PG - 16-9 LID - S0167-7012(16)30008-2 [pii] LID - 10.1016/j.mimet.2016.01.006 [doi] AB - Cyanobacteria contain pigments, which generate auto-fluorescence that interferes with fluorescence in situ hybridization (FISH) imaging of cyanobacteria. We describe simple chemical treatments using CuSO4 or H2O2 that significantly reduce the auto-fluorescence of Microcystis strains. These protocols were successfully applied in FISH experiments using 16S rRNA specific probes and filamentous cyanobacteria. CI - Copyright (c) 2016 Elsevier B.V. All rights reserved.
