This study was focused to isolate the most efficient bacteria from heavy metal contaminated soil from Ludhiana, Punjab. A total of 14 microbial isolates were characterized and out of 14, IS1 and IS14 were observed to be most effective because of their high relative growth and resistance against heavy metals. Further, these two isolates were assessed for their ability to remove Zinc and Lead from medium amended with heavy metals. IS1, Bacillus thuringiensis strain “Simi” (Accession number KF 916618.1) was found to be more effective as compared to IS14, Bacillus subtilis strain PSB (Accession number KF 279045.1) for the remediation of heavy metals. IS1 showed mean of 54% biodegradation efficacy in the first three days and from day 4 on wards the mean percentage of biodegradation efficacy decreased to around 31%. The results of the present study showed that the metal resistant bacteria can be used for heavy metal bio accumulation.
