Isolation, Identification and Characterization of Heavy Metal Bacterial Communities from Sewage

This study explores the diversity of microbes in drainage wastewater. The present study deals with isolation, identification and characterization of heavy metal resistant bacteria was isolated from sewage water collected from boys and girls hostels in Yogi Vemana University, Kadapa, Andhra Pradesh, India. The six isolates were isolated and selected based on high level metal resistance. On the basis of morphological, biochemical, 16S rRNA gene sequencing and phylogeny analysis revealed that, the isolate was authentically identified as Bacillus psedomycoides-MH578628.1 with the percentage identity 98.86. The sewage isolates showed optimum growth at 30⁰C and pH 7.0. The identified isolates were resistant to heavy metals in collected sewage water like iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), cadmium (Cd), lead (Pb), and silver (Ag). The identified heavy metal resistant bacteria could be useful for the bioremediation of heavy metal contaminated sewage and waste water.
