Abstract
The DNA base composition of five recently isolated Haliscomenobacter hydrossis strains were compared with those of Sphaerotilus natans, Leptothrix cholodnii and Leptothrix discophora. The DNA base composition of H. hydrossis strains ranged from 48.3 to 49.7% GC, whereas the % GC values of S. natans, L. cholodnii and L. discophora were found to be 69.7, 69.6 and 71.2, respectively. These results indicate that Haliscomenobacter species and the microorganisms of the Sphaerotilus-Leptothrix group should not be classified into the same genus, as they are genetically at best remotely related.
The reallocation of some Leptothrix species into the genus Sphaerotilus is not in contradiction with their DNA base composition.
