- Abstract
s.-g. kim, a. choi, c.-y. ahn, c.-s. park, y.-h. park and h.-m. oh. 2005.To investigate an effective harvesting method forSpirulina platensis.Eighty per cent ofS. platensiscells in the logarithmic growth phase were harvested by flotation when the cells were set in a static condition for 2 h. The optimum harvesting time was about day 6 of cultivation. The flotation activity ofS. platensiscells was enhanced by the addition of NaCl.The harvesting ofS. platensisby flotation is a cost-effective and straightforward method that can retain the algal quality. The optimum harvesting time ofS. platensiscan be predicted by the cellular protein to carbon ratio.Flotation harvesting is also applicable to other cyanobacteria with gas vesicles.
