Heavy metals are considered serious environmental pollutants. Industrialization activity has put high
amounts of toxic effluents, containing toxic metals into the environment. Therefore, there is an urgent need for
industrial wastewater treatment. This study aims to lead bioremoval by active Pb-resistance bacterial cells. Only
five bacterial isolates were obtained from industrial wastewater samples. Isolate NDSL2 withstood lead
concentrations, MIC recorded at 180 µg/ml, and selected as the most resistant isolate. By depending on
morphological and molecular characterizations, it was identified as Bacillus amyloliquefaciens MPA 1034 strain.
The optimized conditions for improving Pb-bioremoval efficiency were established. Maximum bioremoval of
lead has been revealed 70% by growing and active bacterial cells after 3 days at pH 7, in the presence of lactose,
sodium nitrate and yeast extract. SEM, EDX and FTIR analysis confirmed Pd uptake in and/or bound on bacterial
cells. Thus, it could be recommended to use Pb-resistance bacterial strain as bioremoval and remediate polluted
industrial effluents.
