Abstract
Assimilation of phosphate by Chlorella pyrenoidosa was 0.81–8.1 mg PO4-P/g dry weight for heterotrophic cultures and 0.81–16.1 mg/g for mixotrophic cultures. Optimal carbon:phosphorous (C/P) ratios were 206:1–2060:1 and 103:1–2060:1 for heterotrophic and mixotrophic cultivations, respectively. These requirements for phosphate for growth of C. pyrenoidosa under either heterotrophic or mixotrophic conditions are much less (6.25–62.5 or 3.12–62.5-fold at 10 g glucose/l) than its concentration in basal medium.
