Methylobacterium extorquens and method for producing lactic acid using same

Abstract

A Methylobacterium extorquens and a method for producing lactic acid using the same is provide. The Methylobacterium extorquens is capable of fermenting methanol to produce lactic acid. The lactic acid production method comprises the following steps: (a) providing Methylobacterium extorquens that can ferment methanol to produce lactic acid; (b) inoculating the Methylobacterium extorquens into a methanol culture medium containing methanol at a concentration of below 2% v/v, the methanol culture medium has a C/N ratio value of 3.5 to 21 and a pH value of pH 4 to pH 9; and (c) allowing the Methylobacterium extorquens to ferment the methanol in the methanol culture medium to produce lactic acid under 20° C. to 30° C. Through the above Methylobacterium extorquens and lactic acid production method, a method for producing lactic acid using non-crop materials is provided.
