Abstract
|
|
|
|
Bacillus licheniformis was an useful material for improvement of fecal microflora. The stability of Bacillus licheniformis in low pH (pH 2, 3, 4, 6, 7), artificial bile acid, high concentration of salt (0, 5, 10, 20, ), and ethanol (0, 4, 8, 16, ) was investigated in this study. The viability of Bacillus licheniformis was stable for pH 3, 4, 6, 7 Final viability of Bacillus licheniformis was confirmed below , in the bile acid. In high concentration of salt, Bacillus licheniformis showed optimal viability in of salt. The viability of Bacillus licheniformis was over in condition of ethanol concentration contrast with uncontained ethanol at for 4h. It was verified that Bacillus licheniformis was stable for pH 4, 6, 7, high concentration of salt and ethanol but was unstable in pH 2 and bile acid
