Outline of Final Research Achievements

This study was carried out to search for algal strains that grow at a wide range of salinity and has toler-ance against ammonium nitrogen and to investigate an anaerobic digestion effluent as a medium for algal culturing. The results showed that at a range from 0.2‰ to 30.6‰ salinity did not affect the maximum growth and lipid productivity of strains A and C. The strains A and C grew at a range from 0.9 mM to 57.6 mM of ammonium nitrogen concentration. Although the maximum growth of strains A and C at this concentration was higher than that cultured in the normal f/2 medium, nitrate nitrogen was preferable for the strains A and C than ammonium nitrogen. The strains A and C grew and produced lipid in the anaerobic digestion effluent diluted with the secondarily treated sewage or seawater. As a dilution media for the anaerobic digestion effluent, the secondarily treated sewage was better than sea water.
