Various pretreatments on Ceiba pentandra (L.) Gaertn. (kapok) fiber prior to enzymatic hydrolysis for sugar production were optimized in this study. The optimum conditions for water, acid, and alkaline pretreatments were 170°C for 45 min, 120°C for 45 min in 1.0% (v/v) H2SO4 solution and 120°C for 60 min in 2.0% (v/v) NaOH solution, respectively. Among the three pretreatments, the alkaline pretreatment achieved the highest total glucose yield (glucose yield calculated based on the untreated fiber) (38.5%), followed by the water (35.0%) and acid (32.8%) pretreatments. As a result, the relative effectiveness of the pretreatment methods for kapok fiber was verified as alkali>water>acid at the condition stated.
本研究对预处理剑麻(Ceiba pentandra(L.)Gaertn.)纤维以提高酶解生产糖的效率进行了优化。水、酸和碱预处理的最佳条件分别为 170°C 下 45 分钟、1.0%(v/v)H2SO4 溶液中 120°C 下 45 分钟和 2.0%(v/v)NaOH 溶液中 120°C 下 60 分钟。在这三种预处理方法中,碱预处理的总葡萄糖产率(基于未处理纤维计算的葡萄糖产率)最高(38.5%),其次是水(35.0%)和酸(32.8%)预处理。因此,在所述条件下,剑麻纤维预处理方法的相对有效性为碱>水>酸。
