标题 :Method for performing material synthesis, and method for absorbing co2 and producing succinic acid
发明人:TANABE MAIKO; SATO MIWA; WATANABE KOICHI; MOCHIZUKI ATSUSHI; OKADA TAKASHI

摘要:The present invention is a method for performing material synthesis by modifying one or more genes and culturing the modified organisms, thereby forming a metabolic pathway in which a CO2 discharge site that has not undergone gene modification turns into absorption. Specifically, succinic acid is synthesized by culturing an organism in which a gene that encodes a sodium-ion-dependent bicarbonate transporter and a gene that encodes a phosphoenolpyruvate carboxykinase are forcibly expressed, and the following reactions are initiated in a TCA cycle of the organism: (1) Succinyl-CoA + CO2 → α-ketoglutaric acid; (2) α-ketoglutaric acid + CO2 → D-isocitric acid
