However, we could not statistically link the changes in the structure of the microbial communities over time with those in enzyme activity, which led us to assume that other factors, such as top-down regulation, are more important than microbial community structure in the determination of the enzyme secretions in the soil.
It also suggested the gut microbiota is inherited to a significant extent from the mothers, and that "inheritance" of the gut microbiota may be more important for microbial community structure and function than the actual genetic context of the host.
Microbial CH4 release was much more important than non-microbial CH4 release from fresh soils at different temperatures, when all land uses were considered together.
The N-mass balance [e.g., N2(g) and NH4+ and NO3−] suggests that abiotic reduction of NO3− dominated at the start of Fe0 treatment, whereas N2 production became more important once the microbial activity began.
A second, and perhaps more important, point is that microbial species do not generally occur as single strains or pure cultures.
"The fermenters producing hydrogen after multiple additions of acetate may be more important to the underlying microbial community than we once thought," said Philip E. Long, an LBNL geologist who manages research at the Rifle study site.
Soluble organic C is readily utilized by soil microbes, whereas particulate SOC is a more important nutrient source for microbial activity (Mahieu et al. 1999; Chen and Chiu 2003).
That's the conclusion from a genetic study of airborne bacteria in two U.S. cities that suggests the atmosphere may be a more important part of global microbial ecology than was assumed.
Our results suggest that although grapevine roots play a dominant role in the uptake of nutrients from a decomposing cover crop, AM hyphae may have a more important role in maintaining soil microbial communities associated with nutrient cycling.
Furthermore, it was reported that temperature was more important than trophic interaction in influencing microbial community (Gilbert et al. 2012), and the temperature dependence of microbial diversity is greatest at extreme nutrient level (Wang et al. 2016).
