| Summary: | 碩士 === 朝陽科技大學 === 生化科技研究所碩士班 === 98 === This research studied the effect of commonly used dietary Chinese herbs on the growth of one of the important lactic acid bacteria, Enterococcus faecium. Water extract of Astragali Radix, Ginseng Radix, Sophorae Radix, Adenophorae Radix, Salivae Miltiorrhizae Radix, Codonopsitis Radix, Scrophulariae Radix and Panacis Quinquefolii Radix, and eighteen other dietary Chinese herbs were added to the liquid culture of E. faecium at various concentration, and cell concentrations were quantified in CFU/mL. Experimental results showed that in 8% w/v goat milk culture medium, the addition of Panacis Quinquefolii Radix, Codonopsitis Radix and Magnolia officinalis extracts exhibited significant growth promotion of up to 1.8 times (3.6×109CFU/mL). Among other tested Chinese herbs, Astragali Radix, Agastache rugosus, Zizyphus jujube, Glycyrrhiza uralensis Fisch and Atractylodes lancea exhibited inhibitory effect on the growth of E. faecium.
