“…All enzyme activities were assayed in cell-free extract as well as in culture media at room temperature (25 uC). Laccase and tyrosinase activities were determined according to previously reported methods (Tamboli et al, 2010b;Waghmode et al, 2011b). One unit of tyrosinase activity was equal to a DA 265 of 0.001 min 21 at pH 6.5 and 25 uC in a 3.0 ml reaction mixture containing L-catechol and L-ascorbic acid.…”

Galactomyces geotrichum MTCC 1360 showed 87 % decolorization of the azo dye Rubine GFL (50 mg l "1 ) within 96 h at 30 6C and pH 7.0 under static conditions, with significant reduction of chemical oxygen demand (67 %) and total organic carbon (59 %). Examination of oxidoreductive enzymes, namely laccase, tyrosinase and azo reductase, confirmed their role in decolorization and degradation of Rubine GFL. Biodegradation of Rubine GFL into different metabolites was confirmed using high-performance TLC, HPLC, Fourier transform IR spectroscopy and GC-MS analysis. During toxicological studies, cell death was observed in Rubine GFL-treated Allium cepa root cells. Toxicological studies before and after microbial treatment were done with respect to cytotoxicity, genotoxicity, oxidative stress, antioxidant enzyme status, protein oxidation and lipid peroxidation using root cells of A. cepa. The analysis with A. cepa showed that the dye exerts oxidative stress and subsequently has a toxic effect on the root cells, whereas its metabolites are less toxic. Phytotoxicity studies revealed the less toxic nature of the metabolites as compared with Rubine GFL.

“…is a Gram-negative, rod-shaped, aerobic species. Some strains of Sphingobacterium are able to degrade mefenacet when used as the sources of carbon and energy, and decolorize the dye Direct Blue GLL (Ye et al 2004;Tamboli et al 2010). The ability of these three isolated bacterial strains to degrade methomyl, with or without the presence of glucose, is shown in Fig.…”

Complex microbial communities from river biofilms might contain microorganisms capable of degrading xenobiotic pollutants such as pesticides (e.g. methomyl, which is commonly detected in rivers). Therefore, this study was used to determine the methomyl degradation potential of bacteria consortia and single bacterial strains acclimatized and isolated from natural river biofilms to provide biomaterials for bioremediation of water that is contaminated with methomyl. Natural river biofilms were culture enriched with methomyl as the sole carbon source to obtain acclimatized bacterial consortia and single bacterial strains. The microbial consortium on the ceramic discs was able to remove 91 % of added methomyl (50 mg l -1 ) in 7 days. The longer-acclimatized bacterial consortium on loofah sponges removed methomyl more quickly than the shorter-acclimatized consortium, but both had similar removal capabilities (i.e. 92.4 and 92.2 %). This finding suggested that the former might contain more methomyl degraders than the latter. However, after preservation at 25, 4 and -20°C for 1 or 3 months, the methomyl degradation ability of the bacterial consortia decreased significantly, indicating loss of methomyl degraders during preservation. Three bacterial species were isolated from acclimatized river biofilms, and only one species, identified as Sphingomonas sp., was able to remove methomyl, with a 7-day removal rate of 44.7 % when sugar was added and of 32.5 % when no sugar was added. These results suggested that an additional carbon source might slightly improve the ability of Sphingomonas sp. to degrade methomyl. Acclimatized bacterial consortia have a higher potential for treating methomyl-contaminated water than isolated bacterial species.

“…Bioremediation is the use of living organisms for the recovery or cleaning up of contaminated sites (soil, sediment, air, water). Many microorganisms are capable of degrading textile dyes, including bacteria [7], fungi [8], yeast [9], actinomycetes [10] and algae [11]. Scientists have now realized that plants also have complex systems and can be used as a remediating tool.…”
