RHIZODEGRADATION OF PHENANTHRENE, ANTHRACENE AND PYRENE BY AUGMENTING BACILLUS CEREUS AND BACILLUS SUBTILIS STRAINS

Rhizodegradation is one of the best methods for effective removal dangerous polycyclic aromatic hydrocarbons pollutants from soil. This operative due to high persistent, non-bioavailability nature PAHs and combined, sequential reactions bacteria present in rhizosphere plants. We have conducted pot-culture method study degradation three compounds namely phenanthrene, anthracene pyrene artificially contaminated soils non-rhizosphere soil treatments blackgram(Vignamungo L.) that augmented by two potential degraders Bacillus cereus CPOU13 subtilis SPC14 isolated naturally 90days. HPLC studies revealed percentages were more where selected strains over non-augmented soils. The recorded non-augmented. Pyrene, a molecular weight degraded maximum 96.24% treatment with while moderate non-autoclaved contain natural microbial communities. counting bacterial populations during experimental period other gradually increased first day, reached 60days became almost consistent 90days all treatments. It was also observed compared With these results it has been predicted closely associated increasing degrading may consume quantity their metabolic activities Key words: Rhizodegradation, PAHs, HPLC, pot culture.
