Vertical tubular photobioreactors are made up of transparent vertical tubing to allow light penetration (Richmond, 2004). The bottom of the reactor is attached with a sparger to convert the sparged gas into tiny bubbles. This enables mixing and mass transfer of CO2 and removes the O2 produced during photosynthesis. Based on the mode of flow, these vertical tubular photobioreactors can be classified as bubble column and airlift reactors (Ramanathan et al., 2011). Ramanathan and his co-workers (2011) cultivated marine microalgae, that is, Nanochloropsis occulata and Chaetoceros calcitrans, in tubular photobioreactors. The study resulted in higher biomass productivity due to the large illuminating surface area of the photobioreactor.
