研究表明，一些海绵微生物是可以通过传统分离手段得到的，来自同一或者不同海绵的微生物均具有丰富的基因多态性。

It was proved that we can obtain sponge-associated microorganisms by traditional isolation method and there is genetic diversity among strains from the same or different sponges.

由微生物种群的多态性必然引起微生物种群作用特征的多态性、发酵代谢产物的多态性，必然也引起产酒质量的多态性。

Then microbial polymorphism would undoubtedly result in the polymorphism of microbial population functions, the polymorphism of metabolites, and the polymorphism of liquor quality.
