Vitamin B12: prevention of human beings from lethal diseases and its food application

Journal of the Science of Food and Agriculture, Volume 105, Issue 1, Page 10-18, 15 January 2025.
Abstract Vitamin B12, a water‐soluble essential micronutrient, plays a pivotal role in numerous physiological processes in the human body. This review meticulously examines the structural complexity and the diverse mechanisms through which vitamin B12 exerts its preventive effects against a spectrum of health conditions, including pernicious anaemia ...

Coexistence of two distinct Sulfurospirillum populations respiring tetrachloroethene - genomic and kinetic considerations [PDF]

, 2018
Two anaerobic bacterial consortia, each harboring a distinct Sulfurospirillum population, were derived from a 10 year old consortium, SL2, previously characterized for the stepwise dechlorination of tetrachloroethene (PCE) to cis-dichloroethene (cis-DCE)

Porphyrin and corrinoid mutants of Bacillus subtilis [PDF]

Journal of Bacteriology, 1977
Porphyrin auxotrophs of Bacillus subtilis can be divided into two groups. Strains belonging to the first group (hemA, hemB, or hemC) are not able to synthesize or metabolize porphobilinogen. These strains require cysteine, cystine, and methionine, respectively.

Ultrafine Metallic Particles as Inducers of Digestive Processes in Rumen: Dry Matter Digestibility of Feed and Enzymatic Activity

Scientifica, Volume 2025, Issue 1, 2025.
The ban on the use of antibiotics in animal husbandry encourages an active search for highly effective alternatives with additional properties, one of which is ultrafine particles (UFP) of metallic nature. The objective of the presented work was to conduct a comprehensive analysis of newly synthesized UFP Co3O4 and Mn2O3, including determination of ...

Isolation and characterization of a novel methanogen Methanosarcina hadiensis sp. nov. from subsurface Boom Clay pore water

Environmental Microbiology, Volume 26, Issue 12, December 2024.
We isolated a novel methanogenic archaeon, Methanosarcina hadiensis sp. nov. (TD41E1‐1), from Boom Clay pore water at a depth of 225 m. It exhibits unique characteristics compared to previously characterized Methanosarcina species, such as the inability to perform acetoclastic methanogenesis and the presence of extensive surface appendages.
