不同选择性培养基对乳酸菌生长的影响

The effect of the different selected media on the growth of lactics

乳酸菌在不同种类、不同类型选择性培养基上生长培养后,比较活菌菌落数、菌落大小及溶钙圈大小。结果显示:添加胡萝卜汁的乳酸菌分离半固体培养基最适合乳酸菌的培养,活菌数最多,菌落最大。

The optimal media for the growth of lactics was choosen by detecting the number, size of colony and the size of calcium-dissolving zone when the bacteria grew in different solid and semi-solid media. The results showed that the growth of the lactics was best, the number of living bacteria was the largest and the calcium-dissolving zone was the biggest when the bacteria grew in the lactics detaching solid media which adding carrot juice.
