“…Various basic and advanced instrumental techniques of chromatography and spectroscopy can be used to isolate and characterize the products of biodegradation of dyes and thus have an insight into the mechanism of biodegradation. To date, very few reports are available on the intermediates or the products of biodegradation of triphenylmethane dyes (Chen et al 2008). The bacterial metabolism of azo dyes is initiated in most cases by a reductive cleavage of the azo bond, which results in the formation of colorless aromatic amines (Khalid et al 2008).…”

“…The microbial toxicity on Azobacter vinelandii, a nitrogen fixing bacterium, showed growth inhibitory zone (1.2 cm) surrounding the well containing dye, while the products did not show inhibitory zone. Chen et al (2008) performed antimicrobial test of crystal violet and its degradation product using E. coli strain JM 109 as model microbe. They used crystal violet solution (100 mg L −1 ) before biodegradation, crystal violet solution after incubation (with Shewanella decolorationis NTOU1) for 11 h (>98% decolorized) and crystal violet solution after incubation for 59 h, for growth of Escherichia coli strain JM 109.…”

The contamination of soils and waters by dye-containing effluents is of environmental concern. Due to the increasing awareness and concern of the global community over the discharge of synthetic dyes into the environment and their persistence there, much attention has been focused on the remediation of these pollutants. Among the current pollution control technologies, biodegradation of synthetic dyes by different microbes is emerging as an effective and promising approach. The bioremediation potentials of many microbes for synthetic dyes have been demonstrated and those of others to be explored in future. The biodegradation of synthetic dyes is an economic, effective, biofriendly, and environmentally benign process. Bioremediation of xenobiotics including synthetic dyes by different microbes will hopefully prove a green solution to the problem of environmental soil and water pollution in future. This review paper discusses comprehensively the science and arts of biodegradation of synthetic dyes.

“…It was found that 15% of triphenylmethane dyes, which are currently manufactured, are lost to waste water as a result of inefficiency in the chemical and physical treatment processes (Chen et al, 2008). Yatome et al (1993) reported that four triphenylmethane dyes (basic fuchsin, methyl violet, crystal violet and Victoria blue) were biodegraded using Pseudomonas pseudomollei 13NA.…”

-Synthetic dyes are widely used in the textile, cosmetic, printing, drug, and food processing industries. Triphenylmethane dyes belong to the most important group of synthetic dyes. They are generally considered as the xenobiotic compounds, which are very recalcitrant to biodegradation. Bacillus sp., was isolated from the treatment plant effluent of a textile and dyeing industry (SITEX) located in Ksar Hellal, Tunisia, decolorizes crystal violet (500 ppm) within 2.5 h under shaking condition at pH 7 and temperature 30 °C. The effect of dye concentration, temperature and initial pH of the solution were studied. The results obtained from the batch experiments revealed the ability of bacteria in removing dye. UV-Vis spectroscopy and FTIR analysis of samples before and after dye decolorization in culture medium confirmed decolorization of crystal violet. The phytotoxicity and microbial toxicity studies of extracted metabolites suggest the less toxic nature of them.

Basic Violet 3 (BV) belongs to the most important group of synthetic colorants and is used extensively in textile industries. It is considered as xenobiotic compound which is recalcitrant to biodegradation. As Candida krusei could not use BV as sole carbon source, experiments were conducted to study the effect of cosubstrates on decolorization of BV in semi synthetic medium using glucose, sucrose, lactose, maltose, yeast extract, peptone, urea and ammonium sulphate. Maximum decolorization (74%) was observed in media supplemented with sucrose. Use of sugarcane bagasse extract as sole nutrient source showed 100% decolorization of BV within 24 h under optimized condition. UV-visible, FTIR spectral analysis and HPLC analysis confirmed the biodegradation of BV. Six degradation products were isolated and identified. We propose the biodegradation pathway for BV which occurs via stepwise reduction and demethylation process to yield mono-, di-, tri-, tetra-, penta- and hexa-demethylated BV species which was degraded completely. The study of the enzymes responsible for decolorization showed the activities of lignin peroxidase, lacasse, tyrosinase, NADH-DCIP reductase, MG reductase and azoreductase in cells before and after decolorization. A significant increase in activities of NADH-DCIP reductase and laccase was observed in the cells after decolorization. The yeast C. krusei could show the ability to decolorize the textile dye BV using inexpensive source like sugarcane bagasse extract for decolorization.
