Community Profile and Drivers of Predatory Myxobacteria under Different Compost Manures

Myxobacteria are unique predatory microorganisms with a distinctive social lifestyle. These taxa play key roles in the microbial food webs in different ecosystems and regulate the community structures of soil microbial communities. Compared with conditions under conventional management, myxobacteria...

Community Profile and Drivers of Predatory Myxobacteria under Different Compost Manures
description Myxobacteria are unique predatory microorganisms with a distinctive social lifestyle. These taxa play key roles in the microbial food webs in different ecosystems and regulate the community structures of soil microbial communities.
