“…This is also expected as selective media was used for the purpose. Immobilization of the consortium: Immobilization of living microorganisms and enzymes has been described by several investigators (Nasratun et al, 2009;Salemi, 2010;Yusilawati et al, 2010;Fedorak et al, 1985;Friday and Portier, 1991;Durham et al, 1994b) as being useful not only for the production of chemicals for industrial use but also for degradation of chemical pollutants by bacteria where they colonize on the immobilized surface and form biofilms. They are also found to be advantageous over suspended-cell growth (Friday and Portier, 1991;Durham et al, 1994a;1994b;Shimp and Pfaender, 1982;Ehrhardt and Rehm, 1985) for bioremedial purpose.…”

Problem statement: Soluble sulfate load in effluent is a crucial problem from mining industries. The study involved isolation of efficient Sulfate Reducing Bacterial (SRB) consortium from hot water spring for bioremediatrion of sulfate contaminated waste water. Approach: The enriched bacterial consortium was isolated in medium DSMZ 16695. The sulfate reduction efficiency was measured by turbidometric method. The K m and R max value of the consortium was determined. It was immobilized in 10L bioreactor and the sulfate reduction was measured in presence of media and mine effluent. Results: The consortium was found to reduce 2000ppm of sulfate in 36h under optimum condition. The K m of 1.1530 ppm and R max value of 0.030h −1 was obtained under optimum conditions of pH-7.5 at 40°C with 2% inoculum. Consortium immobilized under ambient condition in a 10L packed bed reactor yielded about 21-41% reduction of soluble sulfate in synthetic medium prepared using effluent water and tap water respectively. Conclusion: This study reports for the first time the use of efficient SRB consortia from hot water spring for bioremediation of mine effluent.

“…Immobilized-cell bioreactor technology utilizes the colonization of specialized microorganisms onto inorganic surfaces as fixed films for the degradation of chemical pollutants in environmentally controlled bioreactors (3,7,8). The advantages of this technology over conventional suspended-cell growth systems are well documented (3,6,8,9,14).…”

“…The Type Z biocarrier, however, does not provide adequate protection from toxic organic shock loads. The adsorptive properties of granular activated carbon (GAC), on the other hand, have been demonstrated to protect immobilized microorganisms from excessive fluctuations in concentrations of organic compounds (5)(6)(7)9). In addition, GAC has been shown to enhance biodegradation of low-strength wastes by concentrating the organic compounds at the liquid-solid interface (11,15) and to adsorb inhibitory or recalcitrant compounds (5, 10).…”
