Figure 4From: A simple viability analysis for unicellular cyanobacteria using a new autofluorescence assay, automated microscopy, and ImageJChlorophyll concentration for the different samples with an decreasing number of viable cells. The Chlorophyll concentration was determined for every sample in duplicates. The graph shows the values of the two single measurements (green cross and dark green cross) as well as the mean concentration (black dot) plotted over the corresponding percentage of viable cells in the sample.Back to article page
