Helical-Track Bioreactors for Bacterial, Mammalian and Insect Cell Cultures

We investigated the cultivation of bacterial, mammalian and insect cells in an orbitally-shaken 250-mL disposable tube that incorporates a helical track (HT) on its inside wall. The mass transfer coefficient of oxygen (kLa) was 200%–400% higher in the HT tube than in a shake flask. Bacterial growth and plasmid production were 30% higher in the HT tube than in a 1-L Erlenmeyer flask. Mammalian cell cultures achieved a 25% higher cell density in the HT tube as compared to a 250-mL square-shaped bottle while insect cells grew as well in HT tubes as in 250-mL shake flasks. Because of their performance, disposability, and compact size, we conclude that 250-mL HT tubes are a useful alternative to other shaken containers for the cultivation of bacterial, mammalian and insect cells.
