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

Charushila Kumbhar,Milind Watve +1 more
TL;DR: The synthesis successfully links different functions of antibiotics with logical coherence and concludes that antibiotics serve a multitude of ecological functions and it is possible to visualize a pathway for the radiating functions.
