Receptor uptake arrays for vitamin B12, siderophores and glycans shape bacterial communities
, 2017 Molecular variants of vitamin B12, siderophores and glycans occur. To take up variant forms, bacteria may express an array of receptors. The gut microbe Bacteroides thetaiotaomicron has three different receptors to take up variants of vitamin B12 and 88 ...

The Porphinoids - Versatile Biological Catalyst Molecules
CHIMIA, 1987 The natural porphinoids, such as the iron complex heme, the magnesium complex chlorophyll a, the nickel complex coenzyme F430, and the (corrinoid) cobalt complex coenzyme B12 play central roles in all spheres of life, e.g.

Exploration of isoxanthohumol bioconversion from spent hops into 8-prenylnaringenin using resting cells of Eubacterium limosum [PDF]
, 2020 Hops is an almost unique source of the potent phytoestrogen 8-prenylnaringenin (8-PN). As hops contain only low levels of 8-PN, synthesis may be more attractive than extraction.

Influence of corrinoid antagonists on methanogen metabolism [PDF]
Journal of Bacteriology, 1981 Iodopropane inhibited cell growth and methane production when Methanobacterium thermoautotrophicum, Methanobacterium formicicum, and Methanosarcina barkeri were cultured on H2-CO2. Iodopropane (40 microM) inhibited methanogenesis (30%) and growth (80%) when M. barkeri was cultured mixotrophically on H2-CO2-methanol.

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]
, 2010 Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.
