Solid‐State Fermentation, Microbial Growth Kinetics

Abstract

In solid‐state fermentation, microorganisms grow on moist solid substrates in the absence of free water. The absence of free water makes the system quite different from submerged liquid fermentations and makes solid‐state fermentation superior for the production of some products. Understanding and modeling microbial growth kinetics and transport phenomena are essential to the development of large‐scale solid‐state fermentation technology. However, compared with submerged liquid fermentation, relatively little is known about the best ways to design and operate solid‐state fermentation bioreactors for large‐scale processes. This article summarizes the current state of development of modeling of solid‐state fermentation processes.

Assessment of Polysaccharide and Biomass Production from Three White-Rot Fungi by Solid-State Fermentation Using Wood and Agro-Industrial Residues: A Kinetic Approach

“…Manganese peroxidase Equation 1intended to describe the cell biomass dynamics that corresponded to a logistic model modified by Mitchell et al [73] and was successfully applied to the growth of the white-rot fungus G. frondosa in a previous work [74]. The variation of the reducing sugars is described by Equation 2, involving a constant production factor that modifies the growth rate; thus, the change of these sugars had a better fit to the growth rate than to the cell biomass itself.…”

Optimization of Fungal Rennet Production by local isolate of Rhizomucor nainitalensis Under Solid Substrate Fermentation system

“…They also require smaller space than shaker-equipped cylindrical reactors. These characteristics make SSF ideal for use in developing as well as industrial countries [24,25].…”
