellulose. However, alternative sources that discourage the use of this resource and promoteprotection of forests are currently sough. The cellulose is also present in plants that are part of human consumption and therefore organic waste could become raw material for papermaking. In Colombia more than 60% of waste that is generated is organic and very few are reused. This research focused on evaluating the content of cellulose in several solid organic waste. Other chemical properties as hemicellulose and lignin content, and physical properties such as density, humidity, among others, were also evaluated because these properties determine the process of paper production and are important to know the feasibility to use and the strategy to extract the cellulose. 21 solid waste were analyzed by laboratory tests based on the ASTM and TAPPI standards and it was found that 9 of these solids have high cellulose content. Taking in account all the other analyses, we concluded that various solid residues have high potential to be used in the production of paper. The use of solid waste could be a solution that promotes the protection of forests and it would become in an alternative for solid waste management in Colombia.

Idioma: es.
Resumo: En esta investigación aplicada, desarrollada por la Escuela de Ingeniería Química y la Escuela de Tecnología en Alimentos, se presentan alternativas para utilizar cáscaras de vegetales como materia prima para la elaboración de productos alimenticios. Para lograrlo se utilizaron cáscaras de papa, plátano y restos de repollo de la Cafetería Escuela de ITCA ­ FEPADE. Estos fueron procesados para transformarlos en polvos, a los cuales se les practicaron análisis físico químicos, bromatológicos y microbiológicos. Se utilizaron métodos gravimétricos e instrumentales, espectrofotometría de absorción atómica y molecular. Resultado de esos análisis se determinó que: los polvos son productos inocuos, que su tamaño de partícula es mayor a las 212 micras (tamices acoplados). Además, el análisis reveló que el polvo con mayor aporte nutricional es el proveniente de la cáscara de plátano con contenido de carbohidratos (23.74%), hierro (63.83 mg), potasio (47.82 mg) y calcio (54.03 mg). Del polvo de cáscara de papa se destaca su contenido de hierro (110.58 mg). Los polvos se utilizaron como materia prima combinada con harinas de trigo, sorgo y maíz para preparar productos alimenticios. Se evaluaron sus características sensoriales a través de un grupo focal. También, como producto de esta investigación, se desarrolló una guía de manipulación de los restos vegetales y un recetario con información nutricional de los productos elaborados. Se concluyó que los polvos obtenidos son aptos para ser utilizados como materia prima de productos alimenticios y se recomienda particularmente el polvo obtenido de la cáscara de plátano por su riqueza nutricional en cuanto a contenido de carbohidratos, hierro y potasio.

In this applied research developed by the School of Chemical Engineering and the School of Food Technology, alternatives are presented to use vegetable husks as raw material for the elaboration of food products. In order to achieve this, potato and banana peels, and cabbage remains from Cafeteria Escuela ITCA-FEPADE were used. These were processed to transform them into powders, which were subjected to physical, chemical, bromatological and microbiological analysis. Gravimetric and instrumental methods, atomic and molecular absorption spectrophotometry were used. The result of these analysis was that powders are innocuous products which particle size is greater than 212 microns (coupled sieves). In addition, the analysis revealed that the powder with the greatest nutritional contribution comes from banana due to his carbohydrate content (23.74%), iron (63.83 mg), potassium (47.82 mg) and calcium (54.03 mg). From potato peel powder, it stands out its iron content (110.58 mg). The powders were used as a raw material combined with wheat, sorghum and corn flours to prepare food products. Their sensory characteristics were evaluated through a focal group. Also, as product of this research, a guide for the manipulation of vegetable remains and a recipes book with nutritional information of the produced products were developed. It was concluded that the powders obtained are suitable for using as raw material in food preparing and the powder obtained from the banana peel is particularly recommended for its nutritional richness in terms of carbohydrate, iron and potassium content.

Título: Casos de dengue e coleta de lixo urbano: um estudo na Cidade do Recife, Brasil / Cases of dengue and urban waste collection: a study in the City of Recife
Fonte: Ciênc. Saúde Colet;24(3):1075-1082, mar. 2019. tab.
Idioma: pt.
Resumo: Resumo O objetivo desse estudo foi identificar quais categorias de lixo urbano apresentam associação com casos de dengue e, em seguida, avaliar o impacto da coleta de lixo sobre os casos da doença na cidade do Recife. Foram utilizados dados da pesagem categorizada de lixo, juntamente com os casos confirmados de dengue no município. Os dados foram analisados através do coeficiente de correlação de Pearson para as treze categorias de lixo, seguido pela Regressão Linear Multivariada, selecionando as variáveis pelo método de "stepwise". Identificou-se a existência de correlação negativa entre o total de casos de dengue em sete categorias: lixo domiciliar (r = -0,835), resíduos diferenciados (r = -0,835), resíduos de operações especiais (r = -0,711), entulhos (r = -0,687), coleta seletiva (r = -0,425) e pneus (r = -0,423). O modelo de regressão foi capaz de explicar 75% da variação, apontando que um incremento de 1.000 toneladas na coleta de lixo doméstico proporciona uma redução de 0,032 casos de dengue enquanto que o mesmo incremento na coleta de pneus é capaz de reduzir 0,465 casos da doença. Os resultados demonstram que a coleta de lixo possui um forte impacto negativo nos casos de dengue e podem ser adotados como estratégia de prevenção pelos governos municipais.

