International training course on solid state fermentation

We present here some theoretical consideration on the correlation model between Biomass and respiration. The case of the growth of #Aspergillus niger$ on starchy substrate is discussed as an example of the application of the calculation of fermentation parameters. It is specially possible to calculate from the respiratory metabolism the specific growth rate, the maintenance, yields in biomass, metabolic products, and also heat evolved during the fermentation on basis of Oxygen Uptake Rate, CO2 evolved and the consumed substrate. In a second part we detail the equipment and methodology of the lab standardised method we developed for all physiological studies and optimisation of the culture conditions for SSF of fungi. Finally we illustrate the technique by the case of #A. niger$ and #Rhizopus oryzae$ cultivated on starchy SSF for showing the software developed for automatic calculation from the on line data obtained by CPG.
