Bioremediation of some polycyclic aromatic hydrocarbons (pah) from soil using sphingobium indicum, sphingobium japonicum and stenotrophomonas maltophilia bacterial strains under aerobic conditions

Bioremediation of some polycyclic aromatic hydrocarbons (PAHs) present in soil were studied using bacterial strain under aerobic conditions. PAHs used in this study were Anthracene (Anth), Benzo (a) anthracene (B(a)A), Benzo(a)pyrene (B(a)P). The degradation of selected PAHs was assessed by bioaugmentation process by using Sphingobium indicum, Sphingobium japonicum and Stenotrophomonas maltophilia as bacterial strain and biostimulation proceed by cosubstrate. Effect of various parameters such as temperature, concentration and co substrate were studied. Maximum biodegradation was found at 30 0C for B(a)A, B(a)P and Anth. The percentage of biodegradation was maximum with bacterial strain and co-substrate. Percentage biodegradation was found to be increased with increase in concentration of PAHs.