Abstract The scope of this study was to identify which categories of urban waste are associated with cases of dengue and to evaluate the impact of garbage collection on dengue infection in the City of Recife (Brazil). Data from categorized waste weighing and the confirmed cases of dengue in the city were used. The data were analyzed using Pearson's correlation coefficient for the 13 categories of urban garbage, followed by Multivariate Linear Regression, selecting the variables by the stepwise method. A negative correlation between dengue infections in seven categories was identified: household garbage (r = -0.835), differentiated residues (r = -0.835), special operations residues (r = -0.711), building rubble (r = -0.687), selective waste collection (r = -0.425) and tires (r = -0.423). The regression model was able to explain 75% of the variation, indicating that an increase of 1,000 tons in household garbage collection provides a decrease of 0.032 in cases of dengue, while the same increase in tire collection esults in a decrease of 0.465. The results show that garbage collection has a strong negative impact on dengue cases and can be adopted as a prevention strategy by municipal governments.

Título: Assessment of pectinase-producing fungi isolated from soil and the use of orange waste as a substrate for pectinase production
Fonte: Rev. ciênc. farm. básica apl;40, 01/01/2019. ilus, tab.
Idioma: en.
Resumo: Pectinases are important enzymes not only for their potential applications in different industries such animal feed, agricultural, textile, beverage, food processing, oil extraction, etc. Ten fungal species were isolated from the soil and screened for production of pectinase enzyme by using the pectin agar medium. Pectinolytic enzymes synthesis were attained at a temperature of 30 °C and activities were determined after a seven-days culture of Aspergillus sp. 391 and Aspergillus sp. 031, in a basic medium containing 2% citrus pectin and as the sole carbon source. The extract enzymatic showed an optimum activity for exo-polygalacturonase (PG) and pectin lyase (PNL) against galacturonic acid and pectin at pH 4.5 and 5.5, respectively. There were variations in PG and PNL enzymes levels produced in culture filtrates obtained of Aspergillus sp. 391 with addition of citrus waste (2.0 and 4.0 % w/v) to the medium. Maximum activity for PNL activity was observed in the medium containing 5% pectin or 4% citrus waste, as sole carbon source, after 7 days of growth. The results showed that the isolate Aspergillus sp. 391 is a promising for pectinolytic enzymes production at the industrial level.(AU)

Título: Residuos agroindustriales con potencial para la producción de metano mediante la digestión anaerobia / Agroindustrial wastes methanization and bacterial composition in anaerobic digestion
Fonte: Rev. argent. microbiol;47(3):229-235, set. 2015. ilus, tab.
Idioma: es.
Resumo: Las toneladas de residuos orgánicos que se generan anualmente en la agroindustria pueden aprovecharse como materia prima para la producción de metano. Para que los residuos orgánicos se puedan convertir a metano a gran escala, es importante que previamente se realicen sobre ellos pruebas de biodegradabilidad; un parámetro importante que conviene establecer es su potencial bioquímico de metano. En el presente trabajo se estudió la biodegradabilidad, la producción de metano y el comportamiento de poblaciones de eubacterias y arqueobacterias durante la digestión anaerobia de residuos de plátano, mango y papaya provenientes de la agroindustria, adicionando un inóculo microbiano. Los residuos de mango y plátano tenían mayor contenido de materia orgánica (94 y 75 %, respectivamente) que el residuo de papaya con base en su relación sólidos volátiles/sólidos totales. Después de 63 días de tratamiento, la mayor producción de metano se observó en la digestión anaerobia del residuo de plátano: 63,89 ml de metano por g de demanda química de oxígeno del residuo. Los resultados del potencial bioquímico de metano demostraron que el residuo de plátano tiene el mejor potencial para ser usado como materia prima en la producción de metano. A través de un análisis por PCR-DGGE con oligonucleótidos específicos se logró evaluar el tamaño y la composición de las poblaciones de eubacterias y arqueobacterias presentes en la digestión anaerobia de residuos agroindustriales a lo largo del proceso.

The tons of organic waste that are annually generated by agro-industry, can be used as raw material for methane production. For this reason, it is important to previously perform biodegradability tests to organic wastes for their full scale methanization. This paper addresses biodegradability, methane production and the behavior of populations of eubacteria and archaeabacteria during anaerobic digestion of banana, mango and papaya agroindustrial wastes. Mango and banana wastes had higher organic matter content than papaya in terms of their volatile solids and total solid rate (94 and 75 % respectively). After 63 days of treatment, the highest methane production was observed in banana waste anaerobic digestion: 63.89 ml CH4/per gram of chemical oxygen demand of the waste. In the PCR-DGGE molecular analysis, different genomic footprints with oligonucleotides for eubacteria and archeobacteria were found. Biochemical methane potential results proved that banana wastes have the best potential to be used as raw material for methane production. The result of a PCR- DGGE analysis using specific oligonucleotides enabled to identify the behavior of populations of eubacteria and archaeabacteria present during the anaerobic digestion of agroindustrial wastes throughout the process.
