Microbial biofilms are multicellular communities of sessile microorganisms encased by the hydrated polymeric matrix. They have significant influences on both aquatic/terrestrial ecosystem and anthropogenic activities. Taking advantage of the governing features of selective stress (Tan and Ng in Water Res 42:1122-1132, 2008; Wei in Water Res 45:863-871, 2011; Dereli in Water Res 59C:11-22, 2014), the evenness of microbial communities in a membrane-centered mesocosm was successfully manipulated. By measuring the biofilm growing rates under different evenness levels of communities, an evenly distributed community favors the formation of biofilms was observed. This finding is not only a new evidence linking biofilm diversity to its functionality but also a clear suggestion on controlling a biofilm-based process via a simple and smart way.
微生物生物膜是由水合多聚物基质包裹的、静止微生物的多细胞群落。它们对水生/陆地生态系统和人为活动都有重要影响。利用选择性压力的控制特性（Tan 和 Ng 在 Water Res 42:1122-1132, 2008; Wei 在 Water Res 45:863-871, 2011; Dereli 在 Water Res 59C:11-22, 2014），成功地控制了膜中心中型生境中微生物群落的均匀性。通过测量不同均匀度水平下的生物膜生长速率，观察到均匀分布的群落有利于生物膜的形成。这一发现不仅为生物膜多样性与其功能之间的联系提供了新的证据，而且还为通过简单而巧妙的方式控制基于生物膜的过程提供了明确的建议。
