Title:
SPOROLACTOBACILLUS TERRAE AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/106627
Kind Code:
A1
Abstract:
Provided are sporolactobacillus terrae (sporolactobacillus terrae) HKM-1s with collection numbers CCTCCNO: M2013389 and DSMNo.27555, and a method for producing D-lactic acid therefrom by means of fermentation of the same. The sporolactobacillus terrae HKM-1s can be used for producing D-lactic acid by using a nitrogen source, namely, dry powder of corn steep liquor; the highest fermentation yield of the D-lactic acid is 197g/L, the corresponding fermentation period is 47h, and the fermentation production capacity reaches 4.19g/L/h, and the optical purity of the produced D-lactic acid is 99.9%.
