| Abstract: | Undaria pinnatifida gametophytes were grown in 2.5 l bubble column and airlift reactor at 25 °C and light intensity of 40  mol m–2 s–1 for 6 days. With aeration at 1 l min–1, the airlift reactor yielded higher growth rate (0.12 mg DW ml–1 d–1) than a bubble column (0.08 mg DW ml–1 d–1). The advantages were related to the more homogeneous fluid dynamic characteristics of the airlift reactor. |
