Coastal Bermuda grass was pretreated with NaOH at concentrations from 0.5% to 3% (w/v) for a residence time from 15 to 90min at 121 degrees C. The pretreatments were evaluated based on total lignin removal and production of total reducing sugars, glucose and xylose from enzymatic hydrolysis of the pretreated biomass. Up to 86% lignin removal was observed. The optimal NaOH pretreatment conditions at 121 degrees C for total reducing sugars production as well as glucose and xylose yields are 15min and 0.75% NaOH. Under these optimal pretreatment conditions, total reducing sugars yield was about 71% of the theoretical maximum, and the overall conversion efficiencies for glucan and xylan were 90.43% and 65.11%, respectively.
将海岸百慕大草用浓度为 0.5% 至 3%（w/v）的氢氧化钠在 121°C 下预处理 15 至 90 分钟。根据总木质素去除率以及从预处理生物质的酶水解生产的总还原糖、葡萄糖和木糖来评价预处理效果。观察到高达 86%的木质素去除率。在 121°C 下，用于生产总还原糖以及葡萄糖和木糖产率的最佳氢氧化钠预处理条件是 15 分钟和 0.75%氢氧化钠。在这些最佳预处理条件下，总还原糖的产率约为理论最大值的 71%，且对葡聚糖和木聚糖的整体转化率分别为 90.43%和 65.11%。
