“…In addition, the technology could be used for producing other side products, which could elevate the overall pretreatment economic benefits. However, some key factors could affect the efficiency of straw biomass pretreatment, for instance, the IL nature characteristics (protic or aprotic), treatment conditions (reaction temperature, reaction time, and biomass particle and loading), and different types of biomass such as softwoods and hardwoods and grasses (Halder et al, 2019; Bhatia et al, 2021 ). Therefore, a variety of ILs would be synthesized to tune their characteristics by adjusting the types of cations and anions.…”

“…However, numerous technological and economic challenges exist in the process of IL treatment of straw biomass. For example, the high-cost issue for recovery and reusability of ILs was still the main obstacle in the application of some ILs in industrialization, despite some achievements that have been obtained to design inexpensive ILs ( Bhatia et al, 2021 ). Therefore, the pretreatment of ionic liquids has limited applications.…”

“…For example, in the combination treatment of Saccharum spontaneum biomass (SSB) with tris(2-hydroxyethyl)methylammonium methylsulfate ([TMA][MeSO 4 ]) and sodium dodecylsulfate (SDS), following its enzymatic hydrolysis under consolidated bioprocess (CBP), the sugar yield was increased by 2.35-fold in comparison with the untreated one ( Vaid et al, 2021 ). Moreover, Miscanthus hybrid ( Mx 27999) was pretreated by SE coupled with ILs and single treatments for the generation of oligosaccharides, respectively ( Bhatia et al, 2021 ).…”

Straw biomass is an inexpensive, sustainable, and abundant renewable feedstock for the production of valuable chemicals and biofuels, which can surmount the main drawbacks such as greenhouse gas emission and environmental pollution, aroused from the consumption of fossil fuels. It is rich in organic content but is not sufficient for extensive applications because of its natural recalcitrance. Therefore, suitable pretreatment is a prerequisite for the efficient production of fermentable sugars by enzymatic hydrolysis. Here, we provide an overview of various pretreatment methods to effectively separate the major components such as hemicellulose, cellulose, and lignin and enhance the accessibility and susceptibility of every single component. This review outlines the diverse approaches (e.g., chemical, physical, biological, and combined treatments) for the excellent conversion of straw biomass to fermentable sugars, summarizes the benefits and drawbacks of each pretreatment method, and proposes some investigation prospects for the future pretreatments.

Arundo donax, Cortaderia selloana and Phragmites australis are high-biomass-producing perennial Poalean species that grow abundantly and spontaneously in warm temperate regions, such as in Mediterranean-type climates, like those of Southern Europe, Western United States coastal areas, or in regions of South America, South Africa and Australia. Given their vigorous and spontaneous growth, biomass from the studied grasses often accumulates excessively in unmanaged agro-forestry areas. Nonetheless, this also creates the demand and opportunity for the valorisation of these biomass sources, particularly their cell wall polymers, for biorefining applications. By contrast, a related crop, Miscanthus × giganteus, is a perennial grass that has been extensively studied for lignocellulosic biomass production, as it can grow on low-input agricultural systems in colder climates. In this study Fourier transform mid-infrared spectroscopy (FTIR), high-performance anion-exchange chromatography (HPAEC) and lignin content determinations were used for a comparative compositional characterisation of A. donax, C. selloana and P. australis harvested from the wild, in relation to a trial field-grown M. × giganteus high-yielding genotype. A high-throughput saccharification assay showed relatively high sugar release values from the wild-grown grasses, even with a 0.1M NaOH mild alkali pretreatment. In addition to this alkaline pretreatment, biomass was treated with white-rot fungi (WRF), which preferentially degrade lignin more readily than holocellulose. Three fungal species were used: Ganoderma lucidum, Pleurotus ostreatus and Trametes versicolor. Our results showed that neutral sugar contents are not significantly altered, while some lignin is lost during the pretreatments. Furthermore, sugar release upon enzymatic saccharification was enhanced, and this was dependent on the plant biomass and fungal species used in the treatment. To maximise the potential for lignocellulose valorisation, the liquid fractions from the pretreatments were analysed by high performance liquid chromatography – photodiode array detection – electrospray ionisation tandem mass spectrometry (HPLC-PDA-ESI-MSn). This study is one of the first to report on the composition of WRF-treated grass biomass, while assessing the potential relevance of breakdown products released during the treatments, beyond more traditional sugar-for-energy applications. Ultimately, we expect that our data will help promote the valorisation of unused biomass resources, create economic value, while contributing to the implementation of sustainable biorefining systems.
