以海藻为原料，研究了酸水解和酶糖化制备生物乙醇的工艺。选择红海藻（Gelidium amansii）、褐海藻（Laminaria japonica）和绿海藻（Codium fragile），对其转化为生物乙醇的特性进行了分析。海藻稀酸水解制备生物乙醇的最佳预处理条件为反应温度150℃，硫酸用量5.0 wt.%，反应时间60 mm。按生物乙醇转化性能排序的海藻依次为红海藻>褐海藻>绿海藻。酶的最佳用量为每10 g海藻2.0 mL。利用海藻生产生物乙醇的最佳发酵条件为：商品酵母用量为30wt .%，发酵时间为3天。(C) 2013韩国工业与工程化学学会。Elsevier B.V.版权所有。
The production of bioethanol from seaweeds using acid hydrolysis and the enzymatic saccharification was studied. Red seaweed (Gelidium amansii), brown seaweed (Laminaria japonica), and green seaweed (Codium fragile) were selected, and the characteristics of their conversion to bioethanol were analyzed. The optimum conditions of the dilute acid hydrolysis preprocessing for bioethanol production from the seaweed were a reaction temperature of 150 degrees C, sulfuric acid content of 5.0 wt.%, and reaction time of 60 mm. The seaweeds listed in order of bioethanol conversion performance are red seaweed > brown seaweed > green seaweed. The optimum dosage of enzyme was 2.0 mL per 10 g of seaweed. The optimal fermentation conditions for bioethanol production using seaweed included a commercial yeast dosage of 30 wt.% and a fermentation time of 3 days.
