A Downstream Processing Cascade for Separation of Caproic and Caprylic Acid from Maize Silage-Based Fermentation Broth

Frontiers in Bioengineering and Biotechnology, 2021
Production of caproic and caprylic acid through anaerobic fermentation of crops or residual and waste biomass has been regarded as an alternative to the conventional ways, where plant oils and animal fats are mostly used. The downstream processing of the

Glucosinolate biosynthesis: demonstration and characterization of the condensing enzyme of the chain elongation cycle in Eruca sativa

, 2004
Glucosinolates are a group of sulfur-rich thioglucoside natural products common in the Brassicaceae and related plant families. The first phase in the formation of many glucosinolates involves the chain extension of the amino acid methionine.

Ethanol:propionate ratio drives product selectivity in odd-chain elongation with Clostridium kluyveri and mixed communities

, 2020
Microbial production of valerate, a five-carbon carboxylate, can occur from propionate and ethanol through a process called odd-chain elongation. The generation of even-chain compounds in this process lowers product selectivity, forming a key challenge ...

The potential of caproate (hexanoate) production using Clostridium kluyveri syntrophic cocultures with Clostridium acetobutylicum or Clostridium saccharolyticum

Frontiers in Bioengineering and Biotechnology, 2022
Caproate (hexanoate) and other medium-chain fatty acids are valuable platform chemicals produced by processes utilizing petroleum or plant oil. Clostridium kluyveri, growing on short chain alcohols (notably ethanol) and carboxylic acids (such as acetate)

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The Direction of Glycan Chain Elongation by Peptidoglycan Glycosyltransferases [PDF]

Journal of the American Chemical Society, 2007
Peptidoglycan glycosyltransferases (PGTs) are highly conserved enzymes that catalyze the polymerization of Lipid II to form the glycan strands of bacterial murein. Because they play a key role in bacterial cell wall synthesis, these enzymes are potentially important antibiotic targets; however, their mechanisms are not yet understood.

The Isolate Caproiciproducens sp. 7D4C2 Produces n-Caproate at Mildly Acidic Conditions From Hexoses: Genome and rBOX Comparison With Related Strains and Chain-Elongating Bacteria

Frontiers in Microbiology, 2021
Bulk production of medium-chain carboxylates (MCCs) with 6–12 carbon atoms is of great interest to biotechnology. Open cultures (e.g., reactor microbiomes) have been utilized to generate MCCs in bioreactors.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Methanol based elongation of propionate and propionate and acetate in continuous and batch mixed culture systems

, 2019
Continuous methanol based chain elongation of propionate to n-valerate was performed in a mixed culture reactor. Additionally, the study shows simultaneous methanol based elongation of propionate and acetate to respectively n-valerate and iso/n-butyrate ...

Continuous Production of Ethanol, 1-Butanol and 1-Hexanol from CO with a Synthetic Co-Culture of Clostridia Applying a Cascade of Stirred-Tank Bioreactors

Microorganisms, 2023
Syngas fermentation with clostridial co-cultures is promising for the conversion of CO to alcohols. A CO sensitivity study with Clostridium kluyveri monocultures in batch operated stirred-tank bioreactors revealed total growth inhibition of C.
