CO2 Production of Soil Microbiota in the Presence of Ametryne and Biofertilizer
(Water Air And Soil Pollution, 2014-12-01) [Artigo]
Ametryne is an herbicide applied to sugar cane cultures to prevent the emergence of weeds. It is a persistent compound that percolates ground and surface water thus impacting aquatic communities. In this study, we evaluated ...
Comparative Analysis of Azo Dye Biodegradation by Aspergillus oryzae and Phanerochaete chrysosporium
(Water Air And Soil Pollution, 2014-07-01) [Artigo]
The textile industry often releases effluents into the environment without proper treatment or complete dye removal. Azo dyes, which are characterized by azo groups (-N=N-), are frequently used in the textile industry. ...
Asymmetric chromosome segregation in Xanthomonas citri ssp. citri
(Microbiologyopen, 2014-02-01) [Artigo]
This study was intended to characterize the chromosome segregation process of Xanthomonas citri ssp. citri (Xac) by investigating the functionality of the ParB factor encoded on its chromosome, and its requirement for cell ...
Effect of C/N Ratio and Physicochemical Conditions on the production of Rhamnolipids by Pseudomonas Aeruginosa LBI
(Research Journal of Biotechnology, 2010-08-01) [Artigo]
Waste utilization for biosurfactant production is an important approach contributing to the reduction of waste treatment costs, while increasing the economic value of residues and reducing biosurfactant production costs: ...
Planting of fungus onto hibernating workers of the fungus-growing ant Mycetosoritis clorindae (Attini, Formicidae)
(Insectes Sociaux, 2010-05-01) [Artigo]
We describe a peculiar fungus-coating behavior of the attine ant Mycetosoritis clorindae, where workers plant fungal mycelium on hibernating nestmates. Hibernating nestmates become ultimately enveloped in a live mycelial ...
Assessing Bacillus subtilis biosurfactant effects on the biodegradation of petroleum products
(Environmental Monitoring And Assessment, 2015-01-01) [Artigo]
Microbial pollutant removal capabilities can be determined and exploited to accomplish bioremediation of hydrocarbon-polluted environments. Thus, increasing knowledge on environmental behavior of different petroleum products ...
Production of xylanolytic enzymes by Penicillium janczewskii
(Bioresource Technology, 2010-06-01) [Artigo]
The production of extracellular xylanase, beta-xylosidase and alpha-L-arabinofuranosidase by the mesophilic fungus Penicillium janczewskii under submerged cultivation was investigated with different carbon sources. ...
Analytical Methods in Photoelectrochemical Treatment of Phenol
(Journal of the Brazilian Chemical Society, 2011-09-01) [Artigo]
The aim of the study was to propose a treatment of simulated wastewater containing phenol by photocatalytic and photolytic processes and analyze the toxicity of these phenolic solutions. Two treatment systems were performed ...
Biodegradation and toxicological evaluation of lubricant oils
(Brazilian Archives of Biology and Technology, 2012-12-01) [Artigo]
The aim of this work was to compare different toxicity levels of lubricant oils. The tests were performed using the earthworm (Eisenia andrei), arugula seeds (Eruca sativa) and lettuce seeds (Lactuca sativa), with three ...
Morphological, mechanical properties and biodegradability of biocomposite thermoplastic starch and polycaprolactone reinforced with sisal fibers
(Journal of Reinforced Plastics and Composites, 2012-04-01) [Artigo]
The incorporation of fibers as reinforcements in polymer composites has increased due to their renewability, low cost and biodegradability. In this study, sisal fibers were added to a polymer matrix of thermoplastic starch ...
