A temperate phage of Streptomyces azureus.

摘要: A new phage, SAt1, was isolated from soil on Streptomyces azureus ATCC 14921. This phage able to lysogenize S. azureus. The percentage of lysogenic responses ca. 10%. Electron microscopic observation showed that this belonged group B Bradley's morphological classification. molecular mass SAt1 DNA 24 megadaltons. guanine-plus-cytosine content and the density were 71% 1.724 g/cm3, respectively. cleavage map constructed with restriction endonucleases BanIII, BglII, HindIII, XbaI. Furthermore, some other characteristics investigated.
