Vitamin B consists of a group of water-soluble micronutrients that are mainly derived from
the daily diet. They serve as cofactors, mediating multiple metabolic pathways in humans. As …

Vitamin B12 is assimilated and transported by complex mechanisms that involve three
transport proteins, intrinsic factor (IF), haptocorrin (HC) and transcobalamin (TC) and their …

Mutualism is commonly observed in nature but not often reported for bacterial communities.
Although abiotic stress is thought to promote microbial mutualism, there is a paucity of …

Despite accumulating data on microbial biogeographic patterns in terrestrial and aquatic
environments, we still lack a comprehensive understanding of how these patterns establish …

The transfer of nutrients between cells, or cross-feeding, is a ubiquitous feature of microbial
communities with emergent properties that influence our health and orchestrate global …

Vitamins have well-established roles in bacterial metabolism. Menaquinones (MKn, n=
prenyl units in sidechain) are bacterially produced forms of vitamin K produced by the gut …

Inoculation can effectively improve the recycling level of organic waste in composting
process. However, the role of inocula in the humification process has been rarely studied …

Vitamin B12 (cobalamin, herein B12) is an essential cofactor involved in amino acid
synthesis and carbon resupply to the TCA cycle for most prokaryotes, eukaryotic …

Cobamides are required by most organisms but are only produced by specific prokaryotic
taxa. These commonly shared cofactors play significant roles in shaping the microbial …

Previous studies often attribute microbial reductive dechlorination to organohalide-respiring
bacteria (OHRB) or cometabolic dechlorination bacteria (CORB). Even though …
