摘要: A previously derived population model describing the average properties of hyphal elements in submerged cultures filamentous fungi was revised, and a term for influence fo spore germination on total length added. The from general balance distribution function elements. Based experimental data model, simple kinetic expressions germination, tip extension, branching, break-up were set up. It is concluded that can be quantified by three parameters: (1) time at which initiated, (2) terminates, (3) fraction viable spores suspension. frequency described with B-distribution. For growth kinetics it branching closely correlated tip-extension rate saturation respect to length. Finally, fragmentation linearly related energy input bioreactor, effective
