Title (EN) METHOD FOR PRODUCING LACTIC ACID FROM PLANT-DERIVED RAW MATERIAL, AND LACTIC-ACID-PRODUCING BACTERIUM
(FR) PROCÉDÉ POUR LA FABRICATION D'ACIDE LACTIQUE À PARTIR D'UNE MATIÈRE PREMIÈRE D'ORIGINE VÉGÉTALE ET D’UNE BACTÉRIE PRODUISANT DE L'ACIDE LACTIQUE
(JA) 植物由来原料から乳酸を生産する方法及び乳酸生産細菌
Abstract: front page image
(EN)Disclosed is a lactic-acid-producing Escherichia coli which has at least one gene including at least a sucrose hydrolase gene and selected from sucrose non-PTS genes (provided that a combination of a repressor protein (cscR), a sucrose hydrolase (cscA), a fructokinase (cscK) and a sucrose permease (cscB) and a combination of a sucrose hydrolase (cscA), a fructokinase (cscK) and a sucrose permease (cscB) are excluded) and is genetically so modified as to have a system for enhancing the production of lactic acid.  Also disclosed is a method for producing lactic acid from a plant-derived sucrose-containing raw material by using the lactic-acid-producing Escherichia coli.
(FR)L'invention porte sur une Escherichia coli produisant de l'acide lactique qui a au moins un gène comprenant au moins un gène de saccharose hydrolase et choisi parmi les gènes de systèmes non-PTS d'utilisation du saccharose (à condition qu'une combinaison d'un répresseur (cscR), d'une saccharose hydrolase (cscA), d'une fructokinase (cscK) et d'une saccharose perméase (cscB) et une combinaison d'une saccharose hydrolase (cscA), d'une fructokinase (cscK) et d'une saccharose perméase (cscB) soient exclues) et qui est génétiquement modifiée de façon à avoir un système pour amplifier la production d'acide lactique. L'invention porte également sur un procédé pour la fabrication d'acide lactique à partir d'une matière première contenant du saccharose d'origine végétale à l'aide de l'Escherichia coli produisant de l'acide lactique.
(JA) 本発明は、スクロース非PTS遺伝子群のうちスクロース加水分解酵素遺伝子を少なくとも含む1種以上の遺伝子(ただし、リプレッサー蛋白質(cscR)、スクロース加水分解酵素(cscA)、フルクトキナーゼ(cscK)及びスクロース透過酵素(cscB)の組み合わせと、スクロース加水分解酵素(cscA)、フルクトキナーゼ(cscK)及びスクロース透過酵素(cscB)の組み合わせとを除く)を有し、且つ、遺伝子組換えによる乳酸生産強化系を備えている乳酸生産大腸菌と、この乳酸生産大腸菌を用いて、スクロースを含む植物由来原料から乳酸を生産する乳酸生産方法を提供する。
