Specific substrate consumption
The specific substrate consumption - symbol q s (dimension h –1 ) - is a key figure for describing fermentation processes . In the case of a microorganism culture, it describes the decrease in the substrate concentration per unit of time, based on the unit of mass of the biomass x formed :
The specific substrate consumption depends on exogenous and endogenous influences such as temperature, pH value , substrate concentration, the regulation of metabolism, etc.
