Abstract: The present invention relates to a method for producing lactic acid with high concentration and high yield using Lactobacillus paracasei CJLA0310 KCCM-10542 that is separated and identified from Kimchi. Lactic acid is a very important organic acid with a wide range of applications including food additive such as food preservative, condiment or acidifier, and industrial fields such as cosmetics, chemistry, metals, electronics, fabrics, dyeing textiles, and pharmaceutical industries. Particularly, lactic acid is an essential ingredient of polylactic acid, one of biodegradable plastics to replace recalcitrant non-biodegradable plastics which are main causes of environmental contamination.

Abstract: The present invention relates to an L-arginine producing mutant strain, and a method for fabricating the same. In particular, the present invention relates to a polynucleotide comprising an argD2 gene (Ncgl2355) that is a putative gene of acetylornithine aminotransferase involved in arginine biosynthesis of Corynebacterium glutamicum, a polypeptide encoded by the polynucleotide, a recombinant vector comprising the polynucleotide, a transformant capable of producing L-arginine in a high yield, which is prepared by introducing the recombinant vector into an L-arginine producing host microorganism to overexpress the argD2 gene, and a method for producing L-arginine by culturing the transformant. The transformant of the present invention overexpresses the argD2 gene to produce L-arginine in a high yield, thereby being used in medicinal and pharmaceutical industries.
