The pollution of the environment with toxic heavy metals is spreading through the world along with industrial progress. Although, some heavy metals are important and essential trace elements, but at high concentration most of these can be hazardous. Metals are significant toxic factor to biota in the environment for example heavy metals may decrease metabolic activity and diversity as well as affect the quantitative and qualitative structure of microbial communities and cause production of free radicals and cellular damage. Microorganism plays a significant role in bioremediation of heavy metals and biogeochemical cycling of toxic heavy metals. The general ways in which microbes interact with metals as some microbe’s evolved mechanism to detoxify heavy metals; some use them for their respiration. Isolate was selected based on high level of heavy metal and antibiotic resistances. On the basis of morphological, biochemical, 16S rDNA gene sequencing revealed that, the isolates were authentically identified as JNEC/BT/CHA/B3 belongs to genus Pseudomonas. The present embodiment reviews the varied microbial plethora exhibiting resistance against different heavy metals (Hg, Ni, and Cr), antibiotics (ampicillin, amoxicillin) or both. The identified heavy metal resistant bacteria could be useful for the bioremediation of heavy metal contaminated sewage and waste water.
