Chapter 5 - Current progress in the solid-state fermentation and utilization of agroindustrial residues for the production of biologically active secondary metabolites

Abstract

In the last few decades, there has been major technology advancement in solid-state fermentation (SSF) process. This chapter discusses about current progress in SSF and usage of agroindustrial waste or residues (AIW) as substrate for the production of biologically active metabolite. The modeling in SSF and types of bioreactor (BR) used in the SSF process is also discussed in this chapter. The progresses in enhancement of solid-state fermentation BR design have attracted the industries for a new process development. The continuous ongoing research in modeling and designing of bioreactor for the solid-state fermentation process is anticipated to lead commercial scale-up. Computational stimulation and mathematical model are important tools for developing the operational condition and control strategies to deal with the heat and mass transfer challenges; the computational fluid dynamics (CFD) is used in SSF bioreactors. SSF enhances the cost-effective importance to these AIW or by-products and at the same time resolves the issue of their removal, which may lead to pollution.
