Enhanced degradation of indeno(1,2,3-cd)pyrene using Candida tropicalis NN4 in presence of iron nanoparticles and produced biosurfactant: a statistical approach.

ABSTRACT: Seven yeast isolates were screened for the remediation of indeno(1,2,3-cd)pyrene (InP) using biosynthesized iron nanoparticles and produced biosurfactant in growth medium. Four yeast isolates showed positive response to produce biosurfactant which was confirmed by drop collapse test, emulsification index, methylene blue agar plate method, oil displacement test and lipase activity. The yeast strain showing maximum potential for InP degradation and biosurfactant production was identified as Candida tropicalis NN4. The produced biosurfactant was characterized as sophorolipid type through TLC and FTIR analysis. Iron nanoparticles were biosynthesized using mint leaf extract and characterized by various instrumental analysis. Response surface methodology (RSM), three-level five-variable B
