Solubilization of manganese oxide (MnO2) by manganese solubilizing bacterial (MSB) strains viz. ASH6, ASH11, ASH19, ASH20, and ASH22 on MnO2-amended nutrient agar medium for 48 h; After incubation, dilute iodine solution was flooded on agar medium and appearance of manganese solubilization zone around bacterial growth was considered positive for solubilization of MnO2.
