    摘要： An upflow bioreactor includes a vessel having an inlet and an outlet configured for upflow operation. A septum is positioned within the vessel and defines a lower chamber and an upper chamber. The septum includes an aperture that provides fluid communication between the upper chamber and lower chamber. The bioreactor also includes means for releasing pressure buildup in the lower chamber. In one configuration, the septum includes a releasable portion having an open position and a closed position. The releasable portion is configured to move to the open position in response to pressure buildup in the lower chamber. In the open position fluid communication between the lower chamber and the upper chamber is increased. Alternatively the lower chamber can include a pressure release line that is selectively actuated by pressure buildup. The pressure release mechanism can prevent the bioreactor from plugging and/or prevent catastrophic damage to the bioreactor caused by high pressures.

    摘要： The present invention is a system for harvesting algae in continuous fermentation. There is a harvester including a main moving belt, a plurality of rollers, and a motor for driving the main motor belt. There is a reactor tank and a vacuum extractor for applying a vacuum over a width of the main moving belt to extract biomass and to dry the main moving belt. The main moving belt has one end in the reactor tanks and another end extended into the vacuum extractor. The algae contained in the reactor tank is collected for further processing, including oil extraction. With algae harvested in the large-scale manner of the present invention, a more efficient oil extraction method can be used because of the concentration, temperature, and pressure can be more easily controlled.
