Zinc (Zn) is among the essential micronutrients required for optimum plant growth. Inorganic zinc in soil is generally in unavailable form for plant assimilation. However, Zinc Solubilizing Bacteria (ZSB) makes the inorganic zinc in to biologically available form. Such studies in mangroves habitats are almost non-existing. Hence, the present study explored the presence of ZSB from mangrove soil. The ZSB were in a range of 9.53% to 13.9% in non-mangrove soil and Rhizophora mangrove root soil respectively. Out of 24 morphologically distinct strains of ZSB, three strains (ZSB-4, ZSB-13, ZSB-14) displayed high Zn solubilization efficiency on solid medium amended with ZnO (382%), ZnCO3 (365%) and ZnSO4 (336%). These strains exhibited significant release of Zn at the concentrations of 2.3 2.12 and 2.09 ppm by ZSB-14, ZSB-4 and ZSB-13 respectively on 10th day of incubation in broth medium amended with ZnO. The strains released acids as evident by decline in pH of the broth medium. They also secreted IAA with the maximum of 14.5 ppm by ZSB-4 with ZnO as source of Zn. The potential strains for Zn solubilization were identified using 16S rRNA as Pseudomonas aeroginosa for further application as bioinoculants to mangrove soil.
