Abstract:

The alga, Chlorella pyrenoidosa 71105, was grown as a continuously diluted culture in a 12-liter, engineering research photosynthetic gas exchanger. In this device, the algal culture surrounded a cylindrical light source having a surface area of 0.1 sq. m. Environmental conditions were kept constant by automatic control. Optimal conditions for algal growth in the gas exchanger were determined experimentally to be 35,000 foot candles, 2.5 CO2, 0.2 packed cell volume, 0.114 hr to the minus one power dilution factor, and 39 C. Under these conditions, maximum algae yield was 0.754 gmhr dry wt and maximum oxygen production was 1.25 gmhr, or 0.03 kg per day. Author
