Evidence of the Cost of the Production of Microcystins by Microcystis aeruginosa under Differing Light and Nitrate Environmental Conditions
Figure 1
Growth curves of the WT (black circles) and MT (white circles) strains in monoculture experiments under different environmental conditions.
A OLHN (optimal light and high nitrogen concentrations), B OLLN (optimal light and low nitrogen concentrations), C LLHN (low light and high nitrogen concentrations), and D LLLN (low light and low nitrogen concentrations). Error bars represent the standard deviation (N = 3). NO3 was added (dashed line) on day 11 under OLLN conditions, and on day 26 under LLLN conditions.
