ProteomicsAtmospheric hydrogen oxidation extends to the domain archaea
Diverse aerobic bacteria use atmospheric hydrogen (H2) and carbon monoxide (CO) as energy sources to support growth and survival. Though recently discovered, trace gas oxidation is now recognised as a globally significant process that serves as the main sink in the biogeochemical H2 cycle and sustai...

ProteomicsMycobacteria tolerate carbon monoxide by remodelling their respiratory chain
Carbon monoxide (CO) is a gas infamous for its acute toxicity. The toxicity of CO predominately stems from its tendency to form carbonyl complexes with transition metals, thus inhibiting the heme-prosthetic groups of proteins, including the terminal oxidases of the respiratory chain. While CO has be...

MetabolomicsAn obligate aerobe adapts to hypoxia by hybridising fermentation with carbon storage
In soil ecosystems, obligately aerobic bacteria survive oxygen deprivation (hypoxia) by entering non-replicative persistent states. Little is known about how these bacteria rewire their metabolism to stay viable during persistence. The model obligate aerobe Mycobacterium smegmatis maintains redox ho...

ProteomicsAn obligate aerobe adapts to hypoxia by hybridising fermentation with carbon storage
In soil ecosystems, obligately aerobic bacteria survive oxygen deprivation (hypoxia) by entering non-replicative persistent states. Little is known about how these bacteria rewire their metabolism to stay viable in these states. One obligate aerobe, Mycobacterium smegmatis, maintains redox homeostas...

MetabolomicsProtozoal populations drive system-wide variation in the rumen microbiome

While rapid progress has been made to characterize the bacterial and archaeal populations of the rumen microbiome, insight into how they interact with keystone protozoal species remains elusive. Here, we reveal two distinct rumen community types (RCT-A and RCT-B) that are not strongly associated ...
