| Definition | The OraPicoProk, often identified as Synechococcus cells, are unicellular photosynthetic cyanobacteria with forward scatter and sideward scatter signatures larger than those of most of marine heterotrophic bacteria. Their optical signatures can span over almost two decades of signal sensitivity range (Vaulot et al., 1995). Staining is not required to distinguish them by flow cytometry due to the presence of photosynthetic pigments. When excited by a blue laser, the OraPicoProk cluster displays higher forward scatter and red fluorescence signatures than RedPicoProk at any given depth. They contain phycoerythrin, and have a distinct orange fluorescence signature which can be excited by any <575 nm wavelength laser. Depending on the band pass filters, the OraPicoProk cluster is well resolved in red vs green, and/or in red vs orange fluorescence cytograms when containing phycoerythrin. | |
