在生物质能利用的发展过程中，海洋生物质能，特别是藻类生物质能，被认为是目前最有潜力转化为生物燃料的候选者之一。本研究以一株新分离的梭菌为原料，建立了用稀硫酸预处理红藻生物丁醇的方法。紧张工作。在浓度为2%硫酸、温度为131℃、处理时间为20 Min的最佳条件下，生物质的最大水解率可达80.95%，生物质水解产物发酵后的生物丁醇产量为3.46 g/L，产率为0.20 g/g。结果表明，与未经处理的对照相比，转化效率提高了12.5倍，这为利用丰富、低成本、富含碳水化合物的藻类生物质发展生物丁醇工业提供了一条新的、有效的途径。
Marine biomass, especially the algal biomass, is currently considered to be one of the most potential candidates for biofuels conversion during the development of biomass utilization. In this study, a diluted sulfuric acid pretreatment method was established for biobutanol from red algal biomassGelidium amansiiusing a newly isolatedClostridiumsp. strain WK. Under the optimal condition of 2% sulfuric acid treated in 20 Min at 131 °C, the maximal hydrolysis percentage of biomass can reach up to 80.95%, and the biobutanol production was obtained to be 3.46 g/L with a yield of 0.20 g/g after the fermentation of biomass hydrolysate. This result demonstrated a 12.5‐fold enhancement of conversion efficiency compared with the untreated control, which provides a new and efficient way to develop the biobutanol industry by utilizing the abundant, low cost, and carbohydrate‐rich algal biomass.
