Cyanobacterial conversion of carbon dioxide to 2,3-butanediol [PDF]

Proceedings of the National Academy of Sciences, 2013
Conversion of CO 2 for the synthesis of chemicals by photosynthetic organisms is an attractive target for establishing independence from fossil reserves. However, synthetic pathway construction in cyanobacteria is still in its infancy compared with model fermentative organisms. Here we systematically developed the 2,

Improved xylose tolerance and 2,3-butanediol production of Klebsiella pneumoniae by directed evolution of rpoD and the mechanisms revealed by transcriptomics

Biotechnology for Biofuels, 2018
Background The biological production of 2,3-butanediol from xylose-rich raw materials from Klebsiella pneumoniae is a low-cost process. RpoD, an encoding gene of the sigma factor, is the key element in global transcription machinery engineering and has ...

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

Draft genome sequence of tetracycline-resistant Klebsiella oxytoca CCTCC M207023 producing 2,3-butanediol isolated from China

Journal of Global Antimicrobial Resistance, 2020
Objectives: Recently, the Gram-negative bacterium Klebsiella oxytoca has been identified as an emerging pathogen. Here we report the draft genome of a 2,3-butanediol-producing strain, K. oxytoca CCTCC M207023, isolated from soil in Nanjing, China.

Deletion of meso-2,3-butanediol dehydrogenase gene bud C for enhanced D-2,3-butanediol production in Bacillus licheniformis [PDF]

Biotechnology for Biofuels, 2014
D-2,3-butanediol has many industrial applications such as chiral reagents, solvents, anti-freeze agents, and low freezing point fuels. Traditional D-2,3-butanediol producing microorganisms, such as Klebsiella pneumonia and K. xoytoca, are pathogenic and not capable of producing D-2,3-butanediol at high optical purity.

Characterization of Cantaloupe, Grape, Pumpkin, and Tomato Seed Oils From Xinjiang: Oxidative Stability, Volatile‐Compound Analysis, and Sensory Evaluation

Food Chemistry International, EarlyView.
This study compares oxidative stability, fatty acid profiles, volatile compounds, and sensory attributes of four Xinjiang seed oils. Distinct aldehyde‐driven aroma patterns and compositional differences were revealed, providing a scientific basis for quality evaluation and valorization of underutilized plant seed oils in food applications.

2,3-butanediol in experimental myocardial ischaemia in pigs [PDF]

, 2017
To investigate the role of 2,3-butanediol in myocardial ischaemia we analysed this compound in pig's myocardium and blood. Ischaemia was induced by ligation of a coronary artery.
