“…from activated sludge treating domestic and industrial wastewaters and (Lauff et al 1993;Dangmann et al 1996;White et al 1996). Strains of A. radiobacter appear to be the most frequently reported ones (Drysdale et al 1999;Singh et al 2004). A. radiobacter (strain S2) reported by Feigel and Knackmuss (1993) could not grow on 4-ABS as growth substrate.…”

A bacterial strain, PNS-1, isolated from activated sludge, could utilize sulphanilic acid (4-ABS) as the sole organic carbon and energy source under aerobic conditions. Determination and comparison of 16S r DNA sequences showed that the strain PNS-1 is closely related to the species of Agrobacterium genus. Growth on 4-ABS was accompanied with ammonia and sulfate release. TOC results showed complete mineralization of sulphanilic acid. This strain was highly specific for 4-ABS as none of the sulphonated aromatics used in the present study including other ABS isomers were utilized. Strain PNS-1 could, however, utilize all the tested monocyclic aromatic compounds devoid of a sulfonate group. No intermediates could be detected either in the growth phase or with dense cell suspensions. Presence of chloramphenicol completely inhibited 4-ABS degradation by cells pregrown on succinate, indicating that degradation enzymes are inducible. No plasmid could be detected in the Agrobacterium sp. Strain PNS-1 suggesting that 4-ABS degradative genes may be chromosomal encoded.

“…Tan et al (2005) have reported that their enrichment culture could utilize both 2-and 4-ABS, but not 3-ABS. There are few reports on 4-ABS degradation by co-culture as well as pure cultures (Feigel and Knackmuss 1993;Perei et al 2000;Singh et al 2004). These cultures could utilize only 4-ABS and not other benzene sulfonates, although they could grow on many other simple aromatic compounds.…”

“…During the last two decades, mixed cultures as well as a few pure bacterial strains, which can utilize aminoarylsulfonates as sole carbon and energy sources, have been isolated (Nortemann et al 1986;Thurnheer et al 1986;Locher et al 1989;Rozgaj and Glancer 1992;Stolz 1999). Among the three isomers of aminobenzenesulfonate (ABS), 4-ABS is the most susceptible for biodegradation (Fiegel and Knackmuss 1988;Perei et al 2000;Coughlin et al 2002;Singh et al 2004). As per our knowledge, there is only one report on 2-ABS degrading pure culture, which is identified as Alcaligenes sp.…”

A variety of environmental inocula were tested for the development of 2-aminobenzenesulfonate (2-ABS, Orthanilic acid) degrading bacterial enrichment. A bacterial consortium (BC), which could utilize 2-ABS as the sole carbon and energy source, could only be developed from the sludge derived from a wastewater treatment unit of a large chemical industry manufacturing nitro and aminoaromatics. BC consisted of two bacterial strains. Based on 16S rDNA sequence analysis, these strains were identified to be belonging to the genus, Acinetobacter and Flavobacterium. The consortium could degrade 1,000 mg l -1 2-ABS within 40 h. Evidence for the extensive mineralization of 2-ABS, during the growth of BC, was derived from U.V-spectral and total organic carbon analysis. BC was highly specific for 2-ABS, as other benzene sulfonates tested in this study, including other ABS isomers, were not utilized as growth substrates. 2-ABS removal pattern in the presence of glucose was significantly influenced by acclimation characteristics of the culture. Consortium adapted to 2-ABS/glucose demonstrated the concomitant removal of both substrates, whereas glucose exerted catabolic repression on 2-ABS removal with glucose adapted culture. Presence of chloramphenicol inhibited 2-ABS degradation by cells, pregrown on succinate, indicating that the 2-ABS degrading enzymes are inducible in nature. Thus the presence of 2-ABS is essential for maintaining the high degradation potential. This enrichment culture can find an application in the treatment of 2-ABS containing wastewaters.

“…Physico-chemical treatment methods are the least desirable owing to their high costs and generation of secondary pollutants. On the other hand, biological treatment methods are attractive due to their cost effectiveness, diverse metabolic pathways and versatility of microorganisms Singh et al 2004;Mendez-Paz et al 2005; Van der Zee and Villaverde 2005; Pandey et al 2007). Among the anaerobic processes, Upflow Anaerobic Sludge Blanket (UASB) reactor has been widely used to treat variety of industrial and domestic wastewaters all over the world.…”

The discharge of textile wastewater containing dye in the environment is varying for both toxicology and esthetical reasons as dyes impede light penetration, damage the quality of the receiving streams. Upflow anaerobic sludge blanket reactor with anaerobic digester sludge treating starch wastewater has been used to investigate the removal efficiency of chemical oxygen demand (COD) and colour of textile dye wastewater. In this study, the starch and textile dye wastewater was mixed at 70 and 30%, respectively, and the experiments were carried out with recycle of treated wastewater at different percentage as 10, 20, 30 and 40. Maximum removal of COD and colour was 96% and 93.3%, respectively, at 30% recycle. At various OLR and HRT, the maximum removal of COD, colour was 95.9%, 93% at 6.81 kg COD/m 3 d and 96%, 93% with 24 h of HRT. The maximum production of biogas at 24 h of HRT with 30% recycle was about 355 l/d. The Volatile fatty acid/Alkalinity ratio of methanogenic reactor was found to be 0.049-0.053. The result provided evidence, the starch and dye wastewater have wide variation in their characteristics was treated on combination, this new technology supports the effective utilization of starch waste in destruction of dye.
