Observations on the pigment of Streptomyces coelicolor.
Several studies have been made on the conditions which determine the formation of pigments by microorganisms (Reid, 1936), their possible practical application (Beijerinck, 1913), their role in bacterial metabolism (Birkinshaw, 1937), their correlation with some morphological or physiological variations, and their chemical structures (Brazhnikova, 1946; Friedheim and Michaelis, 1931; Tobie, 193...
متن کاملOBSERVATIONS ON THE CHROMATINIC BODIES OF Streptomyces coelicolor
Colonies of Streptomyces coelicolor growing on cellophane and impression preparations from sporing colonies were stained for chromatin by the methods of Feulgen, DeLamater (1951), and Piéchaud (1954). The chromatinic bodies of the substrate hyphae have a great variety of configurations. During the development of the spores, elongated chromatinic structures in the young aerial hyphae separate in...
متن کاملRepression in Streptomyces coelicolor
A glucose kinase (glkA) mutant of Streptomyces coelicolor A3(2) M145 was selected by the ability to grow in the presence of the nonmetabolizable glucose analog 2-deoxyglucose. In this glk4 mutant, carbon catabolite repression of glycerol kinase and agarase was relieved on several carbon sources tested, even though most of these carbon sources are not metabolized via glucose kinase. This suggest...

متن کاملReciprocal Crosses in Streptomyces Coelicolor.
interaction of two complementary growth-factor dependent mutants, i.e., Tzp lemen ta ry auxotrophs, of Streptomyces coeticolor to form grovvth-factor independent progeny, i.e., prototrophs, was interpreted as gene recombination by SERMO~TI and SPADA-SERMONTI (1955) and by BRAENDLE and SZ+BALSKI (1959yi but as heterokaryosis by BRADLEY (1957). The former workers concluded that gene recombination...
