Studied on the Bioremediation Effect of Some Selected Microbes on Domestic Sewage Water

Abstract

Bioremediation involves the use of microbes in controlled conditions to degrade various harmful substances in soil and water. In the proposed work, five species of micro-organisms were used to analyse their impact on various physico-chemical parameters of sewage waste water. In the first stage, the actual physicochemical parameters of the collected sample water were recorded (Fresh sample parameters). Following this, the sample water was inoculated with selected micro-organisms (one at a time). The growth of the microbes was observed carefully over a period of 72 hours after inoculation. The physico-chemical parameters were recorded again and were compared with the fresh sample parameters. The results were analysed for any change and on this basis, an impact factor was developed to analyse the extent of remediation effect. The study reveals that Rhodobacter is a very effective microbe in detoxifying organic matter in the sewage water and improving water quality.
