Screening of Lactic Acid Bacteriafor Producing a-Galactosidase from Chinese Traditional Fermented Foods

摘要

Twenty eight kinds of Chinese traditional fermented foods were collected to isolate Lactic Acid Bacteria (LAB) with α-galactosidase activity, which could eliminated those α-Galactooligosaccharides (α-GOS) regarded as anti-nutritional factors widely existed in agricultural byproducts animal feeds. Three strains, including Lactobacillus salivarius XA1R (JX125455) and XH4B (JX125456) and Pediococcus acidilactici XS1B (JQ927329), could ferment well in soybean meal and other agricultural byproducts and had a-galactosidase activity S.81-S.92 U/mL in soybean meal culture.
