TL;DR: The combination of zinc and nickel ions decrease the formation of 2,3 butanediol in the cultures of Aerobacter aerogenes and even with addition of milk this combination is not beneficial to the Formation of the diol.
Abstract: The presence of a small concentration of nickel or zinc ions in the cultures ofAerobacter aerogenes increases the formation of 2,3 butanediol in the cultures. The presence of 1 per cent of milk increases the formation of 2,3 butanediol in the cultures and decreases the consumption of sugar. Copper ions inhibit the formation of 2,3 butanediol. The combination of zinc and nickel ions decrease the formation of 2,3 butanediol in the cultures ofAerobacter aerogenes and even with addition of milk this combination is not beneficial to the formation of the diol. Nickel in presence of milk increases the formation of 2,3 butanediol.

TL;DR: In this paper , an improved bioprocess for producing 2,3-BDO from agricultural and industrial residues, consequently resulting in a low CO2 emission bioprogrocess.
Abstract: The valorization of agricultural and industrial wastes for fuel and chemical production benefits environmental sustainability. 2, 3-Butanediol (2,3-BDO) is a value-added platform chemical covering many industrial applications. Since the global market is increasing drastically, production rates have to increase. In order to replace the current petroleum-based 2,3-BDO production, renewable feedstock's ability has been studied for the past few decades. This study aims to find an improved bioprocess for producing 2,3-BDO from agricultural and industrial residues, consequently resulting in a low CO2 emission bioprocess. For this, screening of 13 different biomass samples for hydrolyzable sugars has been done. Alkali pretreatment has been performed with the processed biomass and enzyme hydrolysis performed using commercial cellulase. Among all biomass hydrolysate oat hull and spruce bark biomass could produce the maximum amount of total reducing sugars. Later oat hull and spruce bark biomass with maximum hydrolyzable sugars have been selected for submerged fermentation studies using Enterobacter cloacae SG1. After fermentation, 37.59 and 26.74 g/L of 2,3-BDO was obtained with oat hull and spruce bark biomass, respectively. The compositional analysis of each step of biomass processing has been performed and changes in each component have been evaluated. The compositional analysis has revealed that biomass composition has changed significantly after pretreatment and hydrolysis leading to a remarkable release of sugars which can be utilized by bacteria for 2,3-BDO production. The results have been found to be promising, showing the potential of waste biomass residues as a low-cost raw material for 2,3-BDO production and thus a new lead in an efficient waste management approach for less CO2 emission.

TL;DR: In this article, a reductive reaction in a hydrogen gas atmosphere in the presence of an inhomogeneous metal catalyst was used to convert 2-hydroxy-3-butanone to 2-3butanediol.
Abstract: PROBLEM TO BE SOLVED: To obtain 2,3-butanediol efficiently in a high yield from 3-hydroxy-2-butanone, especially by hydrogenation of an acetoin in a fermentation product obtained by biological fermentation.SOLUTION: A production method of 2,3-butanediol comprises subjecting a raw material containing 2-hydroxy-3-butanone to a reductive reaction in a hydrogen gas atmosphere in the presence an inhomogeneous metal catalyst to convert 2-hydroxy-3-butanone to 2,3-butanediol. The method especially improves the efficiency of the fermentation production of 2,3-butanediol by microorganisms.
