Problems of design and ecological considerations in mass culture of algae

Abstract

Abstract A 2000 l. 1 m. deep mass culture of algae was operated with continuous stirring, as an open system. The system behaved as an ecological unit selecting the most favored species. The ecological conditions could be modified by stirring speed and pattern in the tank. Methods for improving yields and utilization of CO 2 are described. Assessment of algal species for suitability in mass cultures is discussed. Yields obtained were 13 g. dry matter/sq. m. illuminated area/day.
