It was shown that actinomycete was a new natural variant that was named Streptoverticillium alboreticuli var.
[Characteristics of a new aromatic heptaenic antibiotic, flavumycin A].
: The study of the products of alkaline and acid hydrolysis showed that flavumycin A included mycosamine, an aminosugar and n-aminoacetophen, an aromatic fragment. The main functional groups of the…
[Actinomyces chromogenes var. graecus var. nov., a producer of a new hexaene antibiotic].
The actinomycete LIA-O832 was isolated from a soil sample of Greece and produced an antibiotic complex including 4 antibiotics, i.e. a tetraen antibiotic primaricin, a new hexaen named grecomycim and 2 non-polyenic antibiotics, one of which was close to kikumycin and the other wasclose to aksenomycin.
