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 ...

Purification and characterization of a thermostable beta-xylosidase from Thermoanaerobacter ethanolicus [PDF]

Journal of Bacteriology, 1992
A highly thermostable beta-xylosidase, exhibiting similarly high activities for arylxylose and arylarabinose, was purified (72-fold) to gel electrophoretic homogeneity from the ethanologenic thermophilic anaerobe Thermoanaerobacter ethanolicus. The isoelectric point is pH 4.6; the apparent molecular weight is around 165,000 for the native enzyme (gel ...

Salt‐Driven Silk Fibroin Assembly for Solvent‐Free Multienzyme Co‐Immobilization

ChemCatChem, Volume 18, Issue 12, 26 June 2026.
Salt‐induced silk fibroin assembly enables solvent‐free co‐immobilization of redox enzyme cascades in fully aqueous media without covalent modification. The protein matrix provides high operational stability and modulates cofactor accessibility, enhancing functional coupling within the confined microenvironment.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Thermoanaerobacter sp. CGTase: Its Properties and Application.

Journal of the Japanese Society of Starch Science, 1992
A novel CGTase (Cyclomaltodextrin glucanotransferase) has been isolated from a strain of Thermoanaerobacter, a thermophilic anaerobe. The enzyme is extremely heat stable and has a temperature optimum of 90-95°C at pH 6.0. It is active over a broad pH range, and exhibits more than 80% activity from pH 5.0-6.7.

Substrate Walking for Selective Ene Reduction

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Ene‐reductases (EREDs) efficiently reduce activated C═C bonds. Expanding the current application, they catalyze the selective reduction of highly substituted cyclohexenones. Immobilized, they were scaled to 200 mL, achieving full substrate conversion without enzyme degradation. ABSTRACT Ene‐reductases (EREDs) efficiently reduce activated C═C bonds, but

Three novel oligosaccharides synthesized using Thermoanaerobacter brockii kojibiose phosphorylase

Chemistry Central Journal, 2007
Background Recently synthesized novel oligosaccharides have been produced primarily by hydrolases and glycosyltransferases, while phosphorylases have also been subject of few studies.

Optimization of Regioselective α-Glucosylation of Hesperetin Catalyzed by Cyclodextrin Glucanotransferase

Molecules, 2018
The regioselective α-glucosylation of hesperetin was achieved by a transglycosylation reaction catalyzed by cyclodextrin glucanotransferase (CGTase) from Thermoanaerobacter sp. using soluble starch as glucosyl donor.
