Lignin is a major component of soil organic matter and also a rich source of carbon dioxide in soils. However, because of its complex structure and recalcitrant nature, lignin degradation is a major challenge. Efforts have been made from time to time to understand the lignin polymeric structure better and develop simpler, economical, and bio-friendly methods of degradation. Certain enzymes from...
The decolouration of the metal-complex dyes Bemaplex Navy M-T (150 mg/L) and Bezaktiv Blue BA (150 mg/L) in nine successive batches by immobilised cultures of the white-rot fungus Trametes pubescens was studied. Two different types of immobilisation supports were used: the commercial carriers Kaldnes™ K1 (synthetic supports) and sunflower-seed shells (SS) (natural supports). Bemaplex showed mor...
Studies were carried out on the decolorization of azo dyes by Bacillus species from effluent of textile industries. About 10 bacterial strains were isolated from the effluent of textile industries, Bacillus sp. showed remarkable ability in decolorizing the widely utilized azo dyes. Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence comparisons indicate that these s...
In the present study, biotransformation of Remazol Orange 3R (RO3R) was studied using well-known bacterial isolate Pseudomonas aeruginosa strain BCH. The dye was decolorized up to 98 % within 15 min. The induction in the level of various oxidoreductive enzymes viz. laccase, tyrosinase, veratryl alcohol oxidase and DCIP reductase were observed in the cells obtained after decolorization of RO3R, ...
Two mesophilic streptomycetes (S. violaceoruber and S. spiroverticillatus) were selected to study their Poly R-478 decolorization ability and lignocellulose solubilizing activity. Both strains were able to degrade Poly R-478 dye and ferulic acid during growth on a minimal salts medium. The Poly R-478 decolorizing activities of both strains were induced by adding different carbon sources to the ...
Biodegradation of Model Azo Dye Methyl Red and other Textile Dyes by Isolate Bacillus circulans NPP1
Well-established biodegradation tests use biogenously evolved carbon dioxide (CO(2)) as an analytical parameter to determine the ultimate biodegradability of substances. A newly developed analytical technique based on the continuous online measurement of conductivity showed its suitability over other techniques. It could be demonstrated that the method met all criteria of established biodegrada...
