Of 31 freshwater bacterial isolates screened using the Biolog MT2 assay to determine their metabolism of
the microcystin LR, 10 were positive. Phylogenetic analysis (16S rRNA) identified them as Arthrobacter spp.,
Brevibacterium sp., and Rhodococcus sp. This is the first report of microcystin degraders that do not belong to
the Proteobacteria.
