Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions
Advanced Science, Volume 12, Issue 46, December 11, 2025.Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.

Anaerobic Limonene Metabolism in a Methanogenic Enrichment Involves a Glycine Radical Enzyme
Environmental Microbiology, Volume 27, Issue 11, November 2025.A methanogenic enrichment culture on the natural monoterpene limonene is characterised by a novel glycine radical enzyme for anaerobic hydrocarbon activation, the presence of a microbial loop for necromass utilisation and the presence of a predator of Bacteria and Archaea. ABSTRACT Limonene is a natural monoterpene omnipresent in human environments. It

Expansion of cagA Copy Number in Helicobacter pylori During Co‐Infection in a Mouse Model
Helicobacter, Volume 30, Issue 6, November/December 2025.ABSTRACT Introduction The virulence factor CagA is critical in mediating inflammation, and Helicobacter pylori PMSS1 dynamically modulates cagA copy number in response to host immune pressure. Co‐infection with Salmonella enterica serotype Typhimurium has been shown to heighten systemic inflammation and reduce H.

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.

Journal of the Science of Food and Agriculture, Volume 105, Issue 10, Page 5239-5245, 15 August 2025.Abstract BACKGROUND Fermenting soy milk with lactic acid bacteria is challenging. Generally, carbohydrates are added to enhance the acid production in soy milk. However, the yoghurt starter Lactobacillus delbrueckii subsp. bulgaricus did not succeed in fermenting soy milk supplemented with carbohydrates.

Microbial Biotechnology, Volume 18, Issue 6, June 2025.Molecular and functional experiments highlight the relevance of species‐specific polymorphisms in a B12 riboswitch of the Mycobacterium genus. This information provided proof‐of‐concept to engineer a whole‐cell biosensor capable of detecting vitamin B12. ABSTRACT Vitamin B12 metabolism differs among members of the Mycobacterium genus.
