✦ Synopsis

The broth rheologies and morphologies of three actinomycetes (Saccharopolyspora erythraea, Actinomadura roseorufa, and Streptomyces rimosus) in submerged culture have been examined. The rheology of all the broths became pseudoplastic as soon as significant growth occurred with the power law index, n, falling to 0.20 to 0.25. The consistency index, K, rose with biomass concentration although in some instances it fell later in the fermentation. The mean main hyphal lengths of all cultures were in the range, 15 to 25 pm, and did not alter greatly even when large changes in K were occurring. @ 1995 John Wiley & Sons, Inc.

The microscopic morphology of Trichoderma reesei OM 9414, growing in submerged culture, was studied by image analysis. The morphology was characterized by the total hyphal length, the total number of tips, the number of actively growing tips, and the length of the main hypha. To describe the growth

The morphology of filamentous microorganisms in submerged culture is of great interest. On the one hand, morphology influences rheology and mass transfer in the fermentation broth. On the other hand, morphology could be a visible expression of physiology and metabolism of the microorganisms. An algo
