Abstract

The invention relates to a lactic acid producing strain and a method for producing lactic acid through the lactic acid producing strain. When the lactic acid is produced through the lactic acid producing strain namely pediococcus acidilactici Pa-COT, the lactic acid production speed is significantly increased, namely that the lactic acid producing strain Pa-COT can significantly increase the lactic acid production property during lactic acid production. Accordingly, when the lactic acid is produced through fermentation of the lactic acid producing strain Pa-COT, the production of the lactic acid can be greatly improved. Besides, the lactic acid producing strain Pa-COT further has the advantages of being low in fermentation cost and environmental-friendly. In addition, the lactic acid producing strain Pa-COT disclosed by the invention further has the following advantages that the lactic acid can be produced through normal fermentation at the fermentation temperature of 45-50 DEG C, thelactic acid producing strain has very good adaptability to a lignocellulose system and can bear stayers generated in the high-concentration preprocessing process, and lactic acid fermentation can be performed by using lignocellulose as a raw material.

Description

Technical field

[0001] The invention relates to the field of microbial fermentation. Specifically, the present invention relates to a strain of Pediococcus lactis that is highly resistant and can use various carbon sources to ferment to produce lactic acid, and a method for producing lactic acid using the strain of Pediococcus lactis. Background technique

[0002] Polylactic acid (PLA) is a biodegradable polymer formed by condensation polymerization of lactic acid monomers. Because its raw materials are renewable biological resources, PLA has been unanimously recognized by the industry as the most promising new "bio-based material" in the new century. In addition, the products made of PLA have good gloss, transparency, hand feeling and heat resistance, and also have certain bacteria resistance, flame retardancy and UV resistance, and have high gloss and processing performance; PLA also It has the characteristics of non-toxic, non-irritating and good biocompatibility. Therefore...
