DOI: 10.1021/acsomega.2c02830
Abstract: Microorganisms are the core drivers of coal biogeochemistry and are closely related to the formation of coalbed methane. However, it remains poorly understood about the network relationship and stability of microbial communities in coals with… read more here.
