DNA ENCODING PROTEIN THAT TAKES PART IN TREHALOSE SYNTHESIS (VARIANTS) AND METHOD FOR PREPARING L-GLUTAMIC ACID (VARIANTS) Russian patent published in 2006 - IPC C12N15/11 C12N15/63 C12N1/21 C12P13/14 C12R1/15

Abstract RU 2276189 C2

FIELD: biotechnology, biochemistry, amino acids.

SUBSTANCE: L-glutamic acid is produced in culturing corynebacterium possessing ability to produce L-glutamic acid. This microorganism shows reduced ability for synthesis of trehalose or its absence as result of destruction of gene encoding trehalose-6-phosphate synthase, or gene encoding maltooligolysyltrehalose synthase, or by addition of mutations in these genes. Invention provides preparing L-glutamic acid with high degree of effectiveness.

EFFECT: improved method and enhanced effectiveness for preparing amino acid.
