Título: Diversidad bacteriana en el biocátodo reductor de Cr(VI) de una Celda de Combustible Microbiana con puente salino / Bacterial diversity in the Cr(VI) reducing biocathode of a Microbial Fuel Cell with salt bridge
Fonte: Rev. argent. microbiol;51(2):110-118, jun. 2019. ilus, tab.
Idioma: en.
Resumo: Although Cr(VI)-reducing and/or tolerant microorganisms have been investigated, there is no detailed information on the composition of the microbial community of the biocathode microbial fuel cell for Cr(VI) reduction. In this investigation, the bacterial diversity of a biocathode was analyzed using 454 pyrosequencing of the 16S rRNA gene. It was found that most bacteria belonged to phylum Proteobacteria (78.8%), Firmicutes (7.9%), Actinobacteria (6.6%) and Bacteroidetes (5.5%), commonly present in environments contaminated with Cr(VI). The dominance of the genus Pseudomonas (34.87%), followed by the genera Stenotrophomonas (5.8%), Shinella (4%), Papillibacter (3.96%), Brevundimonas (3.91%), Pseu-dochrobactrum (3.54%), Ochrobactrum (3.49%), Hydrogenophaga (2.88%), Rhodococcus (2.88%), Fluviicola (2.35%), and Alcaligenes (2.3%), was found. It is emphasized that some genera have not previously been associated with Cr(VI) reduction. This biocathode from waters contaminated with tannery effluents was able to remove Cr(VI) (97.83%) in the cathodic chamber. Additionally, through use of anaerobic sludge in the anodic chamber, the removal of 76.6% of organic matter (glucose) from synthetic waste water was achieved. In this study, an efficient biocathode for the reduction of Cr(VI) with future use in bioremediation, was characterized.

Aunque se ha investigado sobre los microorganismos reductores y/o tolerantes de Cr(VI), no hay información detallada sobre la composición de la comunidad microbiana del cátodo de una Celda de Combustible Microbiana para la reducción de Cr(VI). En esta investigación se analizó la diversidad bacteriana de un biocátodo usando pirosecuenciación 454 del gen 16S rRNA. Se encontró que la mayoría de las bacterias pertenecieron a los filos Proteobac-teria (78,8%), Firmicutes (7,9%), Actinobacteria (6,6%) y Bacteroidetes (5,5%), comúnmente presentes en ambientes contaminados con Cr(VI). Se encontró como género dominante a Pseudomonas (34,87%), seguido por los géneros Stenotrophomonas (5,8%), Shinella (4%), Papil-libacter (3,96%), Brevundimonas (3,91%), Pseudochrobactrum (3,54%), Ochrobactrum (3,49%), Hydrogenophaga (2,88%), Rhodococcus (2,88%), Fluviicola (2,35%) y Alcaligenes (2,3%). Se destaca que algunos géneros no han sido previamente asociados con la reducción de Cr(VI). Este biocátodo procedente de aguas contaminadas con efluentes de curtiembres fue capaz de remover Cr(VI) (97,83%) en la cámara catódica. Adicionalmente, a través del uso de lodo anaeróbico en la cámara anódica, se logró la remoción del 76,6% de materia orgánica (glucosa) a partir de agua residual sintética. En este estudio se caracterizó un eficiente biocátodo para la reducción de Cr(VI) con futuro uso en biorremediación.

Objectives: the objective of this study was to support microbiological quality assurance in a vaccine production plant through identification of environmental microbiological charge and its behavior with routine disinfectants. Methods: the existing flora of each classified area was studied. Air samples taken by volumetric and plate sedimentation methods were analyzed. Surfaces and the gown of the staff were assessed by contact method. Genera and species were identified, thus setting a Group of Indicator Microorganisms made up of microorganisms that were isolated at a rate greater than 5 percent for each facility. Results: animal Facility: Staphylococcus spp (50 percent), Aerococcus spp (21 percent), Micrococcus spp (10 percent), Bacillus spp and related genera (6 percent); Normal Tissue Culture Laboratory: Staphylococcus spp (48 percent), Micrococcus spp (34 percent), Bacillus spp and related genera (13 percent); Quality Control Laboratory: Staphylococcus spp (50 %), Micrococcus spp (27 percent), Kocuria spp (9 percent), Bacillus spp and related genera (7 percent); Production: Staphylococcus spp (50 percent), Micrococcus spp (17 percent), Kocuria spp (11 percent), Leuconostoc spp (8 percent), Bacillus spp and related genera (6 percent). The Group of Indicator Microorganisms for the Production Unit was identified as Staphylococcus spp (49.5 percent), Micrococcus spp (23 percent) and Bacillus spp and related genera (8.1 percent). The regularly used disinfectants for strains from the Group of Indicator Microorganisms showed a high microbicidal efficacy. Conclusion: the results provide information about the environmental bioburden, which will be useful for the understanding of the microbial entry points and spreading and the implementation of measures to prevent microbial contamination, so critical for manufacture of safe, pure and effective vaccines(AU)

