Zusammenfassung:	To provide culture method of lactic acid bacteria that suppress the production of lactic acid in various lactic acid bacteria to enable high-density culture.SOLUTION: As a sugar source, lactic acid bacteria are cultured using a medium in which sugars other than glucose are blended. When culturing using a sugar other than glucose as a sugar source, the production of lactic acid is suppressed and the growth inhibition of lactic acid bacteria caused by an increase in lactic acid concentration can be reduced, compared with when culturing in a medium using glucose as a sugar source. Therefore, culturing lactic acid bacteria at a higher density as compared with when culturing in a medium containing glucose as a sugar source becomes possible.SELECTED DRAWING: Figure 1 【課題】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。【解決手段】糖源として、グルコース以外の糖を配合した培地を用いて乳酸菌を培養する。糖源としてグルコース以外の糖を用いて培養を行うと、糖源としてグルコースを用いた培地で培養した場合と比べて、乳酸の生産が抑制され、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、糖源としてグルコースを含有する培地で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。【選択図】図１
