“…Furthermore, in our experiment, Fe 2+ and Mn 2+ played only minor roles in the fermentation, which is different from the report of Laube et al. . They reported that single or combined addition of Fe 2+ and Mn 2+ would show higher yields of 2,3‐BD.…”

Corncob residue, a waste in xylose or xylitol production, was utilized to produce 2,3-butanediol (2,3-BD) via simultaneous saccharification and fermentation (SSF). This study developed the optimal conditions for production of 2,3-BD by using a heat-resistant strain, Enterobacter cloacae UV4, to perform SSF of the corncob residue. Urea, lactic acid, sodium citrate, and MgSO4 , selected by the Plackett-Burman experiment, were determined to be significant independent variables to conduct the response surface experiment. With the optimized medium, a total production of 28.923 g/L for 2,3-BD and acetoin (BA) was obtained at 60 H. Furthermore, 43.162 g/L of BA production and 0.553 g/L/H of productivity were obtained by fed-batch SSF, which was 0.424 g diol/g consumed corncob residue. The results suggest that the waste corncob residue could be used as an available substrate for the production of 2,3-BD by E. cloacae UV4, as well as a potential resource to improve the economics of microbial compound production.

“…However, optimum production was observed with 1.5 : < YE in the same fermentation system when the glucose concentration was increased to 5 %. 47 Yu & Saddler4' also observed increased yield of 2,3-butanediol with 1 : < YE in the fermentation of Klebsiellu pneumoniae. Like yeast extract, pH seems to influence 2,3-butanediol production.'…”

Most studies on 23-butanediol production by microbial jermentution have been carried out using Klebsiella oxytoca and Bacillus polymyxa. In these jermentations there is a signiJicant conversion of carbon source into ethanol, glycerol and various organic acids as by-products. On the other hand, this investigation has shown that the major products of ]ermentation by Bacillus amyloliquefaciens are 2,3-butanediol and some minor acids. In a typictrl fermentation about 33 g of butanediol was produced jrom 100 g of glucose.The ejfict of pH, vurious carbohydrate source, initial glucose concentration and ueration on the 2,3-butanediol jermentution by B. amyloliquefaciens were investigated. The butanediol productivity and yield was found to be highest with glucose as the carbohydrate source. The glucose concentration wus varied between 30 and 100 g dm-with oxygen transter rate controlled between 47.5 and 78.0 h -' . Oxygen and the initial substrate concentrations signijcantly influence the yield, productivity and by-product jormation.

“…15 In addition, for the nitrogen sources in 2,3-BDO fermentation, most of the previous works have used yeast extract or ammonium salts. 16,17 Because of their relatively high cost, the use of these nitrogen sources for the industrial production of 2,3-BDO may not be feasible. 18 Condensed distillers solubles (CDS) are a byproduct of BE production that is extensively used as a component of the medium for the culture of microorganisms in industrial fermentation.…”

BACKGROUND: For the efficient use of cassava as industrial material in the fermentation business, an integrated process was developed to produce 2,3-butanediol (2,3-BDO) and bioethanol (BE) by a highly efficient and economical method. After separating the liquefied cassava into a solid and a liquid part, the liquid part was used to produce 2,3-BDO, and the solid part was then used to produce BE. RESULTS:The integrated process efficiently fermented 1000 g of dried cassava to 288 g of 2,3-BDO (120.1 g L −1 titer and 2.39 L fermented broth) and 57 g of BE (38.4 g L −1 titer and 1.49 L fermented broth). Also, fermentable sugar of cassava was 100% available for this process, and the byproduct of BE production, condensed distillers solubles (CDS), was used as a potential nutrient source for the economical production of 2,3-BDO.CONCLUSION: An integrated process with simultaneous saccharification and fermentation (SSF), pH shift, and rpm shift was developed to enhance 2,3-BDO production and to reduce the production cost of 2,3-BDO and BE. The strategy of employing cassava as a starchy biomass-based biorefinery resource for 2,3-BDO and BE production was successfully performed.
