Cadmium (Cd), one of the heavy metals, is known to be a widespread environmental contaminant and potent toxin that can harm human health. Heavy metal pollution has become a major international issue. Using cadmium-resistant bacterial strains isolated from a Bassein creek water sample, this study set out to develop a practical strategy for attempting to eliminate cadmium from the environment. A contaminated water sample from Vasai Creek, formerly Bassein Creek, an estuary and one of the two main Ulhas River distributaries in the Konkan division of Maharashtra, India, was used to isolate eight cadmium-resistant bacterial strains for this study. Two of these isolates, designated C1 and C6, were found to be tolerant of cadmium contamination and to thrive in the laboratory. The minimal inhibitory concentration, which ranged from 50 to 1000 ppm, was also used to screen these bacterial isolates for metal resistance to Cd2+. C1 was found to be tolerant of Cadmium levels up to 200 ppm, while C6 was found to be tolerant of Cadmium levels up to 400 ppm. In addition, a study using an atomic absorption spectrophotometer (AAS) revealed that both strains (C1 and C6) were able to significantly absorb and remove 96.15% and 96.08% of Cadmium within five days, respectively. The obtained isolates may be Micrococcus or Arthrobacter sp., according to the biochemical tests. As a consequence of this, the study demonstrated that the bacterial strains C1 and C6 can be actively utilized for the bioremediation of heavy metals like cadmium, a significant toxic pollutant that is present in industrial events. Chemical precipitation, solvent recovery, and other conventional approaches have a number of drawbacks, including the production of toxic sludge and the unpredictable removal of metal ions. Therefore, the removal or detoxification of heavy metals primarily from soil, water, and sediments can be effectively accomplished through microbial remediation using these two strains of bacteria.
