温室气体排放的增加和化石燃料供应的减少凸显了对环境可持续能源的需求。木质纤维素，通常简称为植物生物质，是最丰富的生物燃料可再生资源之一。来自森林残留物、农业废弃物和能源草的木质纤维素生物质被广泛用于生物能源生产。这种可再生生物质资源丰富，易于获取，相对便宜，并且使能源矩阵多样化（Marriott et al., 2016）。禾草木质纤维素材料主要由次生细胞壁组成，主要由纤维素（25%-55%）、半纤维素木聚糖（20%-50%）、木质素（10%-35%）和少量果胶组成，这取决于植物种类、器官、细胞类型和组织发育阶段。尽管果胶是一种次要的细胞壁成分，但越来越多的证据表明果胶多糖参与了细胞壁的抵抗（Biswal et al., 2018）。
BackgroundIncreasing greenhouse gas emissions and diminishing supplies of fossil‐derived fuels underline the need for environmentally sustainable energy resources. Lignocellulose, more generically named simply as plant biomass, represents one of the most abundant renewable resources for biofuels. Lignocellulosic biomass from forest residues, agro‐wastes and energy grasses is extensively exploited for bioenergy production. This renewable biomass source is abundant, highly accessible, relatively cheap and diversifies the energy matrix (Marriott et al., 2016). Grass lignocellulosic material consists mostly of secondary cell walls and is composed mainly of cellulose (25%–55%), hemicellulose xylan (20%–50%), lignin (10%–35%) and small amount of pectin, depending on plant species, organ, cell types and developmental stage of the tissue. Although pectin is a minor cell wall component, there is increasing evidence suggesting that pectic polysaccharides are involved in cell wall recalcitrance (Biswal et al., 2018).
