[Screening of yeast-producers of alpha-L-rhamnosidase].

Screening of producers of alpha-L-rhamnosidase among 331 yeast strains (representatives of 12 genera and 17 species) has been performed. A capacity to synthesize the enzyme was revealed in 45% of the studied strains with activity 0.01-0.

[Characteristics of three species of genus Debaryomyces Lodder & Kreger-van Rij].

A taxonomic state of the collection strains of three marketable species of genus Debaryomyses has been specified. Sources of their isolation have been analyzed and a list of econiches where the yeast occur has been supplemented. The properties have been found which are recommended to be used as additional for differentiation of D.
