2-Butanol and Butanone Production in Saccharomyces cerevisiae …

23/7/2014· the main aim of this project was to evaluate the possibility of producing 2-butanol from meso -2,3-butanediol in saccharomyces cerevisiae ( figure 1 ), as a safe microorganism with a long history of industrial usage. 2,3-butanediol is known to be produced in s. cerevisiae, in low amounts, and there are a nuer of reports on its production …

CA2565675A1 - Process for the preparation of 2-butanol - Google

The 2-butanone/S-2-butanol mixture was first obtained from the heptanol phase (boiling point approx. 158-161 C) via distillation prior to the separation of 2-butanone (boiling point 80

Production of 2-butanol through meso -2, 3-butanediol consumption in lactic acid bacteria …

1/11/2014· The isolates, SE20 and SE31, were found to be the best 2-butanol producers with about 0.8 g L −1 2-butanol produced after 7 days (equivalent to conversion yield of 0.8 g g −1 of 2, 3-butanediol), while the strain reported to show the highest production in a previous study (Speranza et al ., 1996 ), LB 734, produced 0.29 g L −1.

2-Butanol - Wikipedia

Although some 2-butanol is used as a solvent, it is mainly converted to butanone (methyl ethyl ketone, MEK), an important industrial solvent and found in many domestic cleaning agents and paint removers. Though most paint removers have ceased using MEK in their products due to health concerns and new laws.

Metabolic Engineering of Klebsiella pneumoniae for the Production of 2-Butanone …

14/10/2015· 2-Butanone is an important commodity chemical of wide appliion in different areas. In this study, Klebsiella pneumoniae was engineered to directly produce 2-butanone from glucose by extending its native 2, 3-butanediol synthesis pathway. To identify the potential enzyme for the efficient conversion of 2, 3-butanediol to 2-butanone, we screened different …

First, a small difference in selectivity is seen for the non- cavitating ultrasound compared to the control experiment (obtained from the inverse of the ratio of lifetimes). For example, the ratio of 2-butanone to 2- butanol products for the stirred without 1-pentanol is 0.74 (equal to 60.7/82.0). Second, comparing these values to the
