Decolourization of textile effluent by a thermophilic bacteria Anoxybacillus rupiensis

Abstract

Release of coloured textile effluents is undesirable in the aquatic environment as they reduce light penetration, thereby affecting aquatic life and limits utilization of the water media. Microbial remediation is an alternative treatment option available other than the commonly employed physico-chemical methods to treat these toxic effluents. This study investigated the potential of Anoxybacillus rupiensis , a thermophilic bacteria isolated from hot water springs of Maharashtra state of India to decolourize local textile effluent. The results showed 75% decolourization through degradation at 60 o C in eight days proving the thermophilic isolate as a potential candidate for decolourizing the textile effluent.
