“…have been characterized (Gorbushina et al 2004;Ravikumar et al 2012;Subathra et al 2013). As the catabolic activities of microorganisms in the form of consortia complement each other, obviously syntrophic interaction present in the mixed communities can lead to complete mineralization of the paints (Chang et al 2004). The aim of present study was thus to isolate, identify, and to seek the bioremediation potential of the oilbased-paint-degrading bacterial strains from oil-basedpaint-polluted soil of Khairpur and Sukkur cities of Pakistan.…”

“…Thus, it is experienced that the hazardous pollutant-polluted sites are novel and sources of choice for the isolation of microorganisms carrying out biodegradation and bioremediation. The bacterial degradation of paint is normally faster than the fungi to mineralize the paints through combined metabolic mode of aerobic-anaerobic reaction in the form of consortia (Chang et al 2004). Consequently, different paint-degrading bacterial species belonging to genera Pseudomonas, Micrococcus, Sphingomonas, Thiobacillus, Mycobacterium, Clostridium, Alcaligenes, Bacillus, Flavobacterium, Arthrobacter, Gallionella, Staphylococcus, Gracilibacillus, Salibacillus, Virgibacillus, and Shewanella, etc.…”

Environmental pollution by oil-based paint effluents is of great concern nowadays due to widespread applications of oil-based paints that cause discharge and accidental spillages into the environment. The present study sought to explore the potential use of indigenous bacterial isolates for biodegradation of oil-based paints. The oil-based-paint-biodegrading potential of three Bacillus species isolated from paint-polluted soil samples of different paint warehouses was investigated by the enumeration, screening and taxonomic characterization of oilbased-paint-degrading bacteria using soil enrichment technique in mineral salt medium (MSM). The screened isolates were identified based on morphological, biochemical and 16S rRNA gene sequence homology methods. The bioremediation potential of each bacterial isolate was determined for a period of 14 days at 37°C and 160 rpm in 250-ml shake flask containing 100 ml MSM plus oil paint (final conc. 300 ppm, w/v). The percent removal of oil-based paint was determined against a standard curve of oil-based paint prepared by using UV-Vis spectrophotometer at 285 nm (k Max.). Three bacterial isolates, Bacillus subtilis strain NAP1 (GenBank: KJ872852), B. subtilis strain NAP2 (GenBank: KJ872853) and B. subtilis strain NAP4 (GenBank: KJ872855) were isolated and identified. All the isolated strains were characterized as potential oil-based paint degraders. Maximum oil-based paint removal was recorded with strains NAP1 (66.5 %), followed by NAP2 (61.4 %) and NAP4 (55.9 %). The oil-based-paint-polluted environments are a promising source of oil-based-paint-degrading bacteria. The bacterial isolates of present study offer substantial potential for future environmental applications.

“…Keck et al (2002) proposed that these redox mediators shuttle electrons from the cells to the azo dyes, which results in purely chemical, extremely nonspecific, extracellular reductive cleavage of the azo bond. Chang et al (2004) also reported that extracellular metabolite of Escherichia coli strain NO 3…”

Previous work showed that Enterococcus faecalis ID6017 and Chryseobacterium indologenes ID6016 were able to decolorize the orange II qualitatively. In that experiment, E. faecalis could decolorize orange II more rapidly than C. indologenes. The objective of this study was to examine the decolorization of orange II by mixed culture and the growth of both bacterial species on orange II containing medium. The experiment was done in 500 mL sterilized Erlenmeyer flasks containing 285 mL growth media with 80 mg L-1 orange II. Five different treatments were performed in this project, i.e. medium was inoculated with (i) 15 mL of sterile aquadest, (ii) 15 mL of C. indologenes, (iii) 15 mL of E. faecalis, (iv) 7.5 mL of C. indologenes and 7.5 mL of E. faecalis, and (v) 7.5 mL of E. faecalis until decolorization occured , followed by inoculation with 7.5 mL of C. indologenes. Bacterial growth (total cells number), orange II, glucose, and suphanilic acid, as intermediate product of orange II decolorization, concentrations were measured every 2 h.The maximum decolorization of orange II was observed in the medium inoculated with a mixed culture of E. faecalis and C. indologenes. Decolorization of orange II occurred of growth and gave final concentration of sulphanilic acid of 7.06 mg L-1. During culture both species grow in equilibrium in terms of population

“…The success of the wide use of these dyes is related to their easy synthesis, cost-effectiveness, stability, and great structural variety, which enables a wide range of colors and applications. Thus, in addition to the textile industry, these dyes are widely used in the paper, food, leather, cosmetics, and medical industries (CHANG et al, 2004;TELKE et al, 2008).…”

Biodecolorization of the azo dye Orange G was investigated using a new strain of Candida cylindracea SJL6, isolated from freshwater samples of the Subaé river in Bahia state, Brazil. Strain SJL6 was identified as C. cylindracea on the basis of 26S rDNA region. The various parameters of dye decolorization and cell growth were studied, including the Orange G dye concentration (100 to 500 ppm), temperature (20 to 40 °C), glucose concentration (0 to 5%), and initial pH (3 to 8). Biotoxicity tests were performed using shrimp (Artemia salina) to determine the lethal concentration (LC 50 ) and onion bulbs (Allium cepa) to determine the cytotoxic and genotoxic effects of both Orange G dye and metabolites formed after decolorization. Up to 90% of decolorization of the Orange G dye at 500 ppm was achieved by C. cylindracea SJL6 at 30 °C, pH 3, and 1% glucose. However, the biotoxicity tests showed that there was increased toxicity after decolorization, suggesting partial Orange G dye degradation and production of toxic metabolites.
