Title: DEGRADATION OF AZO AND TRIPHENYLMETHANE DYE BY THE BACTERIA ISOLATED FROM LOCAL INDUSTRIAL WASTE

The isolate SCWS5 was selected based on its maximum decolorization of dyes Methyl orange, Congo red and Malachite green (each 150mg/L). Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence confirmed SCWS5 as Bacillus sp. On physiochemical parameters optimization, Bacillus sp. SCWS5 degraded 10.13% (0.15mg/mL), 11.76% (0.11mg/mL) and 9.32% (0.8mg/mL) of Methyl orange, Congo red and Malachite green, respectively within 2h whilst 100% degradation (2.97mg/mL) at 18h for Methyl orange, 100% (2.43mg/mL) at 16h for Congo red and 100% (3.18mg/mL) at 20h for Malachite green were recorded. The degraded products were found non-toxic in nature while bacterial cells showed elongation and membrane rupturing under SEM taken from dye degraded media.Read More
