Scientists from Berkeley Lab and PNNL have found that genes and early environment play big roles in shaping the gut microbiome. The microbes retained a clear “signature” formed where the mice were first raised, and the characteristics carried over to the next generation. The findings could potentially be used to develop designer diets optimized to an individual’s microbiome.
The initiative will advance the understanding of microbiome behavior and enable the protection of healthy microbiomes, which are communities of microorganisms that live on and in people, plants, soil, oceans, and the atmosphere. Microbiomes maintain the healthy function of diverse ecosystems, and they influence human health, climate change, and food security.
It’s no secret that extremophiles, or microbes that live in places like polar glaciers and toxic waste pools, may hold treasures worth billions. Now basic biology research has led to the formation of CinderBio, a startup co-founded by Berkeley Lab scientists Steve Yannone and Jill Fuss that produces heat- and acid-stable enzymes.
Scientists Call for National Effort to Understand and Harness Earth’s Microbes for Health, Energy, Agriculture, and Environment
Biocrust’s microbes lie dormant for long periods until precipitation (such as a sudden downpour) awakens them. Understanding more about the interactions between the microbial communities—also called “microbiomes”—in the biocrusts and their adaptations to their harsh environments could provide important clues to help shed light on the roles of soil microbes in the global carbon cycle.
Scientists discovered that coffee berry borers worldwide share 14 bacterial species in their digestive tracts that degrade and detoxify caffeine. They also found the most prevalent of these bacteria has a gene that helps break down caffeine. Their research sheds light on the ecology of the destructive bug and could lead to new ways to fight it.
