Our phycologists have over 4 decades of experience with algal identification, and we strive to remain up to date with the continually changing field of algal taxonomy.
All identifications are made to the lowest practical level.
Potentially Toxigenic (PTOX) Cyanobacteria Screen
Don’t know what you have? Is your water green or scummy and you think it may be due to potentially toxigenic (PTOX) cyanobacteria? You can find out quickly by sending us a sample and requesting a PTOX cyanobacteria screen.
We use inverted microscopes equipped with phase contrast optics to see if your sample contains these harmful organisms. With our experience and published literature, we can tell you whether or not the cyanobacteria present are a potential threat.
We find this approach equally beneficial to us and our clients. Using algal identification prior to any toxin analysis not only helps us to learn more about potential toxin producers but helps you to save money by preventing unnecessary analyses/testing.
The PTOX cyanobacteria screen can be completed within hours of receiving the sample (typical turnaround time is less than 1 day from receipt).
When a quantitative analysis of the algal community in a sample is required, an algal identification and enumeration can be requested. Counts can be performed on only a single group of algae (i.e. cyanobacteria) or on the entire algal population.
Results for each species are recorded in natural units/mL (cells, colonies, filaments) and cells/mL. Numbers for each group of algae (i.e. diatoms, green algae, cyanobacteria) are tallied as well as the total sample cell density. If desired, biovolume estimates can be made for an additional cost.
GreenWater Laboratories now offers private algal taxonomy workshops, to be held on site at GreenWater Laboratories in Palatka (groups under 4) or in your own facilities.
Andrew Chapman is a skilled phycologist and has been conducting workshops for over 10 years. Workshops typically take place over 1-3 days.
