Functional Microbial Diversity and Bactorial Flora in Common Effluent Treatment plants of South Gujarat and their Application

Abstract

Centralized industrial wastewater treatment processes encounter intense issues for removal of complex, toxic and refractory compounds present due to variety of industries providing effluents to them. Development of robust bioremediation process of such compounds at large working scale is a challenge. Conventionally developed organisms screened for good bioremediation potential in lab face major failures due to organism s inability to survive in competitive environment of industrial effluents and inefficient scale up of bioprocess. As native microbial community is sustaining in effluent throughout treatment process of common industrial effluents it was hypothesized to look for bioremediation solution into them. This study was aimed to understand the metabolic capacities of wastewater microbial communities using substrate level physiological profiling. Using similarity analysis, it focused on isolating and screening of the most abundant bacteria having capability of hydrocarbon degradation and high survival rates. This study targeted statistical optimization of bioremediation process and scale up to achieve field level application. newline
