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

Design of solid state fermentor for production of fungal metabolites on large scale.
TL;DR: A large scale solid state fermentor of 150 tray capacity with appropriate control system was designed in this article, which gave better productivity even at higher scale of operation as compared to lab and large scale units of similar type and largely overcomes some operational problems.

TL;DR: The results are not in favor of an antagonistic effect of OTB with respect to OTA action, at least on the level of cellular protein synthesis.

Enrichment of wheat bran by rhodotorula gracilis through solid-state fermentation
TL;DR: The potential oil-producing yeast Rhodotorula gracilis was found to produce higher yields of biomass and lipids in a nitrogen-limited and economically cheaper medium and did not produceα-amylase, amyloglucosidase and cellulolytic enzymes for the breakdown of wheat bran.

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.
