Table 3.
Microcystin degradation rates under different media with variable total organic carbon and total nitrogen concentrations. Ratios correspond to assay period until 90% of total MCs degradation was achieved. (+) and (−) mean presence and absence of mlr genes, respectively. Errors represent standard errors of two replicates.
