“…Chloroform, ethyl acetate, n -hexane, trialkylamine, trichloroethylene, cloud point extraction (CPE), and boronic acids with organic solvent have been used for olive tree pruning residue [ 118 ], sugarcane bagasse [ 131 ] corn stover [ 63 , 132 ], aspen [ 133 ], wood [ 134 ], and synthetic [ 135 ] hydrolysates. Both ethyl acetate and trialkylamine give the best results for furans and phenolics [ 63 , 118 , 132 , 133 , 134 ], trialkylamine, and trichloroethylene in the case of acids [ 63 , 132 , 134 ]. Wilson et al [ 133 ] found that ethyl acetate extraction was more effective than roto-evaporation in removing the inhibitors.…”

The complete bioconversion of the carbohydrate fraction is of great importance for a lignocellulosic-based biorefinery. However, due to the structure of the lignocellulosic materials, and depending basically on the main parameters within the pretreatment steps, numerous byproducts are generated and they act as inhibitors in the fermentation operations. In this sense, the impact of inhibitory compounds derived from lignocellulosic materials is one of the major challenges for a sustainable biomass-to-biofuel and -bioproduct industry. In order to minimise the negative effects of these compounds, numerous methodologies have been tested including physical, chemical, and biological processes. The main physical and chemical treatments have been studied in this work in relation to the lignocellulosic material and the inhibitor in order to point out the best mechanisms for fermenting purposes. In addition, special attention has been made in the case of lignocellulosic hydrolysates obtained by chemical processes with SO2, due to the complex matrix of these materials and the increase in these methodologies in future biorefinery markets. Recommendations of different detoxification methods have been given.

“…Commonly used techniques for the removal of fermentation inhibitors include solvent extraction (Zhu et al, 2014), membrane filtration (Cao and Xu, 2019), ion exchange (Kumar et al, 2018), and adsorption (Dai et al, 2020). In comparison to other separation processes, adsorption is preferred due to its low cost and high removal efficiency.…”

“…Vacuum evaporation is used to remove the amounts of inhibitors that are associated with volatile compounds, while nonvolatile fraction is still present . Although liquid–liquid extraction is widely implemented in the field of detoxification of lignocellulosic hydrolysate, the most prominent shortcoming is that the extraction process requires an army of organic solvents, which increases the cost of separation and generates secondary pollution . Application of membranes for removal of inhibitor compounds from actual biomass hydrolysate is an efficient process.…”

BACKGROUND A series of monoacrylate modified adsorption resins from reactive mixtures with different amounts and types of monoacrylate have been synthesized by an oil/water (O/W) suspension polymerization technique and utilized to remove fermentation inhibitors and pigments from rice straw hydrolysate for the first time. The modified resin was characterized by Fourier transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM) and N2 adsorption–desorption isotherms. Batch experiments were carried out to determine the adsorption performance of the modified resin for fermentation inhibitors. Regeneration and reusability experiments were performed to evaluate the economic value. RESULTS The modified resin with 80% glycidyl methacrylate (GMA) feed and epoxy group showed optimal selectivity of fermentation inhibitors from rice straw hydrolysate. The adsorption capacities of acid soluble lignin (ASL), formic acid, acetic acid, levulinic acid, 5‐hydroxymethylfurfural (5‐HMF) and furfural onto 80% GMA modified resin were enhanced by 45%, 156%, 86%, 79%, 131%, 52%, respectively. Furthermore, the decolorization rate was improved by 12% over unmodified styrene‐divinylbenzene (St‐DVB) adsorption resin with approximately 5% sugar loss. CONCLUSION This work not only provides a potential adsorbent for the removal of fermentation inhibitors from rice straw hydrolysate, but also provides guidance for choosing and modifying the adsorbent to detoxify lignocellulose hydrolysate. © 2018 Society of Chemical Industry
