TL;DR: In this article, a method for producing acetoin and 2, 3- butanediol through high temperature fermentation has been proposed, with the advantages that raw materials are low in cost, the fermentation process is resistant to infectious microbe contamination, cooling water is saved, and operation is conducted coarsely.
Abstract: The invention discloses bacillus and application thereof to production of acetoin and 2, 3- butanediol through high temperature fermentation. A strain is Bacillus sp. H15-1CGMCC No. 12389, the gram faerbung is positive, spores are produced, the cellular morphology is in a rod shape, and the stain can grow at the temperature of 40-60 DEG C and proliferate at the highest speed at the temperature of 50 DEG C. By means of the strain, degerminated corn flour hydrolysate is adopted as the main raw material, a mechanical stirring and ventilation fermentation tank is adopted for conducting fermentation for 68 hours at the temperature of 50 DEG C, and acetoin with the concentration being 50.8 g/L and 2, 3- butanediol with the concentration being 32.1 g/L can be generated. A method for producing acetoin and 2, 3- butanediol through high temperature fermentation has the advantages that raw materials are low in cost, the fermentation process is resistant to infectious microbe contamination, cooling water is saved, and operation is conducted coarsely.

TL;DR: Pichia indica produces 2,3 butanediol during fermentation and this glycol increases with the presence of Zn++ in the culture, and on increasing the period of fermentation the glycol disappears from the culture.
Abstract: Pichia indica produces 2,3 butanediol during fermentation. The formation of this glycol increases with the presence of Zn++ in the culture. The increase of Zn++ concentration increases the formation of 2,3 butanediol in the culture till a maximum is reached. Further increase of Zn++ concentration decreases the diol production. On increasing the period of fermentation the glycol disappears from the culture.

TL;DR: In this article , the authors evaluated the dynamic properties of different separation schemes for the purification of 2,3-BD from biomass fermentation and found that thermal coupling in their topological design allows a general improvement of all sustainability indicators.
Abstract: Current social needs, as well as political and environmental restrictions, have led to the generation of products within a framework of sustainability, and favoring production processes based on renewable raw materials. During the process design work, the role of the dynamic properties of a process, together with some other metrics, is not always considered. However, several studies have shown that there is a certain relationship between the dynamics and controllability of the process and its sustainability. In this work, the dynamic properties of different separation schemes for the purification of 2,3-BD from biomass fermentation are evaluated. The study allowed determining the best alternatives for the eventual implementation of these schemes, as well as the role of controllability concerning other sustainability indicators. As result, it was found that schemes that include a thermal coupling in their topological design allow a general improvement of all sustainability indicators. In addition, it was observed in this case study that process intensification contributes significantly to the fulfillment of various sustainability indicators. • It was obtained the control properties of separation alternatives to purify 2,3-Butanediol, the thermally coupled alternatives resulted as the most balanced alternatives • The sustainable evaluation allows considering a thermal coupling as a fundamental step in process design of a sustainable process. • The most intensified alternative did not result as the most sustainable alternative
