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

Interaction of transport resistances with biochemical reaction in packed-bed solid-state fermentors: effect of temperature gradients.
TL;DR: The temperature gradients caused by heat transfer resistances were reduced considerably with corresponding increases in enzyme activity and the problem of heat accumulation during the course of fermentation has been alleviated to a considerable extent using a packed-column bioreactor with forced aeration.

Biosynthesis of glucoamylase from Aspergillus niger by solid-state fermentation using tea waste as the basis of a solid substrate
TL;DR: Tea waste, supplemented with minerals, was used as the solid substrate for the synthesis of glucoamylase by a strain of Aspergillus niger NCIM 1248 to choose among different carbon sources and malt extract gave the highest enzyme titre.

Production of aflatoxin on wheat and oats: measurement with a recording densitometer.
TL;DR: A densitometric method for reading thin-layer chromatographic plates is described; this is more objective and more accurate than the visual methods previously used for the determination of all four aflatoxins.

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.
