Abstract 

Arthrospira (Spirulina) platensis is one of the commercially important filamentous cyanobacteria. The heterotrophic cultivation of Arthrospira can be an alternative strategy for commercial mass production. In heterotrophic culture, the specific growth rate of A. platensis M9108, a glucose-resistant mutant of A. platensis PCC 9108, was 0.014 h-1 which was 1.8 higher than that of the previous report. The mutant possessed the facility to assimilate and to metabolize glucose efficiently under heterotrophic condition. However, the r-linolenic acid content of 6 Arthrospira strains was not increased in heterotrophic culture. Four Arthrospira strains out of 6 tested strains were able to utilize maltose as a carbon source under heterotrophic condition. The biomass production of these strains on maltose was similar to that on glucose. The specific growth rate of A. platensis M9108 increased with glucose concentration up to 5.0 g/L and then decreased at a glucose concentration of 10.0 g/L. Additionally, A. platensis M9108 under heterotrophic condition showed no aggregation during the cultivation in contrast to A. platensis PCC 9108.
