Lack of Deoxyribonucleic Acid-Deoxyribonucleic Acid Homology Between Thermoplasma acidophilum and Sulfolobus acidocaldarius Christiansen, Claus and Freundt, E. A. and Vinther, O.,, 31, 346-347 (1981), doi = https://doi.org/10.1099/00207713-31-3-346, publicationName = Microbiology Society, issn = 1466-5026, abstract= Abstract Deoxyribonucleic acids (DNAs) from the type strains of Thermoplasma acidophilum (strain 122-1B2) and Sulfolobus acidocaldarius (strain 98-3) are compared. The guanine-plus-cytosine contents of the DNAs are 45.0 and 39.9 mol%, respectively. DNA-DNA hybridization experiments show homologies slightly above the background level of 0.1% in the experiment., language=, type=
