Direct biodiesel production from wet fungal biomass may significantly reduce production costs, but there is a lack of fast and cost-effective processing technology. A novel thin film continuous flow process has been applied to study the effects of its operational parameters on fatty acid (FA) extraction and FA to fatty acid methyl ester (FAME) conversion efficiencies. Single factor experiments evaluated the effects of catalyst concentration and water content of biomass, while factorial experimental designs determined the interactions between catalyst concentration and biomass to methanol ratio, flow rate, and rotational speed. Direct transesterification (DT) of wet Mucor plumbeus biomass at ambient temperature and pressure achieved a FA to FAME conversion efficiency of >90% using 3 wt/v % NaOH concentration, if the water content was ≤50% (w/w). In comparison to existing DT methods, this continuous flow processing technology has an estimated 90-94% reduction in energy consumption, showing promise for up-scaling.
从湿真菌生物质直接生产生物柴油可以显著降低生产成本，但缺乏快速且经济高效的加工技术。一种新颖的薄膜连续流动工艺已被应用于研究其操作参数对脂肪酸（FA）提取和 FA 到脂肪酸甲酯（FAME）转化效率的影响。单因素实验评估了催化剂浓度和生物质含水量的影响，而析因实验设计则确定了催化剂浓度与生物质与甲醇比、流速和转速之间的相互作用。在环境温度和压力下，直接酯交换（DT）湿毛霉生物质在 3wt/v%NaOH 浓度下，如果水含量≤50%（w/w），则 FA 到 FAME 的转化率超过 90%。与现有的 DT 方法相比，这种连续流动处理技术的能耗估计降低了 90-94%，具有扩大规模的潜力。
