“…Pradeep Varma reported on the effect of various temperatures (25 to 50 °C) on decolourization of Ranocid Fast Blue (RFB) and Procion Brilliant Blue-H-GR (PBB-HGR) by Serratia marcescens they have observed faster decolourization at 26 °C within 24 h incubation [24]. In the present study, the optimum temperature for decolourization of mixed dyes by the isolated bacterial strain was found to be 28 °C which showed decolourization up to 94% by the end of 5 th day.…”

The aim of the present study was to isolate an alkaliphilic bacterial strain from textile effluent contaminated site and to investigate the ability of the bacterial strain to decolorize the mixed dyes, Direct Brown MR and Direct Yellow SG at different concentrations. The enriched moderately alkaliphilic bacterial strain could decolorize mixed azodyes (DB MR and DY SG) at different concentrations (50 to 250 mg/L). The bacterial strain exhibited maximum decolourization ability of mixed dyes at pH 9, at a concentration of 150 mg/L (90%) of DB MR and DY SG which showed the maximum degradation of 90% by the end of 5th day, at an optimum temperature at 28 °C. Supplementing the media with sucrose and yeast extract, as carbon and nitrogen source could enhance the dye decolourization efficiency of the isolated bacterial strain. The isolated mixed dye degrading bacterial strain was identified by 16S rRNA sequencing as Serratia marcescens. Such isolated bacterial strain could be applied to biological systems for the effective removal of these mixed dyes from textile effluent wastewater.

Textile dyes accounts for 22 % of total dyes utilization and are potential pollutants due to their toxicity and carcinogenicity. Brown Rot Fungi (BRF) have great potential of biodegradation of dyestuffs due to their efficient nonspecific ligninolytic enzyme system. Current study was conducted for application of indigenous Daedalea dickinsii IEBL-2, a brown rot fungi, to degrade single azo disperse dyes i.e. disperse violet-63 and disperse orange-30. Response Surface Methodology (RSM) with Box Behnken Design was employed to optimized biodegradation process. Ligninolytic enzymes involved in biodegradation were also studied and biodegradation process was monitored by High Performance Liquid Chromatography (HPLC). There was 72.14±1.1% and 68.71±1.04% biodegradation observed after screening experiments for dye-1 and dye-2. Optimization by RSM at step-1 increases biodegradation to 80.83±1.35% and 78.3±1.16% and after step-2, 88.93±1.32% and 93.32±1.54% respectively. Study of ligninolytic enzymes i.e manganese peroxidase, lignin peroxidase and laccase revealed their involvement in biodegradation process. HPLC analysis confirmed the biodegradation process and conversion of complex dyes into simple secondary amines i.e diphenylamine and 3-methyldiphenylamine. These findings would help to reduce the environmental pollution by textile effluent and also reduces the risk of certain diseases.

“…Microorganisms use carbon and nitrogen as source of energy and lead to biodegradation of synthetic dyes. Klebsiella and Bacillus have been found to use glucose, starch, sucrose and yeast extract as carbon source and peptone as nitrogen source resulting in degradation of Turquoise blue and Malachite green dyes (Joshi et al, 2013;Ramezani et al, 2013).…”

Bivalves are common marine species which are used as bio-indicators. These organisms are filter feeders and have a tendency to accumulate heavy metals and organic pollutants from sea water in their tissue. Their gills host microorganisms, which are also exposed to the heavy metals and other pollutants. The objective of the present study was to isolate and characterize these microorganisms and explore their potential for bioremediation of polluted waters. Eight different microbial cultures were isolated from edible clams (bivalve molluscs) collected from the coast of Mumbai and Alibaug. Biochemical and morphological tests were performed to characterize the isolated bacteria. All the eight cultures showed growth in 8% NaCl solution indicating that they are halotolerant. Gradient plate method was used to test resistance of the isolates to three dyes commonly used for painting of idols-Fluoorange, Fluo green and Fluo blue and Malachite green. The isolates were also tested for metal resistance against Zn, Cu, Co and Pb using agar cup method. It was observed that six isolates (AS1, AS3, MS3, MS4, MS9, MS11) were resistant to the three selected dyes while two isolates (AS2, MS1) were sensitive. AS1, AS3, MS9 and MS11 were found to be resistant to Malachite green up to 0.01 mg/ml. MS11, identified as Staphylococcus arlettae, showed the highest tolerance to metals-up to 80 mM of ZnSO 4 , CuSO 4 , CoCl 2 and PbNO 3. For the other isolates the resistance to metals was variable; MS4 was found to be most sensitive. The results suggest that the isolated bacteria, Staphylococcus arlettae, from bivalves has resistance to toxic chemicals and may find application in bioremediation processes.
