Abstract (en)

[origin: WO2007131745A2] A method for the submerged cultivation of filamentous organisms is described, where the formation of cell agglomerates, mycelial assemblages and pellets, and the adhesion to abiotic surfaces is reduced or prevented during the cultivation through the presence of particles which are insoluble or only partly soluble in the cultivation liquid and have a size of up to a few millimetres. With this method it is possible to overcome the problems hitherto in the biotechnological use of filamentous organisms.
