Based on the experiment of biofilm A/O process, the feasibility of brief-nitrification in attached microorganism system is studied.

基于菌膜厌氧好氧工艺法流程试验，对附着微生物简短硝化的可行性进行了研究。

AIM: To study the architecture of human plaque biofilm.

目的：研究菌斑生物膜的结构。

But nonpathogenic Saccharomyces cerevisiae couldn't produce biofilm.

非致病的酿酒酵母不能形成生物膜。

And the biofilm formation was performed in 96 well polystyrene plate.

用96孔聚苯乙烯板进行生物膜形成试验。

Normally, viruses have a hard time penetrating the dense layers of a biofilm.

通常病毒很难穿透稠密的生物膜。
