    The culture filtrate of Ceratocystis fagacearum contains a mannan that produces some symptoms similar to oak wilt in red oak seedlings and cuttings. The mannan has a high molecular weight and a skeleton of α- (1 → 6) linked mannose units with considerable branching. Some similarities to commercial yeast mannan have been observed.
