Biological conversion of carbon monoxide: rich syngas or waste gases to bioethanol [PDF]

, 2011
Bioconversion of syngas/waste gas components to produce ethanol appears to be a promising alternative compared to the existing chemical techniques. Recently, several laboratory-scale studies have demonstrated the use of acetogens that have the ability to

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

Novel molecular markers for the detection of methanogens and phylogenetic analyses of methanogenic communities

Frontiers in Microbiology, 2015
Methanogenic Archaea produce approximately one billion tons of methane annually, but their biology remains largely unknown. This is partially due to the large phylogenetic and phenotypic diversity of this group of organisms, which inhabit various anoxic ...

Comparative metagenomics of three Dehalococcoides-containing enrichment cultures: the role of the non-dechlorinating community

BMC Genomics, 2012
Background The Dehalococcoides are strictly anaerobic bacteria that gain metabolic energy via the oxidation of H2 coupled to the reduction of halogenated organic compounds. Dehalococcoides spp.

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 ...

Evolutionary Trajectories of Methionine Metabolism in Mycobacterium and Its Application to Engineer a Vitamin B12 Whole‐Cell Ribosensor

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.

Lettuce fortification through vitamin B12‐producing bacteria – proof of concept study

Journal of the Science of Food and Agriculture, Volume 105, Issue 6, Page 3343-3354, April 2025.
Abstract BACKGROUND Vitamin B12 (cobalamin) can be produced de novo only by certain bacteria and archaea. It plays a crucial role in the health of animals and humans, which obtain it only through diet, mainly from animal products. This study aimed to identify endophytic bacterial strains capable of synthesizing vitamin B12 and enriching edible plants ...
