We observed that Lactobacillus reuteri JCM1112 produces B(12) and folate. However, the folate/B(12) mass ratio found was far below that desired for human consumption ( approximately 170:1). We used metabolic engineering applying genetic and physiological approaches to improve this ratio and developed a generic and natural process that significantly increases folate production.
我们观察到罗伊氏乳杆菌JCM1112能产生维生素B12和叶酸。然而,所发现的叶酸与维生素B12的质量比远低于人类食用所需的比例(约为170:1)。我们采用代谢工程,运用遗传和生理学方法来提高这一比例,并开发出一种通用的天然方法,可显著提高叶酸产量。
