Título: Carotenoid production in sugarcane juice and synthetic media supplemented with nutrients by Rhodotorula rubra l02
Fonte: Braz. j. microbiol;49(4):872-878, Oct.-Dec. 2018. graf.
Idioma: en.
Resumo: ABSTRACT In order for the use of biological carotenoids to become feasible, it is necessary to have adequate low cost sources and improved methods of cultivation. The aim of this study was to evaluate the effect of supplementation with nitrogen, phosphorus, zinc, and magnesium, on the biomass and carotenoid volumetric production by yeast Rhodotorula rubra L02 using a complex medium (sugarcane juice) and synthetic media (sucrose and maltose) as substrates. The experimental design used for each substrate was randomized in blocks with 16 treatments and 3 repetitions. The treatments were compound for 15 different combinations of nutrients (N; Mg; Zn; P, N + Mg; N + Zn; N + P; Mg + Zn; Mg + P; Zn + P; N + P + Zn; N + P + Mg; N + Zn + Mg; P + Zn + Mg; N + Zn + Mg + P) alone and combined, and a control. The results were submitted to analysis of variance and Tukey test at 5% significance level. Among the treatments evaluated, the highest production of dry biomass, with both maltose and sucrose, was observed for Mg (1.60 g/L and 1.94 g/L, respectively). Additionally, another treatment that stood out in terms of biomass production was the control treatment with maltose (1.54 g/L). After the incubation time, killer activity was not observed since there was no formation of inhibition halo around the L02 yeast.

Resumo: Abstract Extraction of compounds from microalgae requires cell disruption as a pretreatment to increase extraction yield. Botryococcus braunii is a microalga with a significant content of carotenoids and other antioxidant compounds, such as chlorophylls. Cell disruption of B. braunii using CO2 rapid depressurization was studied as a pretreatment for the extraction of carotenoid and chlorophyll pigments. We studied the effect of temperature (21–49 °C) and pressure (6–13 MPa) during static compression on pigment recovery with supercritical CO2 at 40 °C, 30 MPa and solvent flow of 4.7 L NPT/min. Within the experimental region, the extraction yield of carotenoids and chlorophylls increased by 2.4- and 2.2-fold respectively. Static compression conditions of high pressure and low temperature increased the extraction of carotenoids and especially chlorophylls. We selected 21 °C and 13 MPa as the cell disruption condition, which produced 1.91 g/kg d.s. of carotenoids and 14.03 mg/kg d.s. of chlorophylls. Pretreated microalga gave a 10-fold higher chlorophyll extraction yield compared to the untreated sample. While for carotenoids and tocopherols were 1.25 and 1.14-fold higher, respectively. Additionally, antioxidant activity of pretreated microalga (33.22 mmol TE/kg oil) was significantly higher than the value for the untreated samples (29.11 mmol TE/kg oil) (p ≤ 0.05). Confocal microscopy images showed morphological differences between micro-colonies with and without disruption treatment, suggesting that partial cell disruption by rapid depressurization improved the extraction of microalga compounds.

Título: Nutritional composition and acceptance of cake elaborated with beauregard potato biofortified with carotenoids / Composição nutricional e aceitação de bolo elaborado com batata beauregard biofortificada com carotenoides
Fonte: Biosci. j. (Online);35(3):949-956, may./jun. 2019. tab, graf.
Idioma: en.
Resumo: Beauregard biofortified sweet potato is a tuberous root with a high content of carotenoids whose consumption can bring beneficial effects on human health related to the biological actions of these substances. The objectives of this study were to evaluate the acceptance of cake made with sweet potato biofortified with carotenoids by school children enrolled in a school of the municipal education network of the city of Teresina PI. The sweet cake containing biofortified potato (Beauregard) (PC) was compared with standard sweet wheat flour (WC) cake formulation. The PC and WC products and the Beauregard potato were analyzed for centesimal composition (moisture, ashes, proteins, lipids and carbohydrates) and total carotenoid content. Acceptance of PC was assessed by means of an acceptance test with a hedonic scale of five points applied to 100 children from 08 to 10 years of age. The evaluation of the centesimal composition showed protein content corresponding to 2.1% in WC and 3.57% in PC, and of lipids of 5.16% in WC and 8.95% inPC. Regarding the moisture content, WC presented 32.5% and PC 38.44%. The content of fixed minerals (ash) found in formulations was 1.9% and 1.26%, respectively, in WC and PC. The carotenoid content (µg of ß-carotene.g-1) was significantly higher (p <0.05) in the biofortified potato (3,200.01 ± 0.02) and in the PC formulations (3,666.17 ± 2.55) and WC (3,066.53 ± 1.88) for common sweet potatoes (2.200,23 ± 1.63). In the five-point facial hedonistic acceptance test, the formulation containing biofortified potato (PC) obtained a significantly higher score (p <0.05) (4.24 ± 0.93) when compared to the WC formulation (3.75 ± 1.19). The biofortified potato and the cake containing the biofortified potato presented some characteristics related to the centesimal composition similar to those found in WC and the content of carotenoids in PC larger than those of WC. Because sweet cake is a food product, generally well accepted by children and adults, PC's greateracceptance of WC suggests its promising potential for consumption by the population.

