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

Studies on a N-acetyl-β-D-glucosaminidase produced by Fusarium oxysporum F3 grown in solid-state fermentation
Konstantinos Gkargkas,Diomi Mamma,Georgi Nedev,Evangelos Topakas,Paul Christakopoulos,Dimitris Kekos,Basil J. Macris +6 more
TL;DR: In this paper, two isozymes of N -acetyl-β-d-glucosaminidase were isolated from the culture filtrate of Fusarium oxysporum F3 and were subjected to ammonium sulphate fractionation followed by anion exchange, gel filtration, hydrophobic interaction and cation exchange chromatography.
