  • Publication number: 20210403882
    Abstract: Disclosed are a recombinant acid-resistant yeast having improved lactic-acid-producing ability and a method of preparing lactic acid using the same. When producing lactic acid using the recombinant acid-resistant yeast according to the present invention, not only lactic-acid fermentation can be performed with lactic-acid-producing ability similar to that of bacterial fermentation using a remarkably smaller amount of a neutralizing agent than in the case of conventional bacterial fermentation, but also the production of ethanol and glycerol which are byproducts can be reduced. Thus, fermentation costs can be greatly reduced and the cost of subsequent purification processes can be reduced.

  • Publication number: 20210324346
    Abstract: Disclosed are a recombinant acid-resistant yeast having lactic acid-producing ability and suppressed glycerol production and a method of preparing lactic acid using the same. More particularly, disclosed are a recombinant acid-resistant yeast into which a gene involved in lactic acid production is introduced and in which a gene involved in glycerol production is deleted or attenuated, and a method of preparing lactic acid using the same. When producing lactic acid using the recombinant acid-resistant yeast, the production of lactic acid is maintained while the production of glycerol is reduced, so crosslinking by glycerol can be suppressed in the oligomerization reaction for conversion to lactide, and thus the conversion yield of lactic acid to lactide can be increased.
