Up to 90% of Dunaliella salina biomass remains unused after extraction of the main product β-carotene. The potential of mild hydrothermal liquefaction (HTL) to exploit this biomass as a source of valuable by-products was assessed. The results indicate that 80% of the remnant was converted into glucose by mild HTL (100°C, 0min). The recovered glucose was successfully used as a carbon source to cultivate biotechnologically relevant microorganisms, namely Chlorella vulgaris, Escherichia coli and Saccharomyces cerevisiae. Furthermore, the analysis of energy demand and operating costs confirms the beneficial effect of mild liquefaction on the overall process economics of algal β-carotene production.
杜氏盐藻在提取主要产物β-胡萝卜素后，高达 90%的生物质仍未得到利用。评估温和水热液化 (HTL) 将这种生物质作为有价值副产品来源的潜力。结果表明，温和 HTL（100°C，0 分钟）可将 80%的残余物转化为葡萄糖。回收的葡萄糖成功地用作碳源来培养生物技术相关的微生物，即普通小球藻、大肠杆菌和酿酒酵母。此外，对能源需求和运营成本的分析证实了温和液化对藻类 β-胡萝卜素生产整体工艺经济性的有益影响。
