Abstract
The productivity of some external hydrolases was investigated about 82 strains of Basidiomycetes and it was suggested that a distributional pattern of enzyme activities was more or less correlated with the generally admitted systematic arrangement of Basidiomycetes.
There was no special correlation between the growth of fungi and the productivity of enzymes.
In Trametinae, Coriolinae and Coprinaceae, there were a number of strains with the high productivity of hydrolases.
In general, a number of strains of Aphyllophorales were richly productive of amylolytic, cellulolytic (C2 activity) and pectolytic enzymes; on the contrary, there were few strains of Agaricales with the high productivity of the enzymes mentioned above.
Xylanase and β-1, 3-glucanase were produced richly by a great number of strains of both Aphyllophorales and Agaricales. Trehalase and cellulolytic enzyme (Cx activity) were also produced by most strains of Basidiomycetes, even though their activities were not necessarily high.
As for proteolytic enzyme, most strains of Aphyllophorales showed high acid proteinase activity, whereas some strains of Agaricales had the high neutral or alkaline proteinase activity.
Lampteromyces japonicus was an exceptional strain of Agaricales and it seemed that the productivity of enzymes of the strain was much the same as that of strains of Aphyllophorales.
Trametes sanguinea and Irpex lacteus had high activities of the almost all enzymes investigated. In comparison of enzyme activities between the two, proteolytic activity of the former was higher than that of the latter, and pectolytic activity was the opposite case.
