The spherical type bubble column bioreactor (Figure 2.8) is another modified airlift reactor with spherical shape instead of cylindrical. Ihrough the addition of small amounts of agar to the culture medium, low shear stress is achieved as well as high oxygen transfer rates. As a result, 5.6 g.L of BC were produced after 72 hours of cultivation [54,55].
