Heterotrophic Bacteria Dominate Catalase Expression during Microcystis Blooms
DJ Smith, MA Berry, RM Cory… - Applied and …, 2022 - Am Soc Microbiol
In the oligotrophic oceans, key autotrophs depend on “helper” bacteria to reduce oxidative
stress from hydrogen peroxide (H2O2) in the extracellular environment. H2O2 is also a …
