“…The use of sodium hydroxide as a catalyst during ethanol organosolv pretreatment could greatly improve the delignifying ability of ethanol, resulting in the increase of enzymatic digestibility (Marton & Granzow, ). Tang, Chen et al () performed the ethanol organosolv pretreatment of cornstalks using sodium hydroxide as a base catalyst. After optimizing the process conditions, a high delignification degree (>80%) was obtained with minimal hemicellulose degradation at 110°C, 90 min, 4 wt% sodium hydroxide, and 60 v% ethanol.…”

Lignocellulosic biomass is one of the potential feedstocks to produce second-generation cellulosic ethanol and biochemicals. To enhance the enzymatic digestibility of lignocellulosic biomass for efficient enzymatic saccharification, a variety of pretreatment methods have been studied. Among these, organosolv pretreatment using ethanol is a promising pretreatment method owing to its inherent advantages, such as low solvent cost, lack of toxicity, the ability to retain most cellulose fraction in substrates for enzymatic hydrolysis, coproduction of high-purity lignin and hemicellulosic sugars, easy solvent recovery, and reuse. In this review, the research progress regarding different types of ethanol organosolv pretreatment processes has been summarized in terms of methods, substrate properties, reaction mechanisms, delignification kinetic as well as the impact of pretreatment methods on the enzymatic digestibility. Attempts are also made to provide insights into the complete utilization of lignocellulosic biomass to achieve high potential revenues. Though some ethanol organosolv processes have been studied or are being developed towards commercialization, ethanol organosolv pretreatment is still facing some challenges. Finally, the direction for future work is given to develop a proper ethanol organosolv pretreatment for commercialization.

“…In addition, polymeric resins potentiate the reduction of the overall production cost due to their reusability without affecting the process efficiency and in some cases without altering the sugar concentration contained in the hydrolysate (Gao and Rehmann, 2016). Previous studies on biobutanol production from corn stover have tried to solve each one of the abovementioned parameters through the selection of mutant and wild type solventogenic Clostridium strains (Liu et al, 2017;Qureshi et al, 2010;Tang et al, 2017;Wang and Chen, 2011;Xue et al, 2016a;Zhang et al, 2018); the use of different pretreatment reagents and conditions (Baral and Shah, 2017;Tang et al, 2017;Xue et al, 2016a;Zhang et al, 2014) and hydrolysate detoxification by various methods (Liu et al, 2017;Qureshi et al, 2010;Tang et al, 2017;Wang and Chen, 2011;Xue et al, 2016a;Zhang et al, 2018). Currently, studies conducted to potentiate biobutanol industrial production from corn stover are clearly required to increase yield values, but also to reduce the associated economic costs.…”

“…According to these results and taking into account both ABE concentrations and sugar consumption, it was decided to select the strain DSM 13864 for the optimisation experiments. Corn stover hydrolysates have been subjected to ABE fermentation employing several wild strains, such as C. acetobutylicum P262(Parekh et al, 1988), C. acetobutylicum zzu-02(Zhang et al, 2018), C. acetobutylicum ATCC 824 (=DSM 792)(Wang and Chen, 2011;Zhang et al, 2014), C. beijerinckii NCIMB 8052 (=CECT 508)(Liu et al, 2017), C. beijerinckii zzu-01(Zhang et al, 2018), C. beijerinckii P260(Qureshi et al, 2010;Qureshi et al, 2014) and C. saccharobutylicum DSM 13864(Xu et al, 2016); or modified strains, like C. acetobutylicumABE-P 1201 (Cai et al, 2017, C. beijerinckii CC101(Xue et al, 2016a) or C. beijerinckii NCIMB 4110(Tang et al, 2017).

A global approach to obtain biobutanol from corn stover

Corn stover was subjected to a complete biorefinery process at laboratory-scale in order to obtain biobutanol. The focus was placed on process simplification, reduction of reagents and optimisation of acetone-butanol-ethanol (ABE) fermentation. The main recommendations include the use of lower acid concentrations during the physicochemical pretreatment, the selection of adequate Clostridium strains, detoxification of the hydrolysates with reusable adsorption resins and the possibility of performing gas stripping offline to recover ABE solvents. Various pretreatment conditions, fifteen bacterial strains and three polymeric adsorption resins were assessed. The proposed method consisted of a physicochemical pretreatment with 0.89% H2SO4 (w/w) at 160 °C during 5 min, followed by an enzymatic hydrolysis, which released 75% of the sugars contained in corn stover. The hydrolysate was detoxified with the resin Dowex® Optipore ® SD-2 and fermented by C. saccharobutylicum DSM 13864, producing 4.75 ± 0.25 g/L acetone, 9.02 ± 0.11 g/L butanol and 0.39 ± 0.01 g/L ethanol in 72 h, with a sugar consumption of 97.3 ± 0.27%. A two-stage gas stripping was applied to the fermentation broth, obtaining butanol-rich condensates (418-425 g/L in the organic phase) in a total time of 6 h.

Lignocellulosic biomass is the most abundant renewable source of bioenergy. However, its intertwined structures prevent the embedded cellulose and hemicellulose from undergoing further chemical transformations. Organosolv pretreatment has been known to be effective in reducing the recalcitrance of lignocellulosic biomass. It possesses advantages in the recovery of components and the recovered components such as cellulose can be converted into bioproducts through consolidated bioprocessing (CBP). The main objective of this paper is to review recent developments in organosolv pretreatment, including a comparison of different organic solvents and their optimum operation conditions in terms of pretreatment performance and efficiency. Conventional solvents were also compared with several emerging solvents to discover more potential utilization of organosolv pretreatment. This paper also reviewed fundamental knowledge regarding organosolv pretreatment such as its mechanism, and the chemical and physical properties of the solvents, which are still rarely discussed in the literature due to a lack of conclusive information. The challenges and way forward for organosolv pretreatment were also analyzed in depth to consider the synergistic advantages after the integration of organosolv pretreatment into CBP. It is believed that, through more fundamental exploration and optimization work, organosolv pretreatment can play a vital role in determining the sustainability of CBP, to pave the way for more efficient bioprocessing in the future. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd
