| Summary |
In this experiment, the bacillus stearothermopilus was used as standard sensitive bacteria and the bacteria were quantitated with spectrophometer to estimate inhibitory material in milk production.
Totally 732 samples of fresh milk were tested and compared with the data obtained from the method of China National Standard (CNS). The result shows (!) quantitating the bacteria with spectrophotometer can simplify the procedure of the estimation; (2) the bacillus stearotherphilus was more sensitive to the inhibotory material than the bacteria of CNS.
