Specific growth rate, colonial morphology and extracellular polysaccharides (EPS) content of Scenedesmus obliquus grown under different levels of light limitation
Relationships among cells per particle, EPS content and growth rate of Scenedesmus obliquus are investigated. Cells per particle increased from 1.2 to 2.8 when growth rate decreased from 0.65 to 0.40 day-1; but it fell back to 1.2 as growth rate decreased from 0.40 to 0.14 day-1. The increasing EPS content may not lead to colony formation of S. obliquus.
