title: [Formation of dextranases by mycelial fungi and actinomycetes].
abstract: The dextranase activity of cultures of mycelial fungi of different genera and actinomycetes from the Chromogenes species of the Actinomyces genus was studied. About one third of the mycelial fungi and 8% of actinomycetes showed dextranase activity. The resulting extracellular dextranases demonstrated on endotypic pattern of action on the substrate. Actinomycete dextranases were several times more active than fungal dextranases and exhibited a significant activity in the neutral and weakly alkaline medium. Highly productive strains that are promising as dextranase producers were isolated.
