A new family of very long chain alpha,omega-dicarboxylic acids is a major structural fatty acyl component of the membrane lipids of Thermoanaerobacter ethanolicus 39E.

Journal of Lipid Research, 1994
A new family of alpha,omega-dicarboxylic, very long chain fatty acids was isolated and characterized from the lipids of thermophilic anaerobic eubacterium, Thermoanaerobacter ethanolicus 39E. After the isolation of the membrane, the fatty acyl components

The Thermoanaerobacter glycobiome reveals mechanisms of pentose and hexose co-utilization in bacteria. [PDF]

PLoS Genetics, 2011
Thermoanaerobic bacteria are of interest in cellulosic-biofuel production, due to their simultaneous pentose and hexose utilization (co-utilization) and thermophilic nature. In this study, we experimentally reconstructed the structure and dynamics of the

Metabolic engineering of Clostridium thermocellum for n-butanol production from cellulose

Biotechnology for Biofuels, 2019
Background Biofuel production from plant cell walls offers the potential for sustainable and economically attractive alternatives to petroleum-based products. In particular, Clostridium thermocellum is a promising host for consolidated bioprocessing (CBP)

Formate-driven H2 production by whole cells of Thermoanaerobacter kivui

Biotechnology for Biofuels and Bioproducts, 2022
Abstract Background In times of global warming there is an urgent need to replace fossil fuel-based energy vectors by less carbon dioxide (CO2)-emitting alternatives. One attractive option is the use of molecular hydrogen (H2) since its combustion emits water (H2O) and not CO2.

Ethanol production by the hyperthermophilic archaeon Pyrococcus furiosus by expression of bacterial bifunctional alcohol dehydrogenases

Microbial Biotechnology, 2017
Summary Ethanol is an important target for the renewable production of liquid transportation fuels. It can be produced biologically from pyruvate, via pyruvate decarboxylase, or from acetyl‐CoA, by alcohol dehydrogenase E (AdhE).

S‐Adenosyl‐d‐Methionine as a Non‐Physiological Substrate for a Wide Range of SAM‐Dependent Enzymes

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
From methylation and cyclisation to radical chemistry, diverse enzyme classes utilise the non‐canonical cofactor d‐SAM. These findings reveal an unexpected tolerance of SAM‐dependent catalysis towards inversion of the methionine Cα stereocentre. The ability of SAM‐dependent enzymes to accept S‐adenosyl‐d‐methionine [d‐SAM, (SS,RCα)‐SAM] instead of the ...

Stereoselective Production of Fluorohydrins Biocatalyzed by an Alcohol Dehydrogenase From Pichia glucozyma

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Ketoreductase from Pichia glucozyma (KRED1‐Pglu) has been successfully employed for the stereoselective bioreduction of α‐halogenated ketones using the purified protein, or alternatively a lyophilized whole cell preparation overexpressed in E. coli. Better chemoselectivities were found with pure biocatalyst, obtaining a series of chiral fluorohydrins ...

Simultaneous expression of an endogenous spermidine synthase and a butanol dehydrogenase from Thermoanaerobacter pseudethanolicus in Clostridium thermocellum results in increased resistance to acetic acid and furans, increased ethanol production and an increase in thermotolerance

Biotechnology for Biofuels and Bioproducts, 2023
Background Sensitivity to inhibitors derived from the pretreatment of plant biomass is a barrier to the consolidated bioprocessing of these complex substrates to fuels and chemicals by microbes.
