| Abstract: | This paper studies the method of the rapid isolation and purification of thermophilic streptococcus lactic from fermented milk.Coating partition method is used to separate thermophilic streptococcus lactic on the bromcresol purple indicator of cow’s milk nutrient agar plate and the effect is quite well.The result showed that this method can attain its well separation.The bacterial strain isolated is identified as pure thermophilic streptococcus lactic through microscopic examination and fermentation test,so this method can be used for the detection of antibiotics in milk. |
