TLDR
A unique method is described by which large yields of secondary metabolites arc produced on solid substrates using Aspergillus and Penicillium species, which prevents sporulation of the fungus and makes recovery of the product easier than in conventional liquid media.Abstract:
A unique method is described by which large yields of secondary metabolites arc produced on solid substrates. The process involves the use of moist substrates which are continuously agitated in appropriate fermentation equipment. The amount of agitation, aeration, and moisture can be varied. Extremely high yields of secondary metabolites such as ochratoxin and aflatoxin were obtained using Aspergillus and Penicillium species. The process prevents sporulation of the fungus and because of the nature of the solid substrate makes recovery of the product easier than in conventional liquid media. The substrates include rice, corn, wheat, and other cereals.read more

Production of Secondary Metabolites by Solid-State Fermentation
TL;DR: Physiology in SSF shows several similarities with physiology in liquid medium, so similar strategies must be adapted for efficient processes, but there are certain particularities of idiophase in solid medium which dictate the need for special strains.

Solid‐state fermentation of sweet sorghum to ethanol
TL;DR: Solid‐state fermentation of chopped sweet sorghum particles to ethanol was studied in static flasks using an ethanol tolerant yeast strain to investigate the influence of various process parameters, such as temperature, yeast cell concentration, and moisture content on the rate and extent of ethanol fermentation.

Production of lipase by Candida rugosa in solid state fermentation. 1: determination of significant process variables
TL;DR: Immobilization of lipase on rice bran ( in situ ) has been found possible and the particle size and oil content of the bran and the addition of urea and maltose have a pronounced effect on the production oflipase.
