“…Sulphide possibly produced in the reduction of the sulphonate moiety would reduce the bulk phase redox potential. Lie et al [16] reported that a strain of Desulfovibrio utilized some sulphonates as electron acceptor in place of sulphates. Hence it is likely that the dye degradation products such as sulphides might be the cause for the lower ORP in dye containing reactors than the control reactor.…”

The microbial decolourization of Reactive Red 2 (RR2) dye has been studied under anaerobic conditions. Three semicontinuous bioreactors were operated with dye concentrations-R1 (control: 0 mg RR2 l −1 ), R2 (100 mg RR2 l −1 ) and R3 (200 mg RR2 l −1 ). The parameters monitored were, oxidation-reduction potential (ORP), methane production, colour and chemical oxygen demand (COD) removal during the feeding cycles. The oxidation-reduction potential values for the first few days were above −150 mV, which later on decreased to less than −275 mV in all the reactors. Colour removal during the first few days of operation was due to adsorption of dye on to anaerobic biomass. However, under steady state conditions, colour removal was above 76% for both the dye containing reactors and it was due to biologically mediated degradation. Methane production and chemical oxygen demand removal in the control and dye containing reactors were almost the same. Integrated analysis of the monitored parameters indicated that, the primary mechanism of colour removal was adsorption of RR2 on to anaerobic biomass and subsequent degradation. Decolourization rates were found to be first order with respect to dye concentration, although an increase in the influent dye concentration resulted in a decrease in the rate from 0.0074 (g volatile suspended solid, VSS) −1 h −1 (100 mg RR2 l −1 ) to 0.0039 (g VSS) −1 h −1 (200 mg RR2 l −1 ). Based on total methane production no inhibition effect of dyes was observed but total methanogenic activity (TMA) results exhibited inhibition of methanogenesis.

Acidic dye is a dye which is salt of a sulphuric, carboxylic or phenolic organic acid .It is used on wool, other animal fibers and some manufactured fibers. These dyes when disposed into the environment causes pollution and serious irreversible damage to the ecosystem. In the present study various sample is collected from effluent of industry in the Vapi region. Four isolates SP1, SP2, SP3 and SP4 found to be effective decolorizer of Acid Maroon V dye. Among these isolate, SP4 shows maximum decolorization.

“…We found both the anticipated 250-fold increase in specific activity and enzyme reactions in cell-free extracts Laue et al 1997b). The sulfonate moiety was recovered as sulfide (Lie et al 1996;Laue et al 1997b) or sulfate ) when the sulfonate was supplied as electron acceptor or electron donor, respectively.…”

Thiosulfate (S 2 O 3 2-) is a natural product that is widely utilized in natural ecosystems as an electron sink or as an electron donor. However, the major biological source(s) of this thiosulfate is unknown. We present the first report that taurine (2-aminoethanesulfonate), the major mammalian solute, is subject to fermentation. This bacterial fermentation was found to be catalyzed by a new isolate, strain GKNTAU, a strictly anaerobic, gram-positive, motile rod that formed subterminal spores. Thiosulfate was a quantitative fermentation product. The other fermentation products were ammonia and acetate, and all could be formed by cell-free extracts.
