Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

Advanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Cloning and Optimization of Formate Dehydrogenase Gene Expression in E. COLI [PDF]

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd
Introduction: The increase in greenhouse gas levels and the gradual warming of the earth have garnered worldwide interest. The enzyme formate-dehydrogenase can reduce CO2 by converting it into formate, which is subsequently converted into methanol by the

Physiological Effects of 2-Bromoethanesulfonate on Hydrogenotrophic Pure and Mixed Cultures

Microorganisms, 2022
Mixed or pure cultures can be used for biomethanation of hydrogen. Sodium 2-bromoethanesulfonate (BES) is an inhibitor of methanogenesis used to investigate competing reactions like homoacetogenesis in mixed cultures.

How FocA facilitates fermentation and respiration of formate by Escherichia coli

Journal of Bacteriology
Formic acid is an important source of reductant and energy for many microorganisms. Formate is also produced as a fermentation product, e.g., by enterobacteria like Escherichia coli.

Process Study on the Enzyme-Catalyzed Preparation of Key Chiral Intermediates for Saxagliptin

Pharmaceutical Fronts, 2022
Saxagliptin is a therapeutic drug for diabetes. The key synthesis process of the drug involves catalyzing 2-(3-hydroxy-1-adamantyl)-2-oxoacetic acid (A) into (S)-3-hydroxyadamantane glycine (B), during which enzymes phenylalanine dehydrogenase mutant ...

Comparative genomics and mutagenesis analyses of choline metabolism in the marine Roseobacter clade [PDF]

, 2015
Choline is ubiquitous in marine eukaryotes and appears to be widely distributed in surface marine waters; however, its metabolism by marine bacteria is poorly understood.

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

Asia-Pacific Journal of Chemical Engineering, EarlyView.
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 ...

Kinetics for formate dehydrogenase of Escherichia coli formate-hydrogenlyase

Journal of Biological Chemistry, 1991
Kinetic parameters of the selenium-containing, formate dehydrogenase component of the Escherichia coli formate-hydrogenlyase complex have been determined with purified enzyme. A ping-pong Bi Bi kinetic mechanism was observed. The Km for formate is 26 mM, and the Km for the electron-accepting dye, benzyl viologen, is in the range 1-5 mM.

Two‐Step Synthesis of a Chiral Fluorinated Alcohol With Silica‐Supported Enzyme RrADH in Batch and Continuous Flow Mode

Chemistry – A European Journal, EarlyView.
A two‐step process was transferred from batch to flow mode for the synthesis of (R)‐2‐fluoro‐1‐phenylethanol as a benchmark, consisting of a decarboxylative fluorination in aqueous media, followed by an enantioselective biocatalytic reduction of the prochiral intermediate with RrADH immobilized on silica supraparticles.
