产维生素B_6乳酸菌的筛选及其鉴定

Screening and identification of Lactobacillus Strains for Vitamin B_6 production

以源自内蒙古呼和浩特市婴儿粪便选出的10株乳酸杆菌为试验材料,通过微生物分析方法,筛选乳酸菌合成维生素B6能力较强的菌株并对其进行初步鉴定。结果表明,有4株菌株B25、B72、B76和N59-1合成维生素B6的能力较高,其中菌株N59-1合成维生素B6的量可高达32.62 g/100 L,菌株N59-1经鉴定为植物乳杆菌。

10 LactobaciUus strains isolated from infant faeces in Huhhot were assayed for Production of Vitamin B6 by Microbiological methods in the paper. Results showed that 4 strains, B25 ,B72、B76 and N59-1 had higher vitamin B6 Production activity. The N59-1 had highest capability of vitamin B6 Production than others, the yield was 32.62 mg/100 mL. N59-1 was further identified to Lactobacillus plantarum as potential probiotics.