Título: Aislamiento de Aspergillus tritici desde ambiente interno (Chile): alcances ecológicos y clínicos / Isolation of Aspergillus tritici from internal environment (Chile): Ecological and clinical scope
Fonte: Rev. argent. microbiol;51(1):66-70, mar. 2019. ilus.
Idioma: es.
Resumo: Los ambientes internos son un hábitat protector importante, donde el hombre reside o trabaja la mayor parte de su tiempo. Muchos de estos ambientes carecen de buena ventilación, lo que influye en la composición de sus comunidades microbianas y, en especial, de la fúngica. El objetivo de este estudio es comunicar la presencia de Aspergillus de la sección Candidi en ambientes internos de la Escuela de Medicina de la Universidad de Valparaíso, Chile, y destacar su rol ecológico y su importancia en micología médica. Se efectuó la clasificación morfofisiológica y molecular de dichos aislamientos. Se realizó un muestreo no volumétrico ambiental en agar papa glucosado (PDA) mediante la exposición de 2 placas en 10 diferentes ambientes internos para seleccionar las especies de Aspergillus. Se efectuaron subcultivos en agar Czapek con extracto de levadura (CYA), agar extracto de malta (MEA) y agar creatina sacarosa (CREA) solo para las especies de esporas blancas, para su identificación morfofisiológica y posteriormente molecular. De 20 muestras analizadas, en solo una se aisló un miembro de Aspergillus perteneciente a la sección Candidi. Sobre la base de sus características morfológicas y moleculares, se clasificó a este aislamiento como Aspergillus tritici Mehrotra & Basu. Se describe su ecología y se discute su importancia médica.

Indoor environments provide important protective habitats for humans, who live or work in them most of the time. Many of these environments lack ventilation, which affects the composition of microbial communities, especially that of the fungal community. The aim of this study is to report the isolation of Aspergillus section Candidi from indoor environments of the School of Medicine at Universidad de Valparaiso, Chile, and identification through morpho-physiological and molecular approaches. Their ecological and clinical features were highlighted. An environmental non-volumetric sampling was performed on PDA medium; 2 petri dishes were exposed in 10 different places to select the Aspergillus samples. Subcultures were performed on agar Czapek with yeast extract (CYA), malt extract agar (MEA) and creatin sacarose agar (CREA) media only for the morpho-physiological and later the molecular identification of white spore species. Of the 20 samples analyzed, one Aspergillus belonging to Candidi section was isolated. Based on its morphology and molecular features, it was classified as Aspergillus tritici Mehrotra & Basu. Its ecology and medical relevance are reviewed and discussed.

Título: Establecimiento de límites microbiológicos internos para áreas clasificadas Grado D / Establishing internal microbiological limits for D grade-classified areas
Fonte: Rev. cuba. farm;50(1), ene.-mar. 2016. tab.
Idioma: es.
Resumo: Objetivo: contribuir al aseguramiento de la calidad microbiológica de una planta de producción de vacunas, a través del establecimiento de límites internos de alerta y de acción para sus áreas clasificadas Grado D. Métodos: se estudió la microbiota residente de cada área clasificada Grado D. Se analizaron muestras de aire tomadas por el método volumétrico. Las superficies e indumentaria del personal fueron evaluadas por el método de contacto. Los recuentos de microorganismos fueron analizados estadísticamente para la determinación de los límites de alerta y de acción. Resultados: se establecieron los límites de alerta y de acción microbiológicos para cada área clasificada Grado D de la planta de producción del Instituto Nacional de Enfermedades Virales Humanas basados en la determinación de los rangos habituales de trabajo. Se establecieron límites, como en el caso de guantes pos trabajo para un área Grado D, donde la norma no los define. Conclusiones: se mostró concordancia con los límites recomendados por la autoridad regulatoria nacional ANMAT y proporcionó información sobre la carga microbiológica de los ambientes clasificados Grado D, que será de utilidad tanto para la comprensión del ingreso y circulación de microorganismos como para la implementación de medidas para prevenir la contaminación microbiana, aspectos críticos en la fabricación de vacunas seguras, puras y eficaces(AU)

