Natural rubber latex microbial fresh keeping bacterium as well as preparation method and application thereof

The invention provides a natural rubber latex microbial fresh keeping bacterium, which is prepared from 80 to 150 parts of corn stalks, 3 to 4 parts of yeast powder, 5 to 10 parts of brown sugar, 40 to 60 parts of straws, 5 to 10 parts of lime powder and 0.01 to 0.02 part of 20-percent mannitol. The corn stalks and the straw stalks are used as major raw materials; a preservative capable of consuming albumen in the natural rubber latex through biological bacterium decomposition is prepared; a natural latex microbial fresh keeping bacterium with an ammonia water fresh keeping function is completely replaced; mannite is added into a fresh keeping microbial inoculum, so that a good anti-coagulation effect is achieved; after the addition, the stored natural rubber latex can have good flowability; the subsequent processing difficulty is lowered; in the use process, after 3 percent of the fresh keeping bacterium is added, the rubber latex can be stored for 270 days at normal temperature; the phenomena of qualitative
