“…Brevibacillus laterosporus MTCC 2298 is an aerobic bacterium which contains various biotransformation enzymes viz. aminopyrine N‐demethylase, NADH‐DCIP reductase, Malachite green (MG) reductase, lignin peroxidase, laccase and tyrosinase (Gomare 2007). Hence, this strain has been exploited for the decolourization of different azo dyes.…”

Aims: To evaluate the potential of Brevibacillus laterosporus MTCC 2298 for the decolourization of different textile azo dyes including methyl red, mechanism of biotransformation and the toxicity of products. Methods and Results: Brevibacillus laterosporus showed decolourization of thirteen different azo dyes including methyl red. Decolourization of methyl red was faster (93% within 12 h) under static condition at the concentration 0·2 g l−1. Induction in the activities of lignin peroxidase, laccase, aminopyrine N‐demethylase, NADH‐DCIP reductase and malachite green reductase was observed in the cells obtained after decolourization. Fourier transform infra‐red spectral analysis of products indicated conversion of methyl red into secondary aryl amines and nitrosamines, which further transformed into the aromatic nitro compounds. Gas chromatography–mass spectroscopy analysis suggested conversion of methyl red into high molecular weight complex derivatives. The heterocyclic substituted aryl amine (m/z 281), p‐(N,N di formyl)‐substituted para‐di amino benzene derivative (m/z 355) and p‐di‐amino benzene derivative (m/z 282) are the mainly elected biotransformation products. Microbial and phytotoxicity studies suggested nontoxic nature of the biotransformation products. Conclusions: Brevibacillus laterosporus has potential for the decolourization of different textile azo dyes. Significance and Impact of the Study: Brevibacillus laterosporus decolourized different azo dyes including methyl red and can be utilized for textile dye decolourization.

This comparative study disclosed the diverse catalytic activities of Brevibacillus laterosporus on two different azo dyes. It decolorized 100% of Remazol red and 95% of Rubine GFL within 30 and 48 h respectively, under static condition at 50 mg l⁻¹ dye concentration. Significant increase was observed in azo reductase, NADH-DCIP reductase, veratryl alcohol oxidase and tyrosinase in cells obtained after decolorization of Remazol red; whereas these values were much different with complete inhibition of azo reductase during decolorization of Rubine GFL. The plausible pathway of dye degradation obtained from Gas chromatography-Mass spectroscopy (GC-MS) data confirmed the different metabolic fate of these structurally unidentical dyes. FTIR and HPTLC analysis of extracted metabolites confirmed the biodegradation, while phytotoxicity study assured the detoxification of both the dyes studied. The results obtained in this study suggests, i) sulpho and hydroxyl group present at ortho position to azo group stimulated reduction of azo bond by azo reductase in Remazol red, ii) the same reduction was totally hampered due to presence of ethyl-amino propanenitrile group at para position to azo group in Rubine GFL.
