    Abstract

    Metabolites from Lactobacillus acidophilus were analysed. The results showed that Lactobacillus acidophilus Ind-1 and Lactobacillus acidophilus Lakcid produced respectively 12.73 g and 13.33 g lactic acid l¿1 after incubating in skim milk at 37 °C for 36 h; and 2.229 unit and 1.808 unit ß-galactosidase l¿1 in an MRS medium. The proteolytic activity of Lactobacillus acidophilus was high and the content of 17 free amino acids in the fermented milk of Lactobacillus acidophilus Ind-1 and Lactobacillus acidophilus Lakcid was 394.4 mg l¿1 and 563.2 mg l¿1, respectively. Meantime, Lactobacillus acidophilus reduced cholesterol level in an MRS medium supplemented with cholesterol. Furthermore, Lactobacillus acidophilus Ind-1 and Lactobacillus acidophilus Lakcid showed antimicrobial activity against Bacillus anthracis and Escherichia coli
