A novel ionic liquid-tolerant Fusarium oxysporum BN secreting ionic liquid-stable cellulase: Consolidated bioprocessing of pretreated lignocellulose containing residual ionic liquid

“…The inhibitory effects of ChOAc on cellulase and yeast cells were significantly lower than those of EmimOAc (Table 1), because the cholinium cation is reported to be more intrinsically biocompatible than the imidazolium cation [13,18,26,27]. On the other hand, in addition to the biocompatible IL-like ChOAc, IL-tolerant cellulase [8,28,29] and IL-tolerant fermentative microorganisms [30,31] are also effective in further reducing the number of post-pretreatment washes and the resultant wastewater of the diluted IL aqueous solution.…”

a b s t r a c tCholine acetate (ChOAc), a cholinium ionic liquid (IL), was used for biomass pretreatment; thereafter, saccharification of the pretreated biomass and glucose/xylose co-fermentation were conducted with different number of post-pretreatment washes (1-5 and 10 washes). Besides saccharification and cofermentation data, the inhibitory effect of ChOAc on the biocatalyst was compared with that of 1-ethyl-3-methylimidazolium acetate (EmimOAc). ChOAc showed less inhibitory effect on cellulase and yeast activity compared with EmimOAc. The cellulose and hemicellulose saccharification percentages of the IL-pretreated bagasse were approximately 90% and 60%, respectively, irrespective of ChOAc and EmimOAc with sufficient post-pretreatment washes. The cellulose and hemicellulose saccharification percentages after 5 washes were 82% and 59%, respectively, in the case of ChOAc and 51% and 13%, respectively, in the case of EmimOAc. The overall ethanol yields on the original bagasse basis after saccharification and co-fermentation of the IL-pretreated bagasse when washed 5 times were 54% and 22% in the case of ChOAc and EmimOAc, respectively. ChOAc-pretreated bagasse could be saccharified and co-fermented with fewer washes than EmimOAc-pretreated bagasse.

“…Xu el al. reported a novel IL‐tolerant Fusarium oxysporum BN secreting IL‐stable cellulase that produced bioethanol from lignocellosic biomass with a yield of 0.125 g ethanol per 1 g of rice straw . The strain of cellulolytic microorganisms was cultured in ten types of ILs and found that it was capable of growing in 10% w/v of IL.…”

Ionic liquids (ILs), a class of materials with unique physicochemical properties, have been used extensively in the fields of chemical engineering, biotechnology, material sciences, pharmaceutics, and many others. Because ILs are very polar by nature, they can migrate into the environment with the possibility of inclusion in the food chain and bioaccumulation in living organisms. However, the chemical natures of ILs are not quintessentially biocompatible. Therefore, the practical uses of ILs must be preceded by suitable toxicological assessments. Among different methods, the use of microorganisms to evaluate IL toxicity provides many advantages including short generation time, rapid growth, and environmental and industrial relevance. This article reviews the recent research progress on the toxicological properties of ILs toward microorganisms and highlights the computational prediction of various toxicity models.
