Antibiotic and heavy metal tolerance of some indigenous bacteria isolated from petroleum contaminated soil sediments with a study of their aromatic hydrocarbon degradation potential

This article presents a study of the bacteria bioremediation characters and their heavy metal and antibiotic tolerance from the petroleum contaminated soil located in industrialized areas of Chhattisgarh, India. Soil sediments were characterized by FTIR for the presence of aromatic compounds and further the heterotrophic and fuel degrader counts was estimated. The strains characterized were predominantly from the Bacillus species which showed mixed resistance patterns against antibiotics and heavy metals. The present study results revealed that isolates Aneurinibacillus migulanus strain KTPP was most potent in degrading all the hydrocarbons and showed multiple resistance against heavy metals.
