Abstract: The present invention generally relates to a novel process in which thin stillage is processed to produce algae oil and protein rich biomass as well as other energy rich byproducts. In accordance with a preferred embodiment, thin stillage is removed from an evaporator during the evaporation process to produce mid-stillage. This mid-stillage is preferably routed to a new process where it is directed to a pre-treatment centrifuge to remove suspended solids, sludge and corn oil. Thereafter, the mid-stillage is preferably cooled and then directed to a fermentation tank where the mid-stillage is subject to a batch fermentation process with algae “seed” fed from an algae inoculation system. Once the batch is harvested, the oil-rich algae/mid-stillage is then preferably heated to rupture the cells and liberate the oil.

Abstract: The present invention generally relates to the production of biofuels and, in particular, to a process for simultaneous saccharification and fermentation using a microalgae substrate. According to one aspect of the present invention, a process is provided in which the temperature and pH of a broth mixture are adjusted to slow the rate of glucose conversion and to match the glucose metabolizing rate of the microalgae.
