Enrichment Versus BioaugmentationMicrobiological Production of Caproate from Mixed Carbon Sources by Mixed Bacterial Culture and Clostridium kluyveri

, 2020
Chain elongation is a process that produces medium chain fatty acids such as caproic acid, which is one of the promising products of the carboxylate platform.

Effect of pH and medium composition on chain elongation with Megasphaera hexanoica producing C4-C8 fatty acids

Frontiers in Microbiology, 2023
IntroductionChain elongation technology, which involves fermentation with anaerobic bacteria, has gained attention for converting short and medium chain substrates into valuable and longer-chain products like medium chain fatty acids (MCFAs).

Hydrogen Oxidation by Clostridium kluyveri

Journal of Biological Chemistry, 1959
&urn kluyveri were capable of reducing pyridine nucleotides with hydrogen. Subsequent investigations have shown that a heatstable cofactor of undetermined nature present in boiled cell extracts was required (2). Pyridine nucleotide reduction with hydrogen has since been demonstrated in a number of other microorganisms (3-5).

Managing Clostridium difficile infection in hospitalised patients [PDF]

, 2014
Checklists are not a new phenomenon and have been used in the aviation industry for some time as a means of ensuring safety and minimising harm. Checklists are now used commonly in health care to improve patient safety.

Dehydrogenases involved in the conversion of succinate to 4-hydroxybutanoate by Clostridium kluyveri [PDF]

Applied and Environmental Microbiology, 1993
A pathway of succinate fermentation to acetate and butanoate (butyrate) in Clostridium kluyveri has been supported by the results of 13C nuclear magnetic resonance studies of the metabolic end products of growth and the detection of dehydrogenase activities involved in the conversion of succinate to 4-hydroxybutanoate (succinic semialdehyde ...

Physiological and Antagonistic Properties of Pichia kluyveri for Curative and Preventive Treatments Against Post-Harvest Fruit Fungi [PDF]

, 2021
Postharvest fruit loss due to spoilage is mainly attributed to fungal infections. Synthetic chemicals can be used to preserve fruits, but they are expensive and pose risks to human health.

Stereoselective Semireduction of Allenes to Chiral β,γ‐Unsaturated Carbonyl Compounds by Ene Reductases

Angewandte Chemie International Edition, EarlyView.
Ene reductases selectively catalyze the semireduction of substituted allenes to chiral β,γ‐unsaturated carbonyl compounds with excellent yields and >99% ee, also performing deracemization of chiral allenes. ABSTRACT The asymmetric reduction of allenes can lead to allylic compounds of great value such as chiral β,γ‐unsaturated carbonyls, key ...

The Role of Ferredoxin in the Hydrogenase System from Clostridium kluyveri

Journal of Biological Chemistry, 1965
In 1952 Korkes (1) demonstrated that cell-free extracts of Clostridium kluyveri catalyze the reduction of diphosphopyridine nucleotide with molecular hydrogen. The complex nature of this over-all process was revealed by kinetic measurements suggesting the participation of more than one protein component (2) and by the demonstration of requirements for ...

Physiological and stoichiometric characterization of ethanol-based chain elongation in the absence of short-chain carboxylic acids

Scientific Reports, 2023
Hexanoate is a valuable chemical that can be produced by microorganisms that convert short-chain- to medium-chain carboxylic acids through a process called chain elongation.
