Deoxyribonucleic Acid Base Composition and Taxonomy of Thiobacilli and some Nitrifying Bacteria

Adansonian Analysis and Deoxyribonucleic Acid Base Composition of Some Gram-negative Bacteria.

Colwell, R. R. (Georgetown University, Washington, D.C.), and M. Mandel. Adansonian analysis and deoxyribonucleic acid base composition of some gram-negative bacteria. J. Bacteriol. 87:1412-1422. 1964.-The deoxyribonucleic acid (DNA) base compositions and S values for a minimum of 134 coded properties were determined for representative cultures of the genera Pseudomonas, Xanthomonas, Aeromonas,...

Comparison of the morphology and deoxyribonucleic acid composition of 27 strains of nitrifying bacteria.

The gross morphology, fine structure, and per cent guanine plus cytosine (GC) composition of deoxyribonucleic acid of 27 strains of nitrifying bacteria were compared. Based on morphological differences, the ammonia-oxidizing bacteria were separated into four genera. Nitrosomonas species and Nitrosocystis species formed one homogenous group, and Nitrosolobus species and Nitrosospira species form...

Deoxyribonucleic acid base composition and numerical taxonomy of yeasts in the genus Trichosporon.

Deoxyribonucleic acid base composition of Pseudomonas piscicida.

The marine bacterium Pseudomonas piscicida has been characterized from a taxonometric analysis of phenotypic properties of 20 strains (Hansen, Weeks, and Colwell, J. Bacteriol. 89:752, 1965). The cultures showed a mean similarity of 80% and appeared to form a species cluster. The same cultures have now been analyzed for their deoxyribonucleic acid (DNA) base composition with the result that the...

Deoxyribonucleic Acid Base Composition of Desulfotomaculum nigrificans.

The sporeforming, dissimilatory sulfate-reducing bacteria have been reclassified by L. L. Campbell and J. R. Postgate (Bacteriol. Rev. 29:359, 1965) and placed in a new genus: Desuljbtomaculum. The thermophilic sulfate-reducing bacterium, Desulfotomaculum nigrificans (Clostridium nigrificans) was designated as the type species. In a previous study of 30 strains of nonsporulating sulfate-reducin...