Objective: to contribute to ensuring the microbiological quality of a vaccine manufacturing plant through the establishment of internal microbiological alert and action limits for their grade D classified areas. Methods: the resident microbiota of each grade D classified area was studied. Air samples taken by the volumetric method were analyzed. The surfaces and the staff's gowning were evaluated by the contact method. The microorganism counts were statistically analyzed to determine the alert and action limits. Results: the microbiological alert and action limits have been established for each Grade D classified area of the production plant of the National Institute of Human Viral Diseases, based on the determination of the usual working ranges. Limits were set, as in the case of gloves after work for a Grade D area, where the standard does not define them. Conclusions: the results generally agreed with the limits recommended by the national regulatory authority ANMAT, and additionally, this study provided information on the microbiological flora of grade D classified environments, which will be useful for both understanding the entrance and circulation of microorganisms and implementing measures to prevent biocontamination, which are critical aspects in the manufacture of effective, pure and safe vaccines(AU)

Resumo: ABSTRACT We studied the effects of particulate and dissolved optically active components on the attenuation of photosynthetic active radiation (PAR) in a tropical lake. The temporal and spatial distribution of tripton, Chl-a and aCDOM(440) and their relative contribution to the diffuse PAR attenuation coefficient (Kd) was investigated at 21 sites (dry and wet seasons and two intermediate periods) and at monthly interval at 1 pelagic site. Higher values of ​​ Kd were observed during the mixing period, characterized by a higher concentration of tripton and Chl-a compared to the stratified rainy season. In the spatial sampling PAR attenuation was dominated by tripton absorption/scattering (average relative contribution of 79%), followed by Chl-a (average 11.6%). In the monthly sampling tripton and Chl-a accounted for most of the Kd with relative contributions of 47.8% and 35.6%, respectively. Multiple linear regression analysis showed that Chl-a and tripton in combination explained 97% of the monthly variation in Kd (p<0.001), but Chl-a had more influence (higher regression coefficient). Thus, although most of light attenuation was due to tripton, seasonal variations in phytoplankton abundance were responsible for most of the temporal fluctuations in Kd.

Título: Richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides in rice paddy fields
Fonte: An. acad. bras. ciênc;89(1):355-369, Jan,-Mar. 2017. tab.
Idioma: en.
Resumo: ABSTRACT The objective of this study was to verify the richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides of the rice paddy fields. In the crop seasons of 2012/13 and 2013/14, field experiments were performed, which consisted of single-dose applications of the fungicides trifloxystrobin + tebuconazole and tricyclazole, and the insecticides lambda-cyhalothrin + thiamethoxam and diflubenzuron, in 10 m2 experimental plots, over rice plants in the R3 stage. Control plots with and without rice plants were maintained in order to simulate a natural environment. Soil samples were collected during rice cultivation for assessment of the macroinvertebrate fauna. Chemical-physical parameters assessed in the experiments included temperature, pH and oxygen dissolved in the water and pesticide persistence in the water and in the soil. The application of a single dose of the pesticides and fungicides in the recommended period does not cause significant negative effects over the richness and density of the macroinvertebrates. Tebuconazole, tricyclazole and thiamethoxam showed high persistence in the irrigation water of rice paddy fields. Thus, the doses and number of applications of these products in crops should be carefully handled in order to avoid contamination of the environment.

Resumo: ABSTRACT Coral reefs are one of the most vulnerable ecosystems to ocean warming and acidification, and it is important to determine the role of reef building species in this environment in order to obtain insight into their susceptibility to expected impacts of global changes. Aspects of the life history of a coral population, such as reproduction, growth and size-frequency can contribute to the production of models that are used to estimate impacts and potential recovery of the population, acting as a powerful tool for the conservation and management of those ecosystems. Here, we present the first evidence of Siderastrea stellata planulation, its early growth, population size-frequency distribution and growth rate of adult colonies in Rocas Atoll. Our results, together with the environmental protection policies and the absence of anthropogenic pressures, suggest that S. stellata population may have a good potential in the maintenance and recovery in the atoll. However, our results also indicate an impact on corals' recruitment, probably as a consequence of the positive temperature anomaly that occurred in 2010. Thus, despite the pristine status of Rocas Atoll, the preservation of its coral community seems to be threatened by current global changes, such as more frequent thermal stress events.
