The skin microbiome is a key player in human health, with diverse functions ranging from
defense against pathogens to education of the immune system. While recent studies have …

BACKGROUND Nearly every plant, animal, and environment on earth is host to a diverse
community of microorganisms that influence each other and their environment …

Vitamin B12 (the cyanated form of cobalamin cofactors) is best known for its essential role in
human health. In addition to its function in human metabolism, cobalamin also plays …

The vitamin B12 family of cofactors known as cobamides are essential for a variety of
microbial metabolisms. We used comparative genomics of 11,000 bacterial species to …

The human skin microbiome could provide another example, after the gut, of the strong
positive or negative impact that human colonizing bacteria can have on health. Deciphering …

The microbial mechanisms and key metabolites that shape the composition of the human
gut microbiota are largely unknown, impeding efforts to manipulate dysbiotic microbial …

ABSTRACT Cobalamin (vitamin B12; VB12) is an indispensable nutrient for all living entities
in the Earth's biosphere and plays a vital role in both natural and host environments …

B vitamins are intricately involved in various physiological processes vital for health. Their
significance is complicated by the heterogeneous landscape of B vitamin distribution in diets …

Microbial communities thrive in a number of environments. Exploration of their microbiomes–
their global genome–may reveal metabolic features that contribute to the development and …
