Cross-regulation of amino acid synthesis and anaerobic electron transfer by MetR-mediated methionine signaling [PDF]

Journal of Bacteriology
Microorganisms living in nutrient- and energy-limited environments must finely coordinate anabolic and catabolic pathways. However, the molecular mechanisms underlying this balance remain poorly understood.

Differential Organic Carbon Mineralization Responses to Soil Moisture in Three Different Soil Orders Under Mixed Forested System

Frontiers in Environmental Science, 2021
Soil microbial respiration is one of the largest sources of carbon (C) emissions to the atmosphere in terrestrial ecosystems, which is strongly dependent on multiple environmental variables including soil moisture.

Extracellular electron transfer increases fermentation in lactic acid bacteria via a hybrid metabolism

eLife, 2022
Energy conservation in microorganisms is classically categorized into respiration and fermentation; however, recent work shows some species can use mixed or alternative bioenergetic strategies.
