Abstract

The present invention provides four keto acid transporter encoding sequences selected from 6611 protein coding sequences ofCLIB122 database. Also provided are recombinantstrains overexpressing the keto acid transporters, which have increased extracellular secretion of α-ketoglutarate. The present invention can be used to increase extracellular levels of α-ketoglutarate during the fermentation process and lower downstream purification cost for α-ketoglutarate production.
