Salinity effects on colonial Microcystis strains from laboratory experiments

This is a data set on some morphological and physiological impacts of salinity on two isolated of Microcystis aeruginosa performed in laboratory experiments in the spring of 2022.

Two non axenic isolated colonial Microcystis aeruginosa strains (PMC1323.21 and PMC1262.20) were used for the experiments. Both strains were provided by the Paris Museum Collection (PMC).


For these experiments, colonies of both strains were grown in BG11 medium in Erlenmeyer flasks and kept in an exponentially growing phase. The batch cultures were stored in a growing chamber at 22 °C and under a light intensity of 40 μE/m2/s with a photoperiod of 14h/10h.

Purpose

Determine the impact of salinity on colonial Microcystis to see if the colonial structure is more resistant to an osmotic shock than unicellular cells.
