Experimental results on the effect of Acid and Neutral Iodine on phytoplankton sample preservation expressed as cell counts, undertaken in 2013 - 2014

notPlanned

Samples consisted of 5 cultured species Ditylum brightwellii, Prorocentrum lima, Karenia mikimotoi, Coccolithus pelagicus & Tetraselmis suecica and one wild (mixed) sample. Each of the samples were diluted and divided equally between three plastic bottles which had been spiked with one of three Lugol's Iodine solutions (one neutral and two acidic). After 24 hrs a 5mL subsample from each bottle was settled into a 5mL Utermöhl chamber and all cells enumerated using an inverted microscope, after which the subsample was discarded. The process was repeated after 3 days, 1 week, 2 weeks, 1 month, 2 months, 4 months, 6 months and 8 months after preservation.
