[Action of various beta(1-3)-D-glucanases on the wall of yeasts: taxonomic applications].

Purified beta-(1-3)-D-glucanases (from Aspergillus nidulans, Badidiomycetes sp. QM 806, Trichoderma viride) are used to release protoplasts from various yeasts. Two of them may prove taxonomic correlation. The enzyme of Basidomycetes sp. releases protoplasts from Ascomycetes, the enzyme of T. viride releases protoplasts from Ascomycetes and Heterobasidiomycetes; none of them acts on the Basidiomycetes.