A batata-doce Beauregard biofortificada é uma raiz tuberosa com alto teor de carotenoides, cujo consumo pode trazer efeitos benéficos na saúde humana relacionados com as ações biológicas dessassubstâncias. Os objetivos deste estudo foram avaliar a aceitação de bolo elaborado com batata doce biofortificada com carotenoides por crianças em idade escolar matriculados em uma escola da rede municipal de ensino da cidade de Teresina PI. O bolo doce contendo batata biofortificada (Beauregard) (BB) foi comparado com formulação padrão de bolo doce de farinha de trigo (BT). Os produtos BB e BT e a batata Beauregard foram analisados quanto à composição centesimal (umidade, cinzas, proteínas, lipídeos e carboidratos) e conteúdo de carotenóides totais. A aceitação do BB foi avaliada por meio de teste de aceitação com escala hedônica facial de cinco pontos aplicado em 100 crianças de 08 a 10 anos de idade. A avaliação da composição centesimal mostrou conteúdo protéico correspondendo 2,1% no BT e 3,57% no BB, e de lipídiosde 5,16% no BT e 8,95% no BB. Em relação ao teor de umidade, o BT apresentou 32,5% e BB 38,44%. O teor de minerais fixos (cinzas) encontrado nas formulações foi de 1,9% e 1,26%, respectivamente, no BT e BB. O conteúdo de carotenoides (µ g de ß-caroteno.g-1) foi significativamente maior (p<0,05) na batata biofortificada (3.200,01 ± 0,02) e nas formulações BB (3.666,17 ± 2,55) e BT (3.066,53 ± 1,88) em relação à Figure 1. Acceptance rate of Beauregard potato and wheat cake formulations.. batata doce comum (2.200,00 ± 1,63). No teste de aceitação escala hedonica facial de cinco pontos a formulação contendo batata biofortificada (BB) obteve nota significativamente maior (p<0,05) (4,24± 0,93) quando comparada com a formulação BT (3,75± 1,19). A batata biofortificada e o bolo contendo a batata biofortificada apresentaram algumas características relacionadas à composição centesimal semelhantes àquelas encontradas no BT e conteúdo de carotenoides no BB maiores que os do BT. Por ser o bolo doce um produto alimentício, de modo geral, bem aceito por crianças e adultos, a maior aceitação do BB em relação ao BT sugere seu potencial promissor para consumo pela população.

Resumo: O licopeno pode ser importante na prevenção e no tratamento do câncer porque possui vários mecanismos de ação anticarcinogênicos. Objetivo: Verificar quais fatores clínicos e/ou nutricionais e/ou laboratoriais estão associados às concentrações teciduais de licopeno no tecido oral neoplásico, em pacientes com cânceres da cavidade oral e da orofaringe. Casuística e Métodos: Estudo de caso, de corte transversal e prospectivo. Foram avaliados 37 pacientes homens e 11 mulheres, com idade entre 39 e 77 anos, sem tratamento anterior da doença. As seguintes informações foram obtidas : dados clínicos, nutricionais e laboratoriais. Para avaliar e ingestão habitual de carotenóides foi utilizado o questionário de freqüência alimentar quantitativo. As concentrações teciduais de carotenóides foram determinadas por cromatografia líquida de alta eficiência (HPLC). As associações foram examinadas pelas análises univariada (correlação de Spearman/Pearson) e de regressão linear múltipla, tendo a concentração de licopeno no tecido oral neoplásico como variável dependente. Resultados: A mediana e intervalos interquartis da concentração de licopeno no tecido oral neoplásico foram 1,15 (0,8-1,9)µmol/Kg. As concentrações de licopeno, no tecido oral neoplásico, foram associadas com as seguintes variáveis na análise univariada: idade (r=-0,38; P=0,027), concentrações séricas de licopeno (r=0,46: P=0,001), circunferência do braço (r=0,38: P=0,008) e circunferência muscular do braço (r=0,44: P=0,001). Na análise de regressão linear múltipla as variáveis determinantes das concentrações de licopeno no tecido oral neoplásico foram: palato mole (ß=0,699: P=0,017), creatinina sérica (ß=0,995: P=0,028), licopeno sérico (ß=1,628: P<0,001) e ß-caroteno sérico (ß=-2,106: P=0,003): estas quatro variáveis explicaram 41% da variação das concentrações teciduais de licopeno. Conclusões: Os fatores determinantes da concentração de licopeno no tecido oral neoplásico, foram: sítio do tumor...

