متن کاملRelatedness among species of fungi and higher plants measured by DNA hybridization and base ratios.
HYLOGENETIC relatedness among organisms is reflected in their genotypes. The many efforts to compare genotypes have included comparisons of morphology, physiology, reproduction, and more recently ( MCCARTHY and BOLTON 1963; BOLTON 1966) the hybridization of DNA from different species and genera. These studie; have provided convincing evidence that it is possible to demonstrate relatedness, as j...
متن کاملIntrageneric relationships among Micromonospora species deduced from gyrB-based phylogeny and DNA relatedness.
The phylogenetic structure of genus Micromonospora within actinomycetes was examined by analysing the gyrB sequences of 15 validly described species and four subspecies. All but one of the Micromonospora strains formed a tight cluster, as had previously been demonstrated by a 16S rDNA-based phylogenetic analysis. However, the intrageneric relationships deduced from the gyrB-based phylogeny were...
متن کاملStreptomyces stramineus sp. nov., a new species of the verticillate streptomycetes.
Strain NRRL 12292T, which produces the bleomycin-like antibiotics LL-BO1208 alpha and LL-BO1208 beta, forms umbels consisting of chains of smooth-surface ovoid spores that are borne on verticils on the serial mycelia, indicating that it is a member of the verticillate group of the genus Streptomyces formerly classified in the genus Streptoverticillium. This strain was compared morphologically a...
متن کاملThe Antimicrobial Activity of Streptomyces Species
A total of fifty-nine antibiotic microbial producers have been isolated from the soil, seven of them have shown activity against both Grampositive and Gram – negative bacteria. On the other hand, fiftytwo isolates were only active against Gram – positive bacteria. Of the 7 broad – spectrum antibiotic microbial producers, one isolate of high activity was chosen and has been involved throughout t...
