Carbon Storage and the Life Cycle of Microbes

Research into the life and death of microbes in response to climate change and its effects on the carbon they store will soon begin.

LLNL team wins $15 million to study how microbes affect carbon storage

Do dead microbes control the future of Earth’s climate? A team of researchers led by Lawrence Livermore National Laboratory (LLNL) suspects they might. Using new tools, the team can see which soil organisms are thriving and which are dying in California’s changing climate and what happens to carbon in their cell biomass when they do.

In wild soil, predatory bacteria grow faster than their prey

 E-Mail Predatory bacteria bacteria that eat other bacteria grow faster and consume more resources than non-predators in the same soil, according to a new study out this week from Northern Arizona University. These active predators, which use wolfpack-like behavior, enzymes, and cytoskeletal fangs to hunt and feast on other bacteria, wield important power in determining where soil nutrients go. The results of the study, published in the journal mBio this week, show predation is an important dynamic in the wild microbial realm, and suggest that these predators play an outsized role in how elements are stored in or released from soil. Like every other life form on earth, bacteria belong to intricate food webs in which organisms are connected to one another by whom they consume and how. In macro webs, ecologists have long understood that when resources like grass and shrubs are added to lower levels of the web, predators at the top, such as wolves, often benefit. The research te
