A healthy cyanobacterial cell can have high levels of toxin - or taste and odour compounds - confined within its walls. For example, for Microcystis aeruginosa more than 95% of the toxin can be contained within healthy cells, whereas the number would be around 50% or less for Cylindrospermopsis raciborskii.Therefore, high cell numbers can result in high total toxin concentration.
