Isolation and characterization of Zinc solubilizing bacteria from Bhitarkanika mangrove forest of Odisha, India

Zinc is a crucial element for optimal plant growth. Some bacteria that solubilize zinc are potential substitutes for zinc supplements because they transform applied inorganic zinc into usable forms. As zinc cannot be produced by the plants by themselves, bacteria play important role in growth increasing of plants by providing zinc. This investigation was done to examine the potential of zinc-solubilizing bacteria isolated from mangrove forests of Odisha. In this study, seven zinc solubilizing bacteria (ZSB) were isolated, of which ZSB2 was found to have maximum zinc solubilizing efficiency of 111.51% on solid medium and solubilizes 6.55 mg/L of Zn in liquid medium. The bacterium was identified as Enterobacter kobei by 16S r-RNA sequencing. Along with zinc solubilization, some ZSB isolates showed positive response towards siderophore production. The study bears significance for application in plant growth promotion.
