Title (EN) METHOD FOR CULTURING LACTIC ACID BACTERIA
(FR) PROCÉDÉ DE CULTURE DE BACTÉRIES LACTIQUES
(JA) 乳酸菌の培養方法
Abstract:
(EN) Provided is a method for culturing lactic acid bacteria that inhibits lactic acid production in a variety of lactic acid bacteria and enables high density culture. Lactic acid bacteria are cultured by fed-batch culture. When lactic acid bacteria are cultured by fed-batch culture, lactic acid production is inhibited in comparison to culture by batch culture, and the inhibition of lactic acid bacterial growth caused by high lactic acid concentrations can then be reduced. The culture of lactic acid bacteria can thus be carried out at a higher density than in the case of the batch culture of lactic acid bacteria.
(FR) La présente invention concerne un procédé de culture de bactéries lactiques qui inhibe la production d’acide lactique dans une diversité de bactéries lactiques et permet une culture à haute densité. Les bactéries lactiques sont cultivées par culture en cuvée alimentée. Lorsque les bactéries lactiques sont cultivées par culture en cuvée alimentée, la production d’acide lactique est inhibée comparativement à la culture par culture en cuvée, et l’inhibition de la croissance des bactéries lactiques provoquée par des concentrations élevées en acide lactique peut alors être réduite. La culture des bactéries lactiques peut ainsi être effectuée à une densité supérieure à celle dans le cas de la culture en cuvée de bactéries lactiques.
(JA) 種々の乳酸菌の乳酸生成を抑制し、高密度培養を可能とする乳酸菌の培養方法を提供する。流加培養により乳酸菌を培養する。流加培養により乳酸菌を培養すると、回分培養で培養した場合と比べて、乳酸の生成が抑制され、乳酸濃度が高くなることに起因する乳酸菌の増殖阻害を低減できる。したがって、回分培養で乳酸菌を培養した場合と比べて、高密度で乳酸菌を培養することが可能となる。
