Abstract：
Microbial colonization and growth can have significant impacts on the built environment, resulting in a range of effects, from discolouration and staining to biodeterioration and decay. In some cases, formation of biofilms, crusts and patinas may confer bioprotection of the substrate. This Perspective aims to discuss how geomicrobial transformations in the natural environment—particularly those that involve rocks, minerals, metals and organic matter—may be applied to understand similar processes occurring on fabricated human structures. However, the built environment may offer further strictures as well as benefits for microbial activity, and these should be taken into account when considering analogy with natural processes, especially when linking observations of microbial biodiversity to the more obvious manifestations of microbial attack.

内容要点：

1、菌群的定殖与生长对建筑环境有显著影响，可能造成建筑表面褪色、染色，以及对建筑产生生物腐蚀；

2、在某些情况下，菌群形成的生物膜、外壳及锈蚀产物可能为建筑基质提供了保护作用；

3、在建筑环境下，菌群可能生长在表面、缝隙及岩石孔隙体系中，从大气、雨水、建筑表面的有机或无机残留物、其它细菌的代谢废物、植物及昆虫的降解产物等中获取营养物质；

4、紫外线照射、湿度、温度、营养物质等因素可能影响建筑环境中的菌群定殖。
