Abstract
    Seawater diluted with secondary-treated sewage effluent provides excellent enrichment for the maintenance of mixed natural populations of marine phytoplankton in continuous culture. Treated effluent, sampled over 1 yr, was consistent in the ratios of plant nutrients and similar in its properties of plant growth stimulation and level of toxicity. The heterogeneous continuous culture system produced large quantities of plant carbon with the concomitant removal of nitrogen and phosphorus from sewage effluent. The plant spp that grew in the continuous cultures were common to the typical coastal phytoplankton and the selection and elimination of spp was gradual considering the chemical complexity of the sewage effluent enrichment.
