| Definition | The Orgpicopro, often identified as Synechococcus cells, are unicellular photosynthetic cyanobacteria with forward-scatter (FSC or FWS) and sideward scatter (SSC or SWS) 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 Orgpicopro cluster displays higher FSC and red fluorescence (FLR) signatures than Redpicopro at any given depth. They contain phycoerythrin, and have a distinct orange fluorescence (FLO) signature which can be excited by any <575 nm wavelength laser. Depending on the band pass filters, the Orgpicopro cluster is well resolved in red vs green (FLR/FLG) and/or in red vs orange fluorescences (FLR/FLO) cytograms when containing phycoerythrin. | |
