[Differential Responses of Indigenous Microorganisms to Salinity Changes in Lake Sediments： A Case Study of the Baiyangdian Lake and Qinghai Lake].

）. Manipulating the salinity of the original sample resulted in the inhibition of the DAMO process in the lake sediment, leading to lower DAMO microbe abundance, reduced methane oxidation, and increased nitrous oxide production. These findings underscore the marked impact of lake salinity on indigenous microorganisms in lake sediments, with implications for their responses to changes in the salinity environment and subsequent effects on the DAMO process in lakes. This provides insights for predicting lake greenhouse gas emissions in the context of climate warming.
