Screening of Lactobacillus plantarum with High Level Folate and Their Application Researches

Abstract:

The human being can not synthesize folate by themselves，mainly from food. Lactobacillus plantarum（Lb. plantarum） can produce folate，and recognized as an intestinal probiotics. Studying higher-yield folate Lb. Plantarum，which isolated from Yunnan traditional fermented food，totaled 34 strains，combining high performance liquid chromatography（HPLC）. Through comparing，the 34 Lb. Plantarum also have the ability to synthesize folate，and the three highest yields are Lb. plantarum SP8-7，JH-M1-6-30 and YML4-3，1.492，1.360 μg/mL and 1.312 μg/mL respectively. In the aspect of applied research，Lb. plantarum JH-M1-6-30 and Lb. plantarum YML4-3 can be used in producing yoghurt which containing higher-yield folate，and Lb. plantarum SP8-7 can be used in producing acid douchi which containing higher-yield folate.
