“…The role of bacterial cells in the remediation of textile effluents has been trustworthy in the recent past . The mixed bacterial population from our previous finding was capable of detoxifying and mineralizing AR88 and this mixed bacterial culture was used for isolating a bacterial strain capable of decolorizing MV.…”

An indigenous bacterium, Bacillus mannanilyticus strain AVS from an acclimated mixed bacterial culture was screened to biotransform a triphenylmethane dye; methyl violet (MV). The strain was acclimated to MV structure and thus, the cells exhibited an average decolorization rate (ADR) of 69.44 μg min−1 with simultaneous reduction in chemical oxygen demand (COD) level (94%) when incubated for 24 h under static condition. The inducible extracellular oxidoreductases catalyzed MV biotransformation and produced metabolites which were devoid of chlorine. The phytotoxicity assays assessed the toxicity of the biotransformed products. This is the first report on TPM dye degradation and mineralization using B. mannanilyticus strain AVS. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 394–403, 2017

BACKGROUND Immobilization of more than one peroxidase on the same support is an ideal technology for application because such a multi‐enzyme catalytic system may show high activity over a very wide optimal range of pH, temperature and H2O2 concentration. In this work, chloroperoxidase (CPO) and horseradish peroxidase (HRP) were co‐immobilized on ZnO nanowires/macroporous SiO2 composite support through an in situ cross‐linking method. An anionic bi‐epoxy cross‐linker was used by adsorption on the surface of ZnO nanowires before cross‐linking. RESULTS The cross‐linking was carried out under suitable conditions: pH 6.5, reaction temperature 15°C and reaction time 15 h. Using a 1/1 mixture of CPO and HRP resulted in a co‐immobilized enzyme with loading 79.6 mgCPO g‐1support and 52.8 mgHRP g‐1support, and total specific activity up to 15.7 U per mgsupport. The co‐immobilized enzyme also showed good stability after 60 days of storage, and excellent reusability over 20 repeat uses. CONCLUSIONS For the decolorization of azo dyes the co‐immobilized CPO (60%)/HRP (40%) exhibited high catalytic activity over very wide ranges of pH, temperature and H2O2 concentration. Using this robust biocatalyst, complete decolorizations of azo dyes have been realized within 3 h of reaction. © 2017 Society of Chemical Industry

“…Though pigments or colorific make the world glower, at the same time it is a serious problem both biological and aesthetical as well, because of water coloration and changes or stopping photosynthesis process in the water ecosystem. Pigments in water or stain is the most obvious and common pollutants gauge and, effusion with high synthetic concentration of dye may cause a great damage to water bodies because of toxic compounds, mutagenic or carcinogenic (1,2,3), so it is necessary to treat all debris before effusion.…”

Objective. Decoloring wastewater from a paint factory making use of Chlorella sp., microalgae as a biological way of treatment. Materials and methods. Samples of this microalgae previously cultivated with nourishing fertilizer under photoperiods of light and darkness were taken to test the microalgae Chlorella sp., initial concentration effect in the bioremoval process. For this purpose, it was cultivated in 0.10, 0.20 and 0.30 units of absorbance in bioreactors with 200 mL wastewater with and without nutrients. The biotest with the best rate of colour removal was chosen and the DBO5 and DQO were marked out. The immobilized Chlorella sp., in kappa carrageenan was also tested. Results. In the tests colour decrease percentage were 81.7, 69.7 and 58.3% without nutrients in the initial concentrations of 0.10, 0.20 and 0.30 units of absorbance respectively and 72.6, 69.0 and 86.8% for 0.10, 0.20 and 0.30 units of absorbance with nutrients respectively in the day of maximum growth. The immobilized microalgae score were 72.60% and 78.36% of color removal for 0.4 and 1.6 units of absorbance respectively. The higher colour removal test score was that with nutrients at 0.30 units of absorbance with several changes in DBO5 and DQO values. Conclusion. The biological wastewater treatment making use of Chlorella sp., microalgae can be considered as an effective choice in decolorating wastewater.
