Methanogens have a very limited substrate range, and their in situ activities are thus linked to 'intermediary ecosystem metabolism', i.e. complex trophic interactions with other microorganisms catalysing essential intermediary processes that ultimately drive methanogenesis. However, information on intermediary ecosystem metabolism and associated biota is fragmented and often conceptualized rather than resolved. The main objective of this review is to evaluate the concept of intermediary ecosystem metabolism in context with recent work aimed at resolving the complex trophic interactions of a methane-emitting peatland.
产甲烷菌的底物范围非常有限，因此它们的原位活性与“中间生态系统代谢”有关，即与其他微生物的复杂营养相互作用，催化最终驱动产甲烷作用的必要中间过程。然而，有关中间生态系统代谢和相关生物群的信息是零散的，并且通常是概念化的而不是解决的。本综述的主要目的是评估中间生态系统代谢的概念，同时考虑最近旨在解决排放甲烷的泥炭地复杂营养相互作用的工作。
