Novel Pathway for Corrinoid Compounds Production in Lactobacillus [PDF]
Vitamin B12 or cobalamin is an essential metabolite for humans, which makes it an interesting compound for many research groups that focus in different producer-strains synthesis pathways.

Genetic dissection of regulation by a repressing and novel activating corrinoid riboswitch enables engineering of synthetic riboswitches [PDF]
The ability to sense and respond to intracellular metabolite levels enables cells to adapt to environmental conditions. Many prokaryotes use riboswitches—structured RNA elements usually located in the 5′ untranslated region of mRNAs—to sense ...

Functional genomics of corrinoid starvation in the organohalide-respiring bacterium Dehalobacter restrictus strain PER-K23 [PDF]
De novo corrinoid biosynthesis represents one of the most complicated metabolic pathways in nature. Organohalide-respiring bacteria (OHRB) have developed different strategies to deal with their need of corrinoid, as it is an essential cofactor of ...

Substrate-driven microbial specialization and cooperative dechlorination of chlorinated pollutants in estuarine ecosystems [PDF]
Organohalide-respiring bacteria (OHRB) are globally distributed, yet their ecological roles in marine environments remain poorly understood, with few isolates characterized from these systems.

Complete genomes from a xenic Dolichospermum flosaquae FBCC-A233 culture reveal genome-inferred metabolic asymmetry with associated bacteria [PDF]
Cyanobacteria form phycosphere communities with associated bacteria, but genome-resolved resources are needed to formulate testable hypotheses about their metabolic interactions.

Identification and characterisation of an elusive bacterial enzyme system for chloromethane dehalogenation [PDF]
Chloromethane, a toxic gas primarily produced naturally, contributes to stratospheric ozone destruction. The anaerobic acetogen Acetobacterium dehalogenans can utilise chloromethane as a carbon and energy source, but the associated dehalogenase ...

Methanogenesis from tetramethylammonium and choline in Methanococcoides methylutens Q3c requires a nonpyrrolysine monomethylamine methyltransferase homolog [PDF]
Methanogenesis is a key biological process contributing to both global climate change and renewable energy via methane. Methylotrophic methanogenesis is an important, but often underappreciated, component of this process.

Laboratory evolution of E. coli with a natural vitamin B12 analog reveals roles for cobamide uptake and adenosylation in methionine synthase-dependent growth [PDF]
Bacteria encounter chemically similar nutrients in their environment, which impact their growth in distinct ways. Among such nutrients are cobamides, the structurally diverse family of cofactors related to vitamin B12 (cobalamin), which function as ...

Cobamide excretion allows Salmonella to transition from its anaerobic to aerobic lifestyle [PDF]
Cobamides (Cbas) are structurally complex biomolecules used by cells of all domains of life. However, de novo Cba biosynthesis occurs only in some bacteria and archaea.

Methanogenic activities signatures in broilers fed black soldier fly (Hermetia illucens) larvae-based diets [PDF]
Methanogenic archaea in the avian gut contribute to hydrogen turnover and thus play a role in fermentative efficiency and greenhouse gas emission. While black soldier fly larvae meal (BSFLM) has been explored as a replacement for fishmeal in broiler ...
