TL;DR: To evaluate the role of pH, total organic carbon, and other geochemical parameters in shaping bacterial communities within a single karst system in central China, samples were collected from the thin surface soils overlying Heshang Cave, cave sediments, and weathered cave passage rocks from the entrance, twilight, and dark zones, as well as from epikarstic drip waters inside the cave.

TL;DR: In this article, the ability of methanogen Methanosarcina barkeri to reduce structural Fe(III) in iron-rich smectite (nontronite NAu-2) and the relationship between iron reduction and methanogenesis were investigated.

TL;DR: It is suggested that Bathyarchaeota may play an important ecological role within archaeal communities via a potential symbiotic association with Methanomicrobia, and 9 indicator groups are identified among the 6 habitats with the most in the estuary sediments.

TL;DR: In this paper, the authors demonstrate through laboratory carbonation experiments that highly negative-charged clay minerals such as illite and montmorillonite can aid the precipitation of abiotic proto-dolomite under ambient conditions, whereas nearly neutral charged kaolinite exerts negligible influence on such process.

TL;DR: The finding that more carboxyl groups were presented on the cell surface under high salinity conditions to resist the high osmotic pressure, which may result in the subsequent promotion of dolomite formation suggests a link between variations in the hydro-chemical conditions and the formation of dlomite via microbial metabolic activity.
