Ac. Badino et al., Estimation of the rheology of glucoamylase fermentation broth from the biomass concentration and shear conditions, BIOTECH TEC, 13(10), 1999, pp. 723-726
Fermentation broths from nine Aspergillus awamori cultivations, carried out
under different agitation and aeration conditions and distinct initial sub
strate concentrations, were characterized using a continuous on-line rheome
ter. A single correlation between the consistency index (K) and the biomass
concentration (X), including the agitation (N) and aeration (Q) conditions
fitted the experimental data reasonably well, showing that the shear condi
tions imposed on the broth influence in a significant way the mycelial morp
hology and, therefore, the broth rheology.
