中文摘要Currently, the use of low-cost lignocellulosic biomass as an alternative substrate for 2,3-butanediol (2,3-BD) production to improve the economics of the process received considerable attention. But cellulose as the substrate required expensive cellulase, which increased the production costs. In this paper, hemicelluloses sugars were fractionated from corn stover by steam explosion. The objective of this study was to develop the corn stover hemicelluloses as carbon source to produce 2,3BD. After steam explosion, 69.81% of hemicelluloses were degraded to monosaccharide (glucose, xylose and arabinose) and oligosaccharide, meanwhile some by-products, such as acetic acid, furfural, 5-hydroxymethylfurfual (5-HMF) and soluble lignin compounds (SLC) were produced in the steam explosion process as well. Paenibacillus polymyxa S-07 could utilize all the hemicelluloses sugars to ferment 2,3-BD. Acetic acid could not only inhibit the production of by-products, but also promote the conversion of sugars to 2,3-BD. Compared with the fermentation without adding acetic acid, the concentration of 2,3-BD increased from 16.30 g/l to 22.41 g/l with adding 7 g/l acetic acid. Furfural and 5-HMF below 1 g/l promoted the production of 2,3-BD, and inhibited the production of 2,3-BD over 1 g/l. SLC was the inhibitor in the hemicelluloses extract. SLC over 2.62 g/l inhibited the growth of P. polymyxa S-07 severely. After detoxification of the extract with active carbon, SLC below 1.117 g/l almost had no effect on the production of 2,3-BD, the yield of 2,3-BD reached 12.07 g/l using the extract as carbon source, and the conversion rate of 2,3-BD was 0.42 g/g sugar. This study provides a potential feedstock for 2,3-butanediol production.
