Revolutionizing remediation: Unveiling the power of Lysinibacillus sp. in tackling heavy metal stress

Abstract

Increased industrialization has elevated heavy metal pollution in soil. Considering their hazardous impact on the ecosystem, it is important to lower heavy metals concentration from the polluted soil. Standard physicochemical methods for metal remediation are quick, effective, and operational; nevertheless, they come with a high cost and are not appropriate for large contaminated areas. They require a lot of energy, produce a large amount of toxic sludge, are not practical for low metal concentrations, and are not eco-friendly. An effective technique for eradicating hazardous heavy metals from contaminated soil is desperately needed given the state of environmental degradation that exists today. Using microorganisms, particularly bacteria resistant to hazardous metals, is the most economical method known as bioremediation. Owing to the enduring characteristics of heavy metals in polluted soil, inhabitant microorganisms require bioengineering in order to assess an appropriate biotechnical method for the removal and/or detoxification of heavy metals in contaminated soil. Many microorganisms have been reported with the ability to alleviate heavy metals from a contaminated environment; Lysinibacillus being one of them. This review highlights the efficiency of Lysinibacillus in heavy metal remediation and how exactly this genus dealt with metal stress at the cellular level. We have evaluated various studies of bioremediation by this particular genus and also illuminated its plant growth-promoting properties.
