title: alpha-Mannosidases of genera Aspergillus and Rhizopus. Activity and capacity to utilize Saccharomyces cerevisiae mannan of the best alpha-mannosidase producer Aspergillus flavus Link 69.
abstract: Strains of fungi imperfecti of genera Aspergillus and Rhizopus were tested for the ability to produce alpha-mannosidases. The most suitable alpha-mannosidase producer of a total of 20 strains under study was Aspergillus Ravus Link 69. The parameters studied during the cultivation included the growth rate expressed as cell dry weight, alpha-mannosidase activity of the extracellular medium with p-nitorphenyl alpha-D-mannopyranoside as substrate, and utilization of Saccharomyces cerebisiae mannan via its disappearance from the cultivation medium.
