- A simple biofilm-based culture system of the unicellular green alga Pseudochoricystis ellipsoidea strain Obi was developed.
- The footprint biomass productivities achieved with this system were 8-10 g mâ2 dayâ1.
- This system requires neither irrigation nor supply of CO2-enriched air.
Cells of the unicellular green alga, “Pseudochoricystis ellipsoidea”, were uniformly spread on a cellulosic sheet or on a polytetrafluoroethylene (PTFE) membrane sheet superimposed on a cellulosic sheet at a density of 3.5-5.0 g dry weight per m2, and the sheet was adhered to an inverted V-shaped acrylic plate of 10 cm in height. Several acrylic plates were placed side by side on a tray containing liquid medium at a depth of 0.6 cm, and illuminated from above with a light intensity of 300-340 μmol mâ2 sâ1. Water and nutrients were supplied to cells by capillary action through the cellulosic sheet. Footprint biomass productivities of cells grown in atmospheric CO2 on this photobioreactor were 8-10 g mâ2 dayâ1. This cultivation system is strongly energy- and labor-saving as it does not require mixing of culture fluid, irrigation of medium, and delivery of CO2-enriched air.
