Abstract
The present invention provides novel microorganisms, Brevibacterium lactofermentum CJJA21 (Accession No. KCCM-10222), which is resistant to sodium azide, and Brevibacterium lactofermentum CJJA22 (Accession No. KCCM-10223), which is resistant to α-aminobutyric acid. These microorganisms are capable of producing L-glutamine in a higher yield than the known strains. The present invention further provides processes for producing L-glutamine using the microorganisms of the invention.
