Most organisms use oxygen to convert food into energy. However, in environments with little or no oxygen, life had found other ways to produce energy, using a process called fermentation. To better understand the range of bacteria and archaea that rely on this form of metabolism, researchers at UC Davis and UC Santa Barbara recently compiled a list of with more than 8,300 organisms from multiple sources, including the DOE Joint Genome Institute (JGI) and the DOE Systems Biology Knowledgebase (KBase). The researchers also built an interactive browser that allows other researchers to study the genomes and predict the metabolic abilities of microbes that are likely to thrive in environments with little or no oxygen.
UC Davis, Berkeley Lab Team up to Advance Green Agriculture
Three University of California, Davis, Faculty Fellows have been awarded $25,000 each to spearhead cross-campus research projects with Berkeley Lab scientists in the field of agricultural decarbonization. With agricultural activities contributing over 10% of the United States’ total greenhouse gas emissions, the sector is a prime target for lowering emissions and addressing the climate crisis. The teams will explore innovative methods to remove and store excess carbon dioxide from the atmosphere—a practice known as carbon sequestration—and minimize energy consumption in crop production.
EcoFAB: A Tool for Combating Climate Change and Training the Next Generation
Fabricated ecosystems—EcoFABs—are plastic, takeout box–sized growth chambers developed at Berkeley Lab to be a standardized and reproducible platform for conducting experiments on model plants and the microbes that live around their roots. A greater understanding of how plants and microbes work together to store vast amounts of atmospheric carbon in the soil will help in the design of better bioenergy crops for the fight against climate change.
Improving Climate Predictions by Unlocking the Secrets of Soil Microbes
A Berkeley Lab–led team of scientists has developed a new model that incorporates genetic information from microbes, enabling them to ascertain how soil microbes store carbon supplied by plant roots. The model could inform agricultural strategies to preserve carbon in the soil, supporting both plant growth and climate change mitigation.
Rising Sea Levels Could Mean Higher Wetlands Methane Emissions
Area researchers led a team that examined the microbial, chemical, and geological features of 11 wetland zones in the Bay Area. Their findings indicate that the factors governing how much greenhouse gas is stored or emitted in natural landscapes are more complex and difficult to predict than previously thought.
