RESUMO
The hemagglutinating activity of submerged mycelium and culture liquid for four strains of Lentinus edodes (Berk.) Sing [L. edodes (Berk.) Pegler] was studied in the search for lectins. The hemagglutinating activity of culture liquid was substantially higher, compared with mycelium. The carbohydrate-binding capacity of the agglutinins was established, and the lectin activity of extracts from mycelia grown on several agar media was elucidated in relation to fruiting. The lectin activity of L. edodes was examined at different morphogenetic steps: mycelium, brown mycelial film, primordium, and fruiting body. Hemagglutination titers at the brown film step were higher than in the mycelium, whereas activity at the primordial and fruiting bodies steps decreased. Lectins seem to be involved in the formation of hyphal aggregates of brown mycelial film (AU)
