Prochlorococcus sp., the smallest and the most abundant photoautotroph in the oceans can be very dim in surface layers, which makes it quite hard to detect by many flow cytometers. Due to its key role in a variety of ecosystems, particularly in oligotrophic ones, we optimised our CytoSense in order to be able to fully resolve it from noise and other cells/particles. We are happy to announce the very first research article where Prochlorococcus sp. was analysed by CytoSense. The importance of such application is tremendous, as stated by the first author Pierre Marrec in his paper (Coupling physics and biogeochemistry thanks to high-resolution observations of the phytoplankton community structure in the northwestern Mediterranean Sea, Biogeosciences, 15,1579-1606,2018):

'The unprecedented spatial and temporal resolution obtained thanks to the latest advances in CytoSense automated flow cytometer's deployment allowed us to clearly demonstrate the preponderant role of physical fine-scale processes in the phytoplankton community structure distribution.'
