【 摘 要 】

Fifty-six strains of Basidiomycetes, including native Brazilian fungi isolated from different ecosystems and edible mushrooms, were screened for production of exopolysaccharides and biomass in submerged culture. Agaricus sp. (CCB 280) and Oudemansiella canarii (Jungh.) Hohn (CCB 179) were the highest exopolysaccharide producers (6.01 and 3.54 g dry w./l respectively) after 7 days of incubation. The best producer of biomass was Schizophyllum commune Fr.:Fr. (CCB 473) with 16.68 g dry w./l in 14 days of incubation. When the culture filtrate was submitted to freezing prior to polysaccharide precipitation, a gelatinous fraction was formed.
