[Isolation and characterization of a cellobiose dehydrogenase formed by a asporogenic mycelial fungus INBI 2-26(-)].

A nonsporulating fungus isolated from dioxine-containing tropical soils forms cellobiose dehydrogenase, when grown in media supplemented by a source of cellulose. The enzyme purified to homogeneity by SDS-PAGE (yield, 43%) had an M(r) of 95 kDa; its pH optimum was in the range 5.5-7.
