Zn-Mobil is produced from a beneficial autotrophic and acidophilic bacterium Thiobacillus thiooxidans. Zinc (Zn) is one of the essential micronutrients required for optimum plant growth. Substantial quantity of applied inorganic zinc in soil is converted into unavailable form. Zinc solubilizing bacteria are potential alternates for zinc supplement. Zinc deficiency in plants leads to reduced membrane integrity and synthesis of carbohydrates, auxins, nucleotides, cytochromes, and chlorophyll and develops susceptibility to heat stress.
