A high exhaust reactive dye, Green HE4B (GHE4B) was 98% degraded in nutrient medium by Pseudomonas desmolyticum NCIM 2112 (pd2112) within 72 h at static condition. Decolorization time in synthetic 10 g/l molasses. Addition of 5 g/l peptone to NaCl medium had reduced decolorization time from 108 to 72 h. Beef extract do not contribute more to the inducing effect of peptone, however it is a good co-substrate in sucrose or urea containing NaCl medium. Intracellular lignin peroxidase (Lip), laccase and tyrosinase activities were induced by 150, 355 and 212%, respectively till maximum dye removal took place. Aminopyrine N-demethylase (AND) and dichlorophenol indophenol reductase (DCIPreductase) activities in pd2112 were induced by 130 and 20%, respectively at 72 h of incubation during GHE4B decolorization. By high performance liquid chromatography (HPLC) analysis, 4-hydroxybenzene sulfonic acid and 4-amino, 6-hydroxynaphthalene 2-sulfonic acids incubation. Fourier transform infrared spectroscopy (FTIR) analysis supports the formation of these aromatic amines. pd2112, aerobically degraded GHE4B metabolites (formed at static condition) showing stationary phase of 6 days. There was no germination inhibition of Sorghum bicolor and Triticum aestivum by GHE4B metabolites at 3,000 ppm concentration however untreated dye showed germination inhibition at the same concentration. GHE4B metabolites did not show any microbial toxicity at 10,000 ppm concentration.

“…laccase는 목질분해 뿐만 아니 라 페놀계 염료의 탈색에 매우 유용하게 이용되고 있다. 세 계적으로 연간 700,000 톤 이상의 염료가 생산되고 있으며 (Moosvi et al, 2007), 합성염료인 azo, anthraquinone, triphenylmethane과 phthalocyanine 계통의 염료는 섬유산 업에서 사용량이 지속적으로 증가하고 있다. 염료의 종류 에 따라 2-50%의 염료가 섬유와 결합하지 않고 주변의 토양이나 바다에 폐수로 유실되어 환경오염의 원인이 된 다 (Ganesh et al, 1994;O' Neill et al, 1999).…”

“…SUK1 bacterium when compared with its constituent pure strains (Lade et al 2012). It is suggested that in microbial consortium the individual strains may attack dye molecule at different positions or may utilize the metabolites produced by co-existing strains for further decomposition which results in increased rate of decolorization than single strains (Moosvi et al 2007). …”

Abstract:In the present study, the enrichment and isolation of textile effl uent decolorizing bacteria were carried out in wheat bran (WB) medium. The isolated bacterium Providencia rettgeri strain HSL1 was then tested for decolorization of textile effl uent in consortium with a dyestuff degrading fungus Aspergillus ochraceus NCIM 1146. Decolorization study suggests that A. ochraceus NCIM 1146 and P. rettgeri strain HSL1 alone re moves only 6 and 32% of textile effl uent American Dye Manufacturing Institute respectively in 30 h at 30 ±0.2°C of microaerophilic incubation, while the fungal-bacterial consortium does 92% ADMI removal within the same time period. The fungal-bacterial consortium exhibited enhanced decolorization rate due to the induction in activities of catalytic enzymes laccase (196%), lignin peroxidase (77%), azoreductase (80%) and NADH-DCIP reductase (84%). The HPLC analysis confi rmed the biodegradation of textile effl uent into various metabolites. Detoxifi cation studies of textile effl uent before and after treatment with fungal-bacterial consortium revealed reduced toxicity of degradation metabolites. The effi cient degradation and detoxifi cation by fungal-bacterial consortium pre-grown in agricultural based medium thus suggest a promising approach in designing low-cost treatment technologies for textile effl uent.
