PART I: Groups definition from the FCM point of view

I agree I do not agree
Q: Based on litterature from 1983 to 2017, do you agree on
these group definitions:
Prochlorococcus, Synechococcus, Eukaryotes Picophytoplankton, Eukaryote
Nanophytoplankton, Cryptophytes, Coccolithophores, Microphytoplankton and
Heterotrophic Bacteria
![Page 19: The setting up of new flow cytometry standardized and ... › content › download › 2192 › ... · Soumaya LAHBIB email: soumaya.lahbib@mio.osupytheas.fr Third JERICO-NEXT Workshop](https://reader033.vdocuments.us/reader033/viewer/2022060406/5f0f87a97e708231d4449e59/html5/thumbnails/19.jpg)
* Prochlorococcus
Prochlorococcus are defined as the smallest cyanobacteria found in marine environment. No staining is
required to distinguish them by flow cytometry. FWS and FLR signatures are the smallest recorded up
to now and require sensitive PMT or high powered lasers. The cluster, when well defined (often deep
water communities) is below or may overlap that of Synechococcus group, and is often partially masked
by the instrument background noise.
In samples stained for Heterotrophic bacteria analysis, Prochlorococcus can be distinguished using
Sideward Scatter (SWS) vs Chlorophyll Red Fluorescences (FLR) cytogram. They do not emit orange
fluorescence because they lack phycoerythrin.
* Prochlorococcus
Prochlorococcus are defined as the smallest cyanobacteria found in marine environment. No staining is
required to distinguish them by flow cytometry. FWS and FLR signatures are the smallest recorded for
any photosynthetic organisms up to now and require sensitive PMT or high powered lasers. The cluster,
when well defined (often deep water communities) is below or may overlap that
of Synechococcus group, and is NOT masked by the instrument background noise. When the cluster is
not well defined, that is when it is partially masked by the noise.
In samples stained for Heterotrophic bacteria analysis, Prochlorococcus can be distinguished,
particularly deep communities (but not surface communities), using Sideward Scatter (SWS) vs
Chlorophyll Red Fluorescences (FLR) cytogram. They do not emit orange fluorescence because they lack
phycoerythrin.
NOTE: often the background noise is mostly NOT due to the instrument. It is due to heterotrophic
bacteria, if the instrument is a good one.
SuggestionI agree (90%)
I do not agree (10%)

Conclusion
• Whatever the instrument usedCommon Vocabulary (CV)
• We created 44 FCM CV European portals
• Decide on a group of experts interested in contributing to thevocabulary work and decide on a co-ordinator
• Update is possible/The BODC Vocabulary Editor webpage:https://www.bodc.ac.uk/resources/vocabularies/vocabulary_editor/
• BODC is setting up some repositories on GitHub for each individualcollection and F02 will have its own too. So this could be used to shareand discuss issues more widely.
• Valuable information are gathered from the questionnaire
• Set up a Quality control protocol for FCM data (70% no flag)
“Needs for standardisation , Needs for automated clustering ”
