From:  Solid-state fermentation: an alternative for continuous and discontinuous production of bioactive compounds with biological activity

 Characteristics of continuous vs discontinuous processes [99, 100]

CharacteristicsContinuous processDiscontinuous process
Process operation efficiencyCan maintain constant production.The batch system has challenges due to conditions over time and process control.
Yield and productivityOffers greater productivity.Reduce productivity due to SSF factors, which may result in lower yields and undesirable products.
Microbial growth and sporulationThe continuous system can be designed to optimize the fermented material to obtain an adequate growth of microorganisms.Environmental conditions may affect microbial growth; thus, a lower biomass rate may result.
SubstrateSubstrate addition is done continuously during the process.At the beginning of the process, the substrate is added and no more is needed.
