Investigations with the mycelium forming bacterium Streptomyces hygroscopicus IMET JA 6599 in glucose‐limited chemostat cultures gave a maintenance coefficient of m = 0.031 h −1 . This low maintenance coefficient corresponds to those of moulds ( RIGHELATO et al. 1971). With a simple model structured in active and inactive biomass ( x 1 and x 2 ) it was tried to explain the low maintenance coefficient of S. hygroscopicus in relation to nonfilamentous growing microorganisms. The model contains the transition rate k , which describes the transition of active biomass in inactive one and the decay rate β, which considers the decay of hyphae. The model was used to study the influence of β on the maintenance coefficient and it was shown that maintenance metabolism can be simulated by the parameter β alone.
