Despite the valid assumption that soil microorganisms play pivotal roles in regulating soil
organic matter (SOM) decomposition, there is limited evidence on whether there is a direct
link between microbial functional gene abundance and its function in soil carbon (C)
dynamics. This knowledge gap has precluded the development of frameworks to directly
include specific microbial functional gene abundance in Earth system models (ESMs),
leading to some inevitable uncertainties (Sulman et al., 2018). For example, extracellular …

Daqu is the starter of Baijiu, it provides the microbes and enzymes necessary for
fermentation. Studies have already established carbohydrate metabolism as the primary
functional module in Daqu fermentation. The present study investigated the changes in
microbial functions and the relationship between carbohydrate metabolism-related
functional genes and extracellular enzyme activity during the Daqu fermentation. Amplicon
sequencing identified 38 bacterial and 10 fungal phyla in Daqu samples, while shotgun …
