“…As shown in Table 2, 2,3-BD was found to increase with increasing initial glucose concentrations, but the specific 2,3-BD productivity decreased at high substrate concentrations, which indicated that at low sugar concentrations the fermentation proceeded rapidly to completion, on the other hand, higher glucose concentrations fermentations were less efficient. Similar results were reported by Laube et al [15] and Fages et al [16] for B. polymyxa fermentation, Alam et al [17] for B. amyloliquefaciens and Perego [18] for E. aerogenes.…”

In the current study, a GRAS (Generally Recognized As Safe) strain of Bacillus amyloliquefaciens producing 2,3-butanediol (2,3-BD) designated as B10-127 was isolated in our lab. The strain B10-127 produced 2,3-BD effectively under the condition of 20% glucose (quality concentration), showed a high-glucose tolerance. The effects of initial glucose concentration, temperature, pH and agitation on 2,3-BD production were investigated in this work and the proper parameters were identified. Accordingly, the fed-batch culture of B10-127 in larger scales (5 l) showed a remarkable 2,3-BD producing potency. The maximum 2,3-BD concentration reached 92.3 g/l at 96 h with a 2,3-BD productivity of 0.96 g/l h. To our knowledge, the results were new records on 2,3-BD fermentation by Bacillus, which shown an excellent candidate for the microbial fermentation of 2,3-BD on an industrial scale.

“…In contrast, there is little room for yield improvement, since as much as 95% of the energy in the substrate can be recovered in products with current technologies. 2,3‐Butanediol is a bulk chemical employed as antifreezing agent, solvent, fuel, fuel additive, as an intermediate for the manufacture of chemicals and as a building block for synthetic polymers and resins. It can be produced from xylose or xylose‐containing hydrolyzates by Klebsiella pneumoniae or Klebsiella oxytoca 27,28 at 90% of the theoretical yield (0.5 g/g), or from mannose with Bacillus polymyxa 29. Product recovery is desirably carried out by extraction instead distillation, owing to its high boiling point. 1,3‐Propanediol, also called β‐propylene glycol, is used as a solvent, in the manufacture of adhesives and polyesters, and as a building block for the production of polymers such as polytrimethylene terephthalate.…”

The aqueous fractionation of native lignocellulosic materials with hot, compressed water (also known as hydrothermal processing or autohydrolysis) has been proposed as a fractionation method for biorefineries, as it enables the simultaneous removal of water‐soluble extractives and the solubilization of hemicelluloses, yielding a solid phase enriched in lignin and cellulose. When the operation is carried out under favorable conditions, the liquid phase from autohydrolysis contains valuable products derived from hemicelluloses, including oligosaccharides that keep the major structural features of the polymer (including substitution by acetyl groups). Post‐hydrolysis of oligosaccharides in media catalyzed by acids or enzymes yields fermentable media containing hemicellulosic sugars; whereas harsh acid hydrolysis conditions result in the production of levulinic acid. Subsequent delignification of autohydrolyzed solids enables the separation of the three major lignocellulose components (hemicelluloses, cellulose, and lignin). As an alternative way for using autohydrolyzed solids, they can be used as substrates for the enzymatic hydrolysis of cellulose, leaving lignin as a solid by‐product. The sustainable manufacture of materials, fuels and chemicals from the biorefinery schemes cited above is discussed. Particular attention is paid to hemicellulose‐derived products. © 2011 Society of Chemical Industry and John Wiley & Sons Ltd

“…In the comparison of productivity with different bacteria species and substrates shown in Table 6, it was found that with the optimal medium, BA production and productivity were higher than with other media in batch fermentation (Grover et al, 1990;Cao et al, 1997;Jiang et al, 2013). Compared with the utilization of xylose, BA production in this study was higher than in other studies (Jansen et al, 1984;Laube et al, 1984). In fed-batch fermentation, BA production with xylose solution was lower than with glucose or other pure substrates (Ji et al, 2010;Zhang et al, 2010).…”

During the process of industrial production of biofuels and biochemicals from lignocellulosic biomass, large amounts of waste byproducts rich in xylose are generated, resulting in excessive wastage of natural resources and environmental pollution. In this work, xylose solution from corncob hydrolysate was utilized to produce 2,3-butanediol (2,3-BD), using the strain Enterobacter cloacae CICC 10011 to improve the utilization rate of hemicellulose and reduce environmental pollution. 2,3-BD fermentation conditions were subsequently developed. Xylose solution and (NH 4 ) 2 HPO 4 , selected with the Plackett-Burman experiment, were determined as significant independent variables to conduct a response surface experiment. With the optimized medium, 50.02 g/L 2,3-BD production was obtained, which corresponded to 85.16% of the theoretical value. Furthermore, 81.4 g/L 2,3-BD production, 92.95 g/L the total production (2,3-BD + acetoin), and 0.72 g/(L h) productivity were obtained by fed-batch fermentation. Therefore, efficient production of 2,3-BD from corncob-derived xylose is important in the future development and expansion of biorefining technologies.
