Siderophore-Mediated Interactions Determine the Disease Suppressiveness of Microbial Consortia.

abstract：:Methylobacter species, members of the Methylococcales, have recently emerged as some of the globally widespread, cosmopolitan species that play a key role in the environmental consumption of methane across gradients of dioxygen tensions. In this work, we approached the question of how Methylobacter copes with hypoxia,...
