Unveiling the significance of prokaryotic composition from ferromanganese crusts regarding the interlink between cobalt and vitamin B12 in deep-sea ecosystems

Frontiers in Microbiology
The intricate relationship between prokaryotic vitamin B12 (cobalamin) producers and metazoans in deep-sea ecosystems, particularly within ferromanganese crusts and polymetallic nodules, is critical for understanding oceanic biogeochemical cycling of ...

Cobalamin inactivation induces formyltetrahydrofolate synthetase

, 1990
Loss of cobalamin function produces profound changes in the metabolism of formate. There is impaired synthesis of formyltetrahydropteroylglutamate synthetase (CHO-H4,PteGlu), accumulation of endogenous formate and impaired utilization of [14C]formate ...

Synergistic Benefits of Butyric Acid and Resistant Potato Starch on Growth and Gut Health in Weaned Pigs

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Newly‐weaned piglets face challenges such as reduced feed intake, impaired gut function, and susceptibility to post‐weaning diarrhoea, increasing the need for dietary strategies that support gut health and growth. This study investigated the effects of dietary supplementation with butyric acid (BA), resistant potato starch (PS), and their ...

Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, EarlyView.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

A cobalt concentration sensitive Btu-like system facilitates cobalamin uptake in Anabaena sp. PCC 7120

Microbial Cell
Metal homeostasis is central to all forms of life, as metals are es-sential micronutrients with toxic effects at elevated levels. Macromolecular machines facilitate metal uptake into the cells and their intracellular level is regulated by multiple means,

Cobalamin, the stomach, and aging [PDF]

The American Journal of Clinical Nutrition, 1997
Low cobalamin concentrations are common in the elderly. Although only a minority of such persons display clinically obvious symptoms or signs, metabolic data clearly show cellular deficiency of cobalamin in most cases. The evidence suggests that this is not a normal physiologic expression of the aging process. Rather, the elderly seem at increased risk
