Developing a metabolic framework of the gut microbial ecosystem
Hundreds of diverse microbes stably colonize the human gastrointestinal tract and makeup the gut microbiome. While only certain types of microbes are adapted for life in the gut, the presence and abundance of particular microbes within the microbiome varies greatly across the population. Read more

Mechanisms and applications of microbial bioelectrochemistry
Some anaerobic microbes use a process called extracellular electron transfer to route their respiratory electron transport chains to the exterior of the cell. Once outside the cell electrons can be captured with an electrode, facilitating the conversion of the energy in organic matter into electricity. Read more
