highly significantp = 0.0001
All three analyses showed highly significant interactions between PST and light ( p = 0.0001, p = 0.0002, p = 0.0009, for PST content, production, and C fraction, respectively), a significant interaction between lytic toxicity and whether the strains contained PST ( p = 0.0157 for PST content), and significant effects of lytic toxicity on growth ( p = 0.0125, p = 0.0175, for PST production and C fraction, respectively).
