Effects of Metals on Streptomyces coelicolor Growth and Actinorhodin Production.
Actinorhodin production by Streptomyces coelicolor was used as a model system to study the effects of metals on growth and polyketide synthesis in a streptomycete. Numerous metals were tested in cultures grown in liquid media. Mercury and cadmium were highly toxic, and copper, nickel, and lead were less so, but all tended to inhibit both growth and antibiotic synthesis to a similar extent. Unex...
متن کاملTime-lapse microscopy of Streptomyces coelicolor growth and sporulation.
Bacteria from the genus Streptomyces are among the most complex of all prokaryotes; not only do they grow as a complex mycelium, they also differentiate to form aerial hyphae before developing further to form spore chains. This developmental heterogeneity of streptomycete microcolonies makes studying the dynamic processes that contribute to growth and development a challenging procedure. As a r...
متن کاملA pigmented mycelial antibiotic in Streptomyces coelicolor: control by a chromosomal gene cluster.
Streptomyces coelicolor was found to produce a third secondary metabolite, in addition to the antibiotics methylenomycin A and actinorhodin previously described. This is a red pigmented, highly non-polar compound with antibiotic activity against certain Gram-positive bacteria. Mutants lacking the red compound fell into five cosynthetic classes. Representatives of each of the five classes were m...
متن کاملObservations 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 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...
