ABSTRACT
Release of untreated effluents into the environment results in soil and water pollution and subsequently reduces the fertility rate of soil. Nature has variety of microbes and their enzymes which can efficiently convert toxic effluents and chemicals into less toxic or beneficial alternatives. Thus, in present study, a bacterial isolate (Priestia flexa CGC) has been isolated, characterized and evaluated for its dye degradation potential. The conditions were optimized and it was observed that P. flexa CGC when inoculated to M1 medium of pH 7.5 containing necessary minimal salts and supplemented with 3% dextrose and meat extract resulted in 92.1% reduction of methylene blue. Furthermore, the effect of treated and untreated dyes on seed germination was also evaluated and it was observed that after treatment seed germination increased. Thus, from present study, it was concluded that P. flexa CGC was an efficient candidate for degradation of toxic dyes to enhance seed germination.
Key words: Synthetic dyes, Priestia flexa, bioremediation, environment pollution
