Chemistry of the Nucleic Acids of Microorganisms

DNA Base Composition and Taxonomy of Some Micrococci

“…As regards the species within the genus Micrococcus and their DNA base compositions, data on only some of the species can be found in the literature (Belozersky & Spirin, 1960;Marmur, Falkow & Mandel, 1963). With the exception of reports by Silvestri & Hill (1965), Auletta & Kennedy (1966) and Rosypalova, BohaEek & Rosypal (1966), the yo GC contents of DNA have not directly been used in the classification of the genus Micrococcus.…”

Deoxyribonucleic acid of cotton

“…The deoxyribonucleic acid (DNA) composition of microorganisms has been studied extensively and the vast data obtained form the basis for the concept of chemical specificity of nucleic acids in general (1). In contrast, the DNA composition of higher plants has received relatively little attention (11,14,15,16).…”

LYTIC ACTION OF CHLORPROMAZINE HYDROCHLORIDE ON ESCHERICHIA COLI G. CELLS

“…Our observations also indicate an age-dependent action of the compound on a micro-organism. The lag period in the bacterial culture is mainly the period of profuse synthesis of deoxyribonucleic acid (Belozersky, 1959) and only during this period has the cell wall been found to be highly vulnerable to chlorpromazine. Moreover, we have observed that the compound produces a considerable decrease in the surface tension of the medium.…”
