Burning question: Rethinking organohalide degradation strategy for bioremediation applications

Microbial Biotechnology, Volume 17, Issue 8, August 2024.
This review specifically focuses on the novel solution of organohalide bioremediation, proposing redox‐potential‐mediated hybrid bioprocesses tailored to the complexities of organohalide pollution. Abstract Organohalides are widespread pollutants that pose significant environmental hazards due to their high degree of halogenation and elevated redox ...

Acheta domesticus (house cricket) as human foods ‐ An approval of the European Commission ‐ A systematic review

Food Frontiers, Volume 5, Issue 2, Page 435-473, March 2024.
Acheta domesticus (house cricket) is recently approved by Commission Implementing Regulation (EU) 2022/188 as a novel food ingredient. House cricket holds promise as a sustainable alternative to traditional farming and conventional food sources due to its nutritional and pharmaceutical properties Abstract Entomophagy (consumption of insects) has been ...

Differential temporal release and lipoprotein loading in B. thetaiotaomicron bacterial extracellular vesicles

Journal of Extracellular Vesicles, Volume 13, Issue 1, January 2024.
Abstract Bacterial extracellular vesicles (BEVs) contribute to stress responses, quorum sensing, biofilm formation and interspecies and interkingdom communication. However, the factors that regulate their release and heterogeneity are not well understood.

Deciphering the metabolic interactions between mucus associated Ruminococcus gnavus and Limosilactobacillus reuteri strains [PDF]

Cross-feeding between gut microbiota members is crucial for maintaining gut homeostasis. Cobamides, the vitamin B12 family of enzyme cofactors, are synthesised by approximately 25% of gut microbes while 80% rely on cobamides to conduct enzymatic ...

Cobamide remodeling in the freshwater microalga Chlamydomonas reinhardtii

FEMS Microbiology Letters, 2020
ABSTRACTMicroalgae are not able to produce cobamides (Cbas, B12 vitamers) de novo. Hence, the production of catalytically active Cba-containing methionine synthase (MetH), which is present in selected representatives, is dependent on the availability of exogenous B12 vitamers.

Supplementation with Pentadecylresorcinol to a High-Fat Diet Increases the Predicted Representation of Enzymes and Metabolic Pathways for Vitamin B12 Synthesis by the Gut Microbiota Of C57bl6 Mice

Ожирение и метаболизм
5-Pentadecylresorcinol (C15) is a natural alkylresorcinol that has been shown to protect against complications caused by imbalanced nutrition. Although the exact mechanisms of beneficial activity of C15 are not known, we assume that the protective ...

Uneven distribution of cobamide biosynthesis and dependence in bacteria predicted by comparative genomics [PDF]

, 2019
The vitamin B12 family of cofactors known as cobamides are essential for a variety of microbial metabolisms. We used comparative genomics of 11,000 bacterial species to analyze the extent and distribution of cobamide production and use across bacteria ...

Structural Insights into the Function of the Nicotinate Mononucleotide:phenol/p‑cresol Phosphoribosyltransferase (ArsAB) Enzyme from Sporomusa ovata

, 2016
Cobamides (Cbas) are cobalt (Co) containing tetrapyrrole-derivatives involved in enzyme-catalyzed carbon skeleton rearrangements, methyl-group transfers, and reductive dehalogenation. The biosynthesis of cobamides is complex and is only performed by some

Cobamide Structure Depends on Both Lower Ligand Availability and CobT Substrate Specificity [PDF]

, 2013
SummaryCobamides are members of the vitamin B12 family of cofactors that function in a variety of metabolic processes and are synthesized only by prokaryotes. Cobamides produced by different organisms vary in the structure of the lower axial ligand. Here
