Answered by The Community. Making the world better, one answer at a time. Microaerophiles are microorganisms which are unable to grow when oxygen concentrations reach those found in air (20%) but nevertheless whose growth requires the presence of some oxygen (e.g., 2 to 10%).  Microaerophiles appear to grow best in the presence of a small amount of free oxygen.
The dinoflagellates (Greek Î´á¿Î½Î¿Ï dinos whirling and Latin flagellum whip, scourge) are a large group of flagellate protists that constitute the phylum Dinoflagellata. Most are marine plankton, but they are common in fresh water habitats as well.heir populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy).
