摘要：

The filamentous fungus Trichoderma reesei which is known to secrete high amounts of cellulolytic enzymes was found to produce a massive amount of fibrous material at the outer surface of the cell wall as observed by ultrahigh-resolution low-voltage scanning electron microscopy. Using transmission electron microscopy, the cell wall ornamentation of the hyper-cellulosic mutant PC-3-7 was found to be less massive and much thinner than for QM9414. A significant amount of fibrous material was produced in Avicel-grown cultures that were less abundant in glucose-grown cultures and Avicel was occasionally found entangled within the cell wall-associated fibrous layer.
