Vital signs in the low energy microbial world: linking physiology to ecosystem function

Dr. Jacqueline Goordial
Bigelow Laboratory for Ocean Sciences, East Boothbay, Maine

Microorganisms are the most diverse and abundant lifeforms on Earth, but less than 1% have been cultured in the laboratory for study. Thus, our knowledge of the metabolic potential of the vast majority of microorganisms is based primarily on genomic and metagenomic sequencing. Compounding these unknowns is evidence that bacteria commonly exist in prolonged states of low metabolic activity or non-growth states in environmental settings. This gap in our knowledge necessitates uniting physiology and molecular microbiology to understand the roles that bacterial communities play in biogeochemical cycling and ecosystem function.