Resumo: Background: Molluscs can accumulate carotenoids in their body tissues by predominantly feeding on aquatic plant sources. Carotenoid transport and absorption are determined by the regulation of various proteins such as Scavenger receptor class B(SR-BI). We report the identification and characterisation of pearl oyster Pinctada fuctada martensii SR-BI (PmSR-BI). The correlation between total carotenoid content (TCC) and gene expression was also estimated. Results: The full-length cDNA of PmSR-BI was 1828 bp, including an open-reading frame encoding of 1518 bp with a pI value of 5.83. PmSR-BI protein contains a hydrophobic CD36 domain and four centrally clustered cysteine residues for the arrangement of disulphide bridges. The deduced amino acid sequence had an identity of 30% to 60% with the SR-B of other organisms. Reverse transcription polymerase chain reaction analysis showed that mRNA transcripts were expressed in multiple tissues of adult pearl oyster. A higher expression of PmSR-BI gene was observed in the hepatopancreas than in the adductor muscle, gill and mantle. The TCC and gene expression of PmSR-BI were significantly correlated (P b 0.05), with a correlation coefficient of 0.978. Conclusions: The results suggested that PmSR-BI is involved in the absorption of carotenoids in the pearl oyster P. fuctada martensii.

Resumo: ABSTRACT Nowadays consumers are more concerned about food quality as well as how food is produced. Moreover, consumer demand for more natural, nutritious, safer to eat, and environmentally sustainable food has drawn attention to alternative breeding systems, such as a free-range system. Hens' eggs represent a rich source of important nutrients, including lipids and carotenoids. A detailed characterization of the nutritional and lipid profile of free-range chicken eggs from family farms was carried out. The chemical composition of the free-range egg yolks confirmed the advantages of this farming system, as a relevant source of unsaturated fatty acids and carotenoids, functional compounds in the human diet. These findings can help improve income generation, food supplementation, and consolidation of the family farming system.

Resumo: The chemical composition of the essential oil and carotenoid content of the parasitic plant Cuscuta mitraeformis are described for the first time. The essential oil was analyzed by GC-FID and GC-MS revealing nonanal (24.6%) as the main constituent followed by thymol (16.5%) and eugenol (7.5%). The total carotenoid content (130 mg 100 g-1 FW) was determined by HPLC-DAD. The carotenoid fraction contained ß-carotene (76.4 mg 100 g-1 FW) and lutein (18.9 mg 100 g-1 FW) as the most abundant compounds. A weak antioxidant activity was observed by the essential oil against DPPH radical (IC50, 1.4 mg mL-1), whereas a strong antioxidant activity was determined for the carotenoid fraction (IC50, 60.1 µg mL-1). The essential oil inhibited the growth of Clavibacter michiganensis, Pseudomonas syringae pv. tomato and Erwinia carotovora with minimum inhibitory concentrations of 122.5, 184.5, 234.2 µg mL-1, respectively.

Título: Effect of initial pH of medium with potato wastewater and glycerol on protein, lipid and carotenoid biosynthesis by Rhodotorula glutinis
Fonte: Electron. j. biotechnol;27:25-31, May. 2017. tab, graf.
Idioma: en.
Resumo: Background: Rhodotorula glutinis is capable of synthesizing numerous valuable metabolites with extensive potential industrial usage. This paper reports the effect of initial culture medium pH on growth and protein, lipid, and carotenoid biosynthesis by R. glutinis. Results: The highest biomass yield was obtained in media with pH 4.0­7.0, and the value after 72 h was 17.2­19.4 gd.w./L. An initial pH of the medium in the range of 4.0­7.0 has no significant effect on the protein (38.5­41.3 g/100 gd.w.), lipid (10.2­12.7 g/100 gd.w.), or carotenoid (191.7­202.9 µg/gd.w.) content in the biomass or on the profile of synthesized fatty acids and carotenoids. The whole pool of fatty acids was dominated by oleic (48.1­53.4%), linoleic (21.4­25.1%), and palmitic acids (13.0­15.8%). In these conditions, the yeast mainly synthesized torulene (43.5­47.7%) and ß-carotene (34.7­38.6%), whereas the contribution of torularhodin was only 12.1­16.8%. Cultivation in medium with initial pH 3.0 resulted in a reduction in growth (13.0 gd.w./L) and total carotenoid (115.8 µg/gd.w.), linoleic acid (11.5%), and torularhodin (4.5%) biosynthesis. Conclusion: The different values of initial pH of the culture medium with glycerol and deproteinized potato wastewater had a significant effect on the growth and protein, lipid, and carotenoid biosynthesis by R. glutinis.
