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 xylanase by thermophilic melanocarpus albomyces IIS-68
TL;DR: Melanocarpus albomyces IIS-68, a thermophilic fungus was used for the production of extracellular xylanase on various agroresidues in solid-state fermentation (SSF), and studies with electron micrographs indicated that culture filtrate proteins were able to degrade wall polymers.

Production of fungal antibiotics using polymeric solid supports in solid-state and liquid fermentation
TL;DR: This method, mixed-phase fermentation (fermentation with an inert solid support bearing liquid medium), exploited the increase in surface area available for fungal growth on the supports and the tendency of some microorganisms to adhere to solid surfaces, possibly mimicking their natural growth habits.

Microbiological Production of Carotenoids. I. Zygospores and Carotene Produced by Intraspecific and Interspecific Crosses of Choanephoraceae in Liquid Media
TL;DR: It is reported that plus and minus strains of Choanephora cucurbitarum were capable of forming zygospores when grown together in liquid medium in shaken flasks, and yields of 960 t/g/g of 8-carotene in dry mycelium were found.
