The Taxonomy of Pseudanabaena （Cyanobacteria） and Characters for Judging the Production of Odor Compounds

Abstract

Two methods had been proposed for judging the production of 2－MIB for the genus Pseudanabaena. One uses cell size （width and length/width ratio） and the other uses the pigments （color of cells） and/or judges by use of fluorescence microscopy. We evaluated both methods using Pseudanabaena strains from Japanese waterbodies. As a result, both methods were not supported.
