Metabolism of 2,3‐butanediol in yeasts

Yeast, 1988
AbstractThe biochemistry and physiology of 2,3‐butanediol metabolism has been studied in a number of selected yeast species. Candida utilis CBS 621 exhibited diauxic growth on 2,3‐butanediol. The first phase was characterized bu the utilization of the two optically active stereoisomers and associated accumulatoin. In the second phase of growth the meso‐

Production of 2,3-butanediol by engineered Saccharomyces cerevisiae

Bioresource Technology, 2013
In order to produce 2,3-butanediol (2,3-BD) with a high titer, it is necessary to engineer Saccharomyces cerevisiae by deleting the competing pathway and overexpressing the 2,3-BD biosynthetic pathway. A pyruvate decarboxylase (Pdc)-deficient mutant was constructed and evolved for rapid glucose consumption without ethanol production.

Enhanced Production of 2,3-Butanediol from Sugarcane Molasses

Applied Biochemistry and Biotechnology, 2015
2,3-Butanediol has been known as a platform green chemical, and the production cost is the key problem for its large-scale production in which the carbon source occupies a major part. Sugarcane molasses is a by-product of sugar industry and considered as a cheap carbon source for biorefinery.

Adsorption of 2,3-butanediol on Si(1 0 0)

Surface Science, 2004
The adsorption of 2,3-butanediol on a Si(1 0 0) surface has been investigated by photoelectron spectroscopy. The valence band spectra show features assigned to molecular orbitals of 2,3-butanediol by comparison with calculations, and the surface states of clean Si are removed. The Si 2p reveals core-level shifts with two new components at 0.24 andc0.97

The Microbial Production of 2,3-Butanediol

1987
Publisher Summary This chapter provides a comprehensive survey of diol production, including biochemistry, microbiology, and process engineering. Two microbial species have demonstrated a potential for diol production on a commercial scale. Klebsiella pneumoniae, with broad substrate and environmental adaptability, is the most thoroughly investigated

Identification and measurement of 2,3‐butanediol in silage

Journal of the Science of Food and Agriculture, 1973
Abstract2,3‐butanediol was identified in silage extracts using gas chromatography and mass spectrometry. It was present in stacks of untreated and formaldehyde‐treated silage in concentrations of 2.4% of the dry matter.

Enhanced 2,3-butanediol production by Klebsiella pneumoniae SDM

Applied Microbiology and Biotechnology, 2009
Enhanced 2,3-butanediol (BD) production was carried out by Klebsiella pneumoniae SDM. The nutritional requirements for BD production by K. pneumoniae SDM were optimized statistically in shake flask fermentations. Corn steep liquor powder and (NH(4))(2)HPO(4) were identified as the most significant factors by the two-level Plackett-Burman design ...

Production of 2,3-butanediol from glucose byBacillus licheniformis

World Journal of Microbiology & Biotechnology, 1992
Bacillus licheniformis produced 2,3-butanediol from glucose with an optimum yield of 47 g/100 g glucose after 72 h of growth on a peptone/beef extract medium containing 2% (w/v) glucose at pH 6.0 and 37°C. This yield of 2,3-butanediol was higher than those previously reported forKlebsiella oxytoca (37 g/100 g glucose) andBacillus polymyxa (24 g/100 ...
