TL;DR: In this article, a microorganism having 2,3-butanediol production ability, modified to decrease the activity of: a) lactate dehydrogenase; b) one of or both of acetate kinase and phosphotransacetylase; and c) CoA transferase, in comparison with the not-modified strain.
Abstract: PROBLEM TO BE SOLVED: To provide microorganisms for efficient and safe production of 2,3-butanediol, where decrease in the microbial growth rate is prevented and byproduct is formed less.SOLUTION: Provided is a microorganism having 2,3-butanediol production ability, modified to decrease the activity of: a) lactate dehydrogenase; b) one of or both of acetate kinase and phosphotransacetylase; and c) CoA transferase, in comparison with the not-modified strain.

TL;DR: The production of 2,3-butanediol from fermentation of xylose by Klebsiella oxytoca ZU-03 was carried out in this article, in which xyloses was the main reducing sugar in hemicellulosic hydrolysate.
Abstract: The production of 2,3-butanediol was carried out from fermentation of xylose by Klebsiella oxytoca ZU-03,in which xylose was the main reducing sugar in hemicellulosic hydrolysate.Under optimized conditions: xylose mass concentration 90 g/L,corn liquor mass concentration 6 g/L,inoculum 10 %(volume fraction),initial pH value 5.5 and 30 ℃,concentration of 2,3-butanediol reached 36.22 g/L and yield of 2,3-butanediol from xylose was 0.45 g/g.

TL;DR: In this paper, a method for selectively producing 3-hydroxyl-2-butanone and 2, 3-butanediol by using an environmental safety bacterial strain Bacillus amyloliquefaciens with the CCTCC NO. M2012349 and changing the content of corn steep liquor in a medium, the stirring speed and the ventilation capacity, is described.
Abstract: The invention discloses a method for selectively producing 3-hydroxyl-2-butanone and 2, 3-butanediol by using an environmental safety bacterial strain Bacillus amyloliquefaciens with the CCTCC NO. M2012349 and changing the content of corn steep liquor in a medium, the stirring speed and the ventilation capacity, and belongs to the field of a fermentation technology in biological engineering. The method is characterized in that when the 3-hydroxyl-2-butanone is mainly synthesized, the concentration of the corn steep liquor in the fermentation medium can be reduced to be more than or equal to 5g/L, and the relatively high dissolved oxygen level (the air mass flow is 240m /h.m medium, and the stirring rotating speed is 450r/min) is maintained in a fermentation process; and when the 2, 3-butanediol is synthesized, the concentration of the corn steep liquor in the fermentation medium can be increased to be more than or equal to 40g/l, the relatively low dissolved oxygen level (the air mass flow is 120m /h.m medium, and the stirring rotating speed is 350r/min) is maintained in a fermentation process.
