Abstract

Surfactants are organic chemicals that reduce surface tension in liquids. Surfactants are broadly used industrially and in households, the effluent let out in river water is toxic and there is anticipation of alarming consequences to aquatic organisms. To counter-balance its appalling repercussions, microbial degradation offers a competent approach. For the purpose bacteria were isolated from spumes as they are potent surfactant degraders. Samples were collected from Arabian Sea & Indian Ocean during tides and were analyzed. Samples were enriched in Zobell Marine Broth and were then screened for surfactant degradation using basal medium consisting SDS & Nirma as sole carbon source. Eight bacterial strains were isolated (S1, S2, S3, S4, S5, N1, N2, N3), all tested strains were gram positive, motile except S4, aerobic, rod and cocci, oxidase positive except S4, and requires sodium for growth except strain N1. Best degradation was observed at room temperature, in alkaline conditions after 72hours incubation, maximum degradation efficiency was obtained with strain S1 & S3 -14% and N1-17% using MBAS assay. Better degradation was observed with consortium 16% for SDS degraders and 19% for Nirma degraders. Varying substrate concentrations were used, Nirma degradation was observed at 0.5% and 1% concentration and SDS degradation was observed only with 1% concentration. Finally textile washing effluent was treated and 100% surfactant degradation was observed using consortia, also the dye contained in effluent was degraded which was confirmed by azo reductase activity. The bioremediation of surfactants along with dyes was also seconded by FTIR (Fourier-transform infrared spectroscopy).
