The studies open up new opportunities to uncover microbial genomes from other environments, revealing how microbes alter global carbon and nitrogen cycles,
how microbial metabolism evolved, and how so many different kinds of microbes can coexist, says biological oceanographer Paul Falkowski of Rutgers University in New Brunswick, New Jersey.
To find out why, computational biologists came up with a computer model to predict
how microbial metabolism and cellular composition change as cell size varies, using details about how much space a bacterium needs for its components — DNA, proteins, and the molecular factories called ribosomes — to function.

Still, he adds, «there's a lot more basic biology that will need to be worked out to fully appreciate the mechanisms that cause sweeteners to alter gut
microbial community composition and function, and
how in turn this shapes host
metabolism.»
With our new found understanding of
how Bacteria and Archaea impact global biogeochemical cycling, the differential role of divergent
microbial metabolisms and lineages in food webs must be addressed.
If it can be shown that these bacteria survive and reproduce in such extreme conditions, Christner's work may allow climate researchers to estimate
how much carbon dioxide measured in the ice might have come from
microbial metabolism rather than the atmosphere.
