Abstract Butanol is a platform chemical that is utilized in a wide range of industrial products and is considered a suitable replacement or additive to liquid fuels. So far, it is mainly produced through petrochemical routes. Alternative production routes, for example through biorefinery, are under investigation but are currently not at a market competitive level. Possible alternatives, such as acetone-butanol-ethanol (ABE) fermentation by solventogenic clostridia are not market-ready to this day either, because of their low butanol titer and the high costs of feedstocks. Here, we analyzed wheat middlings and wheat red dog, two wheat milling byproducts available in large quantities, as substrates for clostridial ABE fermentation. We could identify ten strains that exhibited good butanol yields on wheat red dog. Two of the best ABE producing strains, Clostridium beijerinckii NCIMB 8052 and Clostridium diolis DSM 15410, were used to optimize a laboratory-scale fermentation process. In addition, enzymatic pretreatment of both milling byproducts significantly enhanced ABE production rates of the strains C. beijerinckii NCIMB 8052 and C. diolis DSM 15410. Finally, a profitability analysis was performed for small- to mid-scale ABE fermentation plants that utilize enzymatically pretreated wheat red dog as substrate. The estimations show that such a plant could be commercially successful. Key points • Wheat milling byproducts are suitable substrates for clostridial ABE fermentation. • Enzymatic pretreatment of wheat red dog and middlings increases ABE yield. • ABE fermentation plants using wheat red dog as substrate are economically viable.

The purpose of the study was to recover butanol from the effluent of the hydrogen-producing bioreactor containing acetate, butyrate, and carbohydrate. The butanol production by Clostridium beijerinckii NRRL B592 was evaluated under both unsterilized and sterilized conditions for examining the potential of butanol production for the practical application. Sucrose of 10 g/L and butyrate of 2 g/L coupled with acetate buffer were used to mimic the effluent. Sucrose was completely consumed in the both unsterilized and sterilized conditions during acetone-butanol-ethanol (ABE) fermentation. However, the results illustrate that the carbohydrate consumption rate in the unsterilized condition was higher than that in the sterilized condition. The maximum butanol concentrations of 3,500 and 3,750 mg/L were achieved in the sterilized and unsterilized conditions, respectively. Meanwhile, it was found that the acetate and the butyrate concentrations of 600 and 1,500 mg/L, and 300 and 1,000 mg/L were ingested to yield butanol in the sterilized condition and in the unsterilized condition, respectively. The results concluded that high levels of acetate and butyrate could eliminate the interference of other microbial populations, resulting in the enrichment of C. beijerinckii NRRL B592 in the fermentor. The butanol production by C. beijerinckii NRRL B592 could be, therefore, produced from the effluent of the hydrogen-producing bioreactor. It promised that the microbial butanol production is one of attractive bioprocesses to recover energy from wastes.
