Growth of Lactobacillus acidophilus Group Strains Isolated from Human Intestines in Skim Milk and Cheese Whey

Abstract

　Lactobacillus acidophilus group lactic acid bacteria isolated from human feces in our laboratory and identified by DNA-DNA hybridization were evaluated by the growth in skim milk and cheese whey. Growth of LA67 (L. acidophilus) was predominantly well in skim milk broth but growth of other L. gasseri strains in cheese whey broth were also appreciable followed by LA67. These strains were expected to use as probiotics for making fermented milk products.
