چکیده انگلیسی
We investigated growth interactions between the dinophyte Prorocentrum minimum and the bacillariophyte Skeletonema costatum using bi-algal cultures under axenic conditions. When low cell densities of P. minimum and high cell densities of S. costatum were inoculated into the same medium, growth of P. minimum was suppressed. Other inoculum combinations resulted in reduced S. costatum maximum cell densities. A mathematical model was used to simulate growth and interactions of P. minimum and S. costatum in bi-algal cultures. The model indicated that P. minimum always outcompeted S. costatum over time. Enriched filtrate from low-density P. minimum cultures significantly stimulated S. costatum growth, but enriched filtrate from high-density P. minimum cultures notably inhibited the growth of S. costatum. Growth of P. minimum was not affected by enriched filtrate from cultures of P. minimum at any density. Filtrates of P. minimum cultures were fractionated by ultrafiltration (molecular weight cutoff >3000Â Da), and retentate that included polysaccharide(s) significantly inhibited the growth of S. costatum.
