The extraction yield of lipids from nonbroken Neochloris oleoabundans was maximized by using multiple extraction stages and using stressed algae. Experimental parameters that affect the extraction were investigated. The study showed that with wet algae (at least) 18 h extraction time was required for maximum yield at room temperature and a solvent/feed ratio of 1:1 (w/w). For fresh water (FW), nonstressed, nonbroken Neochloris oleoabundans, 13.1 wt % of lipid extraction yield (based on dry algae mass) was achieved, which could be improved to 61.3 wt % for FW stressed algae after four extractions, illustrating that a combination of stressing the algae and applying the solvent N-ethylbutylamine in multiple stages of extraction results in almost 5 times higher yield and is very promising for further development of energy-efficient lipid extraction technology targeting nonbroken wet microalgae.

通过以N-乙基丁胺为切换溶剂进行胁迫并采用多个萃取步骤，可最大程度地提高新绿藻藻类萃取中的脂质产量。

通过使用多个提取阶段和使用应激藻类，可以从不间断的新油菜球菌中提取最大的脂质。研究了影响提取的实验参数。研究表明，对于湿藻（至少），在室温和溶剂/进料比为1：1（w / w）的情况下，最大提取量需要18 h的提取时间。用于淡水（FW），无应力，不破碎的新油菜，获得了13.1 wt％的脂质提取产率（基于干藻的质量），经过四次提取后，FW胁迫藻可以提高到61.3 wt％，这说明了对藻进行胁迫和在溶剂中施加溶剂N-乙基丁胺的组合。多个阶段的提取将使产量提高近5倍，对于进一步开发针对不间断的湿微藻的高能效脂质提取技术非常有前途。
