Methods and systems used to extract lipids suitable in production of biofuels from a fermentation broth may include using heat to pre-treat the fermentation broth in order to more easily extract a product from oleaginous microorganisms in the broth. Additionally or alternatively, a combination of enzymes including amylase, 1-4 mannosidase, and 1-3 mannosidase may be used to break down cell walls of the oleaginous microorganisms. Residual broth water may be recycled and used as imbibition water for washing a process feedstock to extract sugar. 用于从发酵培养液提取适于生产生物燃料的脂质的方法和系统可以包括加热以预处理发酵培养液从而易于从培养液中的含油微生物提取产物。此外或可替换地，可以用包含淀粉酶、1-4甘露糖苷酶、和1-3甘露糖苷酶的酶组合来分解含油微生物的细胞壁。可回收残余的培养液水分并用作洗涤加工原料的吸入水(imbibition water)以提取糖。
