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.

Geomicrobiology of the built environment

内容要点：

1、30年前，大部分微生物被人类敬而远之，但随着“卫生假说” 的提出，很多证据表明 相对于一尘不染的环境中长大的孩子，接触更丰富微生物的宝宝更少发生过敏、哮喘等疾病；

2、包括一项纳入27.5万儿童在内的研究，证明家庭里的狗、猫等宠物，与孩子的过敏或哮喘发生率降低有关；

3、宠物可能通过毛发、爪子等将家庭外的微生物带回家，也可能成为家庭成员间微生物交流的媒介；

请注意，本研究所指猫或狗等宠物并非流浪猫狗，是正常途径获取的经过接种疫苗的家养宠物猫狗（非烈性大型犬、猫）。
