Biotechnology using Basidiomycetes


Basidiomycetes can be cultured in strirred tanks or in fixed bed reactors. Product yields depend on a set of parameters. Unexpected is the modification of the exoproteom by UV-light, for example with Nidula niveo-tomentosa. Gas stripping has been successfully applied for the production of volatile flavours, such as perillene. A bioreactor with closed gas loop prevents loss of substrate and product which is otherwise bound to occur due to volatility. For the separation and purification of proteins and enzymes the isoelectric foam fractionation has been established.
