These days, one of the main contaminants is heavy metals. Although heavy metals are a necessary part of the atmosphere, their concentration has gone to a safer level as a result of disruptions to their natural geochemical cycles. Both natural and man-made processes introduce these metals into the ecosystem. It is possible for heavy metals that possess the characteristic of not being biodegradable or destroyable to go from a highly poisonous state to a less harmful state. It is now crucial to remove toxic metals from the environment in order to improve its health. These metals are removed using a variety of physiochemical techniques, but they are exceedingly expensive and inefficient. These techniques can be greatly replaced by bioremediation, which is less expensive and safe for the environment. This technique extracts the harmful pollution from the contaminated areas by means of bacteria, plants, or other living things. For this reason, mostly bacteria that consume these hazardous metals are chosen. In the current study, we isolated four strains that are resistant to heavy metals from Mohan Nagar Ghaziabad industrial effluent. Ten isolates were first examined at 50 ppm concentrations on plates containing various heavy metal salts, including as Cu+2, Cr+6, Cd+2, and Ni+2. Because of their excellent tolerance to heavy metals, isolates were selected. The findings demonstrate that all four isolates are resistant to the heavy metals found in industrial wastewater; as a result, these isolates are more useful in bioremediation.
