The polar regions are home to a variety of microorganisms. These microorganisms have been reported to have developed adaptive methods for survival in extreme conditions and resist varieties of abiotic stress such as heavy metals (HMs). Despite this, very limited studies have been done in bacteria from polar regions than bacteria from non-polar regions. The main aim of this study is to explore microorganisms from polar regions that could tolerate abiotic stress of HMs. In this study, microorganisms from polar areas have been isolated and various bioinformatics tools were used for understanding the genomic features, comparison, and analysis. The wet-lab experiments were performed for the validation where the isolated bacteria were exposed to the abiotic stress of HMs. The genome analysis of all the isolated bacteria showed presence of heavy metal resistance genes. Furthermore, the three isolated bacterial strains showed some ability to tolerate HM at 15°C. This study is very helpful to explore diversity of abiotic stress resistant microorganisms, to monitor environmental health, and to utilize these potential microorganisms for betterment of the environment, agriculture, and ultimately humankind.
