Abstract
Provided is a lactic acid bacterium capable of homolactic fermentation using a pentose as a substrate, the lactic acid bacterium utilizing a pentose, and in which a phosphoketolase pathway is blocked and a pentose phosphate pathway is activated. Also provided is a method for producing lactic acid from a pentose using the lactic acid bacterium and a method for preparing the lactic acid bacterium.
Claims4
A lactic acid bacterium capable of homolactic fermentation using a pentose as a substrate, the lactic acid bacterium utilizing a pentose, and in which a phosphoketolase pathway is blocked and a pentose phosphate pathway is activated.
A method for preparing a lactic acid bacterium capable of homolactic fermentation using a pentose as a substrate, comprising:
- providing a pentose-utilizing lactic acid bacterium;
- and
- causing a defect in a gene encoding a phosphoketolase in the lactic acid bacterium to block a phosphoketolase pathway.
