Novel Lactococcus lactis subsp. lactis LKS49 comprising solubility upon insoluble salts and antifungal activity.

摘要

PURPOSE: Lactococcus lactis subsp. Lactis LKS49 is provided to make insoluble phosphate salts in soil into soluble phosphate ions, soluble magnesium, and calcium ions and to suppress the growth of plant pathogenic fungi. CONSTITUTION: Novel strain Lactococcus lactis subsp. Lactis LKS49 (deposit number KTCT 12087BP) has insoluble salt-solubilizing activity and antifungal activity. A method for promoting the growth of crops and improving soil comprises the step of inoculating the strain into crops or soil and solubilizing the insoluble salts in soil. A method for preparing biocalcium, biophosphate, and biomagnesium comprises the step of inoculating the strains into waste biological resource (oyster shell, bone, sea foods, and fish byproducts). The strain is used for manufacturing nutritional supplements, feed, fertilizer, and cosmetic materials.
