title: [Madumycin biosynthesis by an Actinomadure flava culture under conditions of varying aeration].
abstract: Production of madumycin I and madumycin II by 2 strains of Actinomadure flava 2171 was studied. Intensive aeration was an obligatory condition for the antibiotic biosynthesis. The content of madumycins I and II in the culture fluid depended on the strain, aeration conditions and fermentation cycle. Strain 2171/852 produced maximum amounts of madumycin I and madumycin II by the 2nd--3rd and 5th days of cultivation respectively. Strain 2171/2544 mainly produced madumycin I during the whole period of fermentation.
