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. Los métodos y sistemas utilizados para extraer lípidos adecuados en la producción de biocombustible a partir de un caldo de fermentación pueden incluir utilizar calor para tratar previamente el caldo de fermentación con el fin de extraer más fácilmente un producto de microorganismos oleaginosos en el caldo. Adicionalmente o alternativamente, se puede utilizar una combinación de enzimas que incluyen amilasa, 1-4 mannosidasa, y 1-3 mannosidasa, y 1-3 mannosidasa para descomponer las paredes celulares de los microorganismos oleaginosos. Se puede reciclar el agua del caldo residual y utilizar como agua de imbibición para lavar una materia prima de proceso para extraer azúcar.
