Deoxyribonucleic Acid Base Composition of Cyanobacteria Herdman, Michael and Janvier, Monique and Waterbury, John B. and Rippka, Rosmarie and Stanier, Roger Y. and Mandel, Manley,, 111, 63-71 (1979), doi = https://doi.org/10.1099/00221287-111-1-63, publicationName = Microbiology Society, issn = 1350-0872, abstract= Summary: The DNA base compositions of 176 strains of cyanobacteria were determined by thermal denaturation or by CsCl density gradient centrifugation. A summary of all data now available for this prokaryotic group is presented and the taxonomic and evolutionary implications are discussed., language=, type=
