Soil is composed of a mosaic of different rocks and minerals, usually considered as an inert substrata for microbial colonization. However, recent findings suggest that minerals, in soils and elsewhere, favour the development of specific microbial communities according to their mineralogy, nutritive content, and weatherability. Based upon recent studies, we highlight how bacterial communities are distributed on the surface of, and in close proximity to, minerals. We also consider the potential role of the mineral-associated bacterial communities in mineral weathering and nutrient cycling in soils, with a specific focus on nutrient-poor and acidic forest ecosystems. We propose to define this microbial habitat as the mineralosphere, where key drivers of the microbial communities are the physicochemical properties of the minerals.
土壤由不同的岩石和矿物质组成，通常被认为是微生物定殖的惰性基质。然而，最近的发现表明，矿物质在土壤中和其他地方根据其矿物学、营养含量和耐候性，有利于特定微生物群落的发展。基于最近的研究，我们强调了细菌群落如何分布在矿物质的表面和附近。我们还考虑了与矿物质相关的细菌群落在土壤风化和养分循环中的潜在作用，特别关注养分贫瘠和酸性的森林生态系统。我们建议将这个微生物栖息地定义为矿物圈，其中微生物群落的关键驱动因素是矿物质的物理化学性质。
