“…It has been used mainly in intensive systems with high-fertility soils (Valle et al, 2009). Moreover, this forage has a high biomass potential and is promising as a biofuel feedstock (Odorico et al, 2018). The polyploidy and domestication process of this forage grass ensure high genetic variability to be explored (Jank et al, 2011); however, a lack of knowledge of the biology and genetics of the species, including its autotetraploidy and facultative apomictic mode of reproduction (Warmke, 1954), may make breeding more difficult and thus stimulate a need to invest in genetic studies.…”

“…10,11 Surprisingly, little attention has been devoted to the utilization of DESs in manufacturing natural fibers. Since ILs are capable of manufacturing natural fibers, some have reported that DESs could also dissolve gummy matter such as lignin and hemicellulose, [12][13][14] thus it is hypothesized that DESs can be utilized in the manufacture of natural fibers. To explore this hypothesis, the most common DES, which is composed of chloride and carbamide, was applied to ramie.…”

Ramie is one of the most important fiber resources and it needs the degumming process to produce fibers. The traditional manufacturing process of ramie fibers requires a large amount of alkali, which causes serious environmental issues. This paper provides a novel path to manufacture ramie fibers without alkali. In this study, ramie bast was pretreated by steam explosion and then treated with deep eutectic solvent. The properties of ramie fibers prepared by the novel alkali-free method, including physical properties, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD), were compared with that produced by the traditional alkali process. Results showed that the fiber qualities, including residual gum content (4.68%), average fiber fineness (1419.99 Nm) and breaking tenacity (5.98 cN/dtex), were comparable with the traditional alkali process, which all meet the requirement of the relevant Chinese National Standards. The FTIR, SEM and XRD results all confirmed the degumming ability of the novel method to manufacture ramie fibers. Moreover, the novel method was proved to be eco-friendly. Taken together, these data indicate that the novel alkali-free method is green and effective in manufacturing ramie fibers.

“…Based on these results, temperature has a critical effect on the dissolution of biomass, which could be attributed to the reduced recalcitrance of biomass at high temperatures and higher energy input 49 . Parallel findings are demonstrated for biomass pretreatment using different ILs and other pretreatment technologies, which showed enhancement of biomass fractionation upon a rise in the temperature through the course of pretreatment 20 , 50 , 51 .…”

Application of cost-effective pretreatment of wheat straw is an important stage for massive bioethanol production. A new approach is aimed to enhance the pretreatment of wheat straw by using low-cost ionic liquid [TEA][HSO4] coupled with ultrasound irradiation. The pretreatment was conducted both at room temperature and at 130 °C with a high biomass loading rate of 20% and 20% wt water assisted by ultrasound at 100 W-24 kHz for 15 and 30 min. Wheat straw pretreated at 130 °C for 15 and 30 min had high delignification rates of 67.8% and 74.9%, respectively, and hemicellulose removal rates of 47.0% and 52.2%. Moreover, this pretreatment resulted in producing total reducing sugars of 24.5 and 32.1 mg/mL in enzymatic saccharification, respectively, which corresponds to saccharification yields of 67.7% and 79.8% with commercial cellulase enzyme CelluMax for 72 h. The ethanol generation rates of 38.9 and 42.0 g/L were attained for pretreated samples for 15 and 30 min, equivalent to the yields of 76.1% and 82.2% of the maximum theoretical yield following 48 h of fermentation. This demonstration provided a cheap and promising pretreatment technology in terms of efficiency and shortening the pretreatment time based on applying low-cost ionic liquid and efficient ultrasound pretreatment techniques, which facilitated the feasibility of this approach and could further develop the future of biorefinery.
