An empirical model was developed to describe a growth profile occurring in solid-state fermentation (SSF), namely that consisting of an initial period of rapid acceleration followed by an extended period of deceleration. This kinetic profile is not a

Membrane overcultures of Rhizopus oligosporus were shifted from 37 to 50 degrees C for 10 h and then returned to 37 degrees C, mimicking the temporal temperature profiles which typically occur in SSF due to heat transfer limitations. Analysis with a

Membrane filter culture was used to relate O2 uptake with direct biomass measurement of Rhizopus oligosporus in solid-state fermentation (SSF). Overall values of YX/O and mO were 0.782 mg biomass mg O2−1 and 0.0413 mg O2 mg biomass−1 h−1, respe

Step changes in the gas environment and temperature during membrane culture of Rhizopus oligosporus were made to mimic those changes which arise during solid-state fermentation due to mass and heat transfer limitations. A decrease of O2 concentration

For leaching of the acid protease produced by Rhizopus oligosporus in rice bran, a leaching solution of pH 7 gives optimal recovery, although the enzyme is more stable at pH 4. A contact time of 60 min is sufficient for extraction. Recovery is enhanc

SUMMARY: Secretion of the extracellular Rhizopus carboxyl proteinase (EC 3.4.23.6) by Rhizopus oligosporus is repressed in the presence of low-molecular-mass sources of nitrogen, sulphur and carbon. Proteinase is secreted when the medium is deficient

This chapter has shown how the basic empirical kinetic equation is written, and how the parameters of the equation can be written as functions of the key environmental variables. The next chapter extends the discussion to how we can model the effects
