Rapid decolorization of synthetic melanoidin by bacterial extract and their mediated silver nanoparticles as supportR. Palani velana, P.M. Ayyasamya, R. Kathiravanb, B. Subashnic

Background: Shewanella species belonging to dissimilatory metal bacteria were found to decolorize most textile dyes and had also attracted great interests in regard to bioremediation. However, studies have rarely been reported on Shewanella xiamenensis BC01, which was isolated as a biodecolorization and bioelectricity strain recently. In this study, the effect of cultivation conditions on S. xi...

Methylene Blue (MB) is one kind of textile dye from thiazine dyes that negatively impacts humans and the environment. Therefore, it very important to determine an effective method decolorize it. Brown-rot fungus Gloeophyllum trabeum can MB, but its ability was still relatively low required a long incubation time. In this study, effect adding bacterium Pseudomonas aeruginosa at 2, 4, 6, 8, 10 mL...

This study reported methylene blue (MB) dye decolorization by using mixed consortium culture, brown-rot fungus (BRF) Gloeophyllum trabeum which is known as degradative with bacterium Bacillus subtilis addition. B. were added into G. cultures at variation 2, 4, 6, 8, and 10 mL incubated statically (1 = 9.47 × 108 CFU). All of had ability to decolorize MB (100 mg/L) in potato dextrose broth (PDB)...

Biosorption of dyes by lignocelluloses may be an effective method for removing dyes from textile effluents. However, the resulting dyeadsorbed lignocellulosic materials may constitute another pollution problem. An integrated method can solve this problem. Here, various lignocelluloses were tested for their Astrazon Black and Astrazon Blue dyes removal activities. The dye adsorbed after 30 min c...

Kokuto-shochu is a traditional Japanese distilled liquor made from brown sugar. Kokuto-shochu distillery wastewater (KDW) contains high concentrations of organic compounds and brown pigments (called molasses pigments) which are hardly decolorized by general biological wastewater treatment. A fungus, Penicillium oxalicum d, which we isolated in a previous study, decolorizes 47% of the color from...
