Collapsing Aged Culture of the Cyanobacterium Synechococcus elongatus Produces Compound(s) Toxic to Photosynthetic Organisms
Figure 2
Light-dependent toxic effect of conditioned medium from collapsing culture.
Viability assessment using Sytox green (A), and absorbance spectra (B) of exponentially growing cells 24 h after inoculation into fresh growth medium (FM), or into conditioned medium of a collapsing culture (CM). Exposure to CM under light resulted in bleaching of cell pigments including chlorophyll (Chl) and phycocyanin (PC).
