Lactobacillus

　In the former articles, I told everybody the microbes has different shapes and sometimes we could distinguished them by their names. So, In this articles, I introduce the microbe calls Lactobacillus. In its name, we can see that has the words, bacillus, that is , the shape of Lactobacillus may be rod shape！

　They are a major part of the lactic acid bacteria group, named as such because most of its members convert lactose and other sugars to lactic acid. In humans they are present in the vagina and the gastrointestinal tract, where they are symbiotic and make up a small portion of the gut flora.The production of lactic acid makes its environment acidic which inhibits the growth of some harmful bacteria. For us, Lactobacillus is a good microbes, sometimes we could get it from some drugs.

In food industry, Lactobacillus always be the fermented bacteria in yougrt, or add it in some milk. I have had did a experiment that add the Lactobacillus spp. in milk, and examined the quantity of the bacteria in the feces. If the quantity was large, that means the bacteia could grew in the gastrointestinal tract via add it in milk.

anyway, for human, Lactobacillus is one of the probiotic bacteria.
