Efficient conversion of hemicellulose into 2, 3-butanediol by engineered psychrotrophic Raoultella terrigena: mechanism and efficiency

Bioresource Technology, 2022
Low-temperature biorefineries inhibit the multiplication of undesired microorganisms, improve product purity and reduce economic costs. Herein, to improve the 2,3-butanediol (2,3-BD) bioconversion efficiency from hemicellulose, a psychrotrophic hemicellulose-degrading strain Raoultella terrigena HC6 with high β-xylosidase activity 1520 U/mL was ...

Engineering of glycerol dehydrogenase for improved activity towards 1, 3-butanediol

Applied Microbiology and Biotechnology, 2010
The objective of this study was to use protein engineering techniques to enhance the catalytic activity of glycerol dehydrogenase (GlyDH) on racemic 1, 3-butanediol (1, 3-BDO) for the bioproduction of the important pharmaceutical intermediate 4-hydroxy-2-butanone.

Isolation and identification of an osmotolerant Bacillus amyloliquefaciens strain T4 for 2, 3-butanediol production with tobacco waste

Preparative Biochemistry & Biotechnology, 2021
Microbial biomass and waste materials conversion for biochemicals production has been an alternative for energy conservation and emission reduction. While toxic substances in biomass materials and high osmotic pressure formed in fermentation-based systems block the bioconversion processes of microorganisms. In the present study, strain T4 that isolated

2, 3-Butanediol activated disease-resistance of creeping bentgrass by inducing phytohormone and antioxidant responses

Plant Physiology and Biochemistry, 2018
Brown patch, caused by Rhizoctonia solani, is a serious disease in Agrostis stolonifera. 2, 3-butanediol (2, 3-BD) is the major component of volatile organic compounds and was found to initiate induced systemic resistance (ISR). To investigate the induced resistance mechanism of 2, 3-BD, we examined the effects of resistance by area affected, along ...

Heat Capacities of Aqueous Solutions of Ethylene Glycol, Propylene Glycol and 1, 3-Butanediol

NIPPON KAGAKU KAISHI, 1972
A calorimerter composed of a Dewar vessel and a Beckmann thermometer was constructed. By means of this calorimeter, the heat capacities of aqueous solutions of ethylene glycol, propyrene glycol, and butanediol were measured at 30d C. It was confirmed by the measurement of heat capacities of n-heptane that the errors due to the evaporation were ...

[Production of 2, 3-butanediol and succinic acid by Salinivibrio YS].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2013
The production of 2, 3-butanediol and succinic acid by a moderate halophile under anaerobic condition was investigated. This halophile, termed Salinivibrio YS, was isolated from the solid samples collected from Aydingkol Lake. Based on the single factor experiment, the parameters and their values for the production were obtained.

Segmented block copolymers of natural rubber and 1, 3-butanediol–toluene diisocyanate oligomers

Polymer, 1998
Abstract A series of segmented block copolymers of NR and 1,3-butanediol–toluene diisocyanate oligomers have been synthesized with varying hard segment content. The synthesis has been carried out by one-shot and two-shot processes in solution. The products were characterized by spectral analysis, thermal and mechanical analysis, SEM and optical ...

Engineering Klebsiella oxytoca for efficient 2, 3-butanediol production through insertional inactivation of acetaldehyde dehydrogenase gene

Applied Microbiology and Biotechnology, 2009
Ethanol was a major byproduct of 2,3-butanediol (2,3-BD) fermentation by Klebsiella oxytoca ME-UD-3. In order to achieve a high efficiency of 2,3-BD production, K. oxytoca mutants deficient in ethanol formation were successfully constructed by replace the aldA gene coding for aldehyde dehydrogenase with a tetracycline resistance cassette.

Synthesis, design and optimization of alternatives to purify 2, 3-Butanediol considering economic, environmental and safety issues

Sustainable Production and Consumption, 2019
Abstract 2,3-Butanediol is a promising chemical due to its several applications. Nowadays, 2,3-Butanediol is produced by a chemical process. However, it is also produced by microbial production. Several metabolic strategies attempt to enhance the production of 2,3-Butanediol; yet, the recovery of 2,3-Butanediol from the fermentation broth is yet a ...
