Switchgrass ( Panicum virgatum , L., Poaceae) with the advantages of high cellulose yield, and high growth even under low input and poor soil quality, has been identified as a promising candidate for production of low-cost biofuels, papermaking, and nanocellulose. In this study, 12 chemical pretreatments on a laboratory scale were compared for different utilization purposes of switchgrass. It was found that the pretreated switchgrass with sodium hydroxide showed considerable potential for providing mixed sugars for fermentation with 11.10% of residual lignin, 53.85% of residual cellulose, and 22.06% of residual hemicellulose. The pretreatment with 2.00% (v/v) nitric acid was the best method to remove 78.37% of hemicellulose and 39.82% of lignin under a low temperature (125 °C, 30 min), which can be used in the production of nanocellulose. Besides, a completely randomized design analysis of switchgrass pretreatments provided the alternative ethanol organosolv delignification of switchgrass for the papermaking industry with a high residual cellulose of 58.56%. Finally, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR) were carried out to confirm the changes in functional groups, crystallinity, and thermal behavior of the three materials, respectively, from the optimal pretreatments.

“…Studies show that lignocellulosic biomass of the halophyte has great potential to produce a substantial amount of butanol. A substantial yield of butanol has been obtained from switchgrass (Wang et al 2019) and Suaeda salsa biomass (Zhao et al 2011). Similarly, Recently, there is an enormous research interest to produce some other energy alternative in form of biochar, bio-oil, and syngas using lignocellulosic biomass of the various halophytes (Table 4).…”

Biofuels are gaining importance due to high crude oil prices, high energy demands, and global warming issues. According to the world energy council, the biofuel production will be tripled by 2030, with Brazil and the United States contributing to 80% of the total biofuel production. The use of first generation biofuels is connected with food insecurity and increase in food prices, while second generation biofuels used raw cellulosic mass from nonfood crops. The plant-based fuels are considered in renewable sources with easy growing practices and have lesser carbon emission as compared to fossil fuels. This

“…Acetic acid pretreatment of switch grass (3g/L, 170°C for 20 min) followed by enzymatic hydrolysis (Cellic CTec 2 Novozymes) led to production of 8.6g/L butanol by Clostridium Saccharoperbutylacetonicum N1-4. (Wang et al, 2019) Among the various treatment methods such as acid, alkali and enzymatic treatment of various lignocellulosic wastes as substrates including corn wastes, barley straw, rice bran, palm waste and wood pulp etc. the best yield was achieved with wood pulp hydrolysate obtained with acid treatment followed by enzymatic treatment.…”

In lieu of rising crude oil prices, exhaustion of petroleum feed stocks and environmental challenges, only renewable fuels have the potential to match the energy requirements of the future. Among the various renewable fuels, butanol has recently gained a lot of attention because of its advantages over other biofuels. Its microbial production by clostridia through ABE fermentation is being explored for improved yield and cost effectiveness. Using lignocellulosic wastes successfully for butanol production through ABE fermentation is a major breakthrough to deal with the future energy crisis. Genetic engineering of microbes to increase the carbon and redox balance, cell recycling, media optimization, mathematical modelling and tolerance improvement strategies are being attempted to overcome the hurdles of high production cost, by products formation leading to low yield and product toxicity. Along with genetic engineering major research is cantered on heterologous host engineering for improved butanol production and tolerance. This review highlights the recent advances in improving yield and tolerance to butanol in both Clostridial and heterologous hosts from genetic engineering and fermentation methodology aspects. Int. J. Appl. Sci. Biotechnol. Vol 7(2): 130-152
