  • Patent number: 8852924
    Abstract: A closed transparent photobioreactor having a dome and a staged column wherein the dome is used as a growth chamber to provide a large culture volume to land area used and a flow pattern inside the dome allows for the uniform distribution of light energy, thereby negating growth rate inhibiting ‘dark zones’. A pump delivers culture from the bottom of the column to a lower portion of the dome and drives circulation between the two components and an increase in mass in the dome results in a spillover from the top of the dome into the column. Once in the column, algaculture will be aerated at each stage before returning to the dome. The staged column also provides for semi-continuous harvest of algae through the application of froth flotation and various other separation processes.

  • Patent number: 7897390
    Abstract: The present invention provides a novel apparatus to grow cells where the cultivation chamber (1) is partially filled with liquid cultivation medium and cells. Mixing and aeration is achieved by generating intermittently one single large gas bubble (6) at the bottom of the column bioreactor, the single large bubble width representing from 50 to 99% of the tank width, preferably from 60 to 99%, more preferably 98.5%. The culture medium flows out as a film between the large bubble and the inner wall of the bioreactor. This rising bubble allows mixing and aeration of the bulk. As the design of the invention is very simple, it is possible to manufacture it with flexible plastic material and use the apparatus as a disposable system. Moreover, such a mixing/aeration principle minimizes cell damages usually due to shear stress and small bubbles and allows easy and efficient scale-up from small scale to a larger one. Such a large-scale, efficient and disposable culture system can largely reduce production costs.
