Biodegradation of ochratoxin A for food and feed decontamination
Description :
Ochratoxin A (OTA) is one of the most important mycotoxins that is found in food and feed products. It has proven toxic properties, being primarily known for its nephrotoxicity and carcinogenicity to certain animal species. OTA is produced by several species of Aspergillus and Penicillium that can b...

Studies of decolorization of azo dyes by ascomycete yeasts
Description :
Azo dyes are the most widely used colored materials in textile industries and its biodegradability is, therefore, an important issue in the biological treatment of dye-containing wastewater. However, these treatments are not totally effective in removing color of textile dye wastewater since dyes ar...

Fluorene and phenanthrene uptake by Pseudomonas putida ATCC 17514 : kinetics and physiological aspects
Description :
Pseudomonas putida ATCC 17514 was used as
a model strain to investigate the characteristics of bacterial
growth in the presence of solid fluorene and phenanthrene.
Despite the lower water-solubility of phenanthrene, P.
putida degraded this polycyclic aromatic hydrocarbon
(PAH) at a maximum observed ...

Fate of aniline and sulfanilic acid in UASB bioreactors under denitrifying conditions
Description :
Two upflow anaerobic sludge blanket (UASB) reactors were operated to investigate the fate of aromatic amines under denitrifying conditions. The feed consisted of synthetic wastewater containing aniline and/or sulfanilic acid and a mixture of volatile fatty acids (VFA) as the primary electron donors....

Removal of organic compounds by a biofilm supported on GAC : modelling of batch and column data
Description :
The performance of a biofilm of Arthrobacter viscosus supported on granular activated carbon on the retention of organic compounds was evaluated. The presence of functional groups on the cell wall surface of the biomass that may interact with the organic compounds was confirmed by Fourier transform ...

Biotransformation of phenolics with laccase containing bacterial spores
Description :
Treatment of effluents containing phenols such as textile dyes with fungal laccases is usually limited to the acid to neutral pH range and moderate temperatures. Here we demonstrate for the first time that spore-bound laccases which are stable at high temperatures and pH values can be used for pheno...

Anaerobic decolorization of an azo dye by a mixed culture
Description :
Wool dyeing wastewater contains xenobiotic compounds that can be removed by biotechnological processes. Studies on various dyes showed that anaerobic processes are suitable to alter azo dyes as a first step of the biodegradation process. These compounds are reduced by anaerobic consortia to aromatic...

Reductive biological treatment of textile effluents
Description :
Azo dyes are synthetic organic colorants which are extensively used in textile, food and cosmetic industries. A large fraction of these dyes is released into the environment even after conventional wastewater treatments. This is a worldwide problem and particularly a problem in regions where textile...
