Waste streams to food – a biochemical approach


Area: downstream processing, biocatalysis
Project Start: 23.10.2013
Supervisor(s): Prof. Dr.-Ing. Gerhard Schembecker
University: Dortmund


Project overview

In the food industry, large amounts of biogenic side products cannot as yet be processed further and are considered waste streams. These biogenic waste streams are preferably used as feed stock for animals or for thermal energy production. To avoid this loss, a promising approach is the utilization of waste streams as substrates for biotechnical processes. Some edible basidiomycota are already being industrially bred and used in Asia as medicinal fungi.

The objective of this project is the application of different biogenic waste streams for the submerged cultivation of the fungus Hericium erinaceus. The focus is to optimise the growth of the fungus as well as the stimulation of production of erinacines. These molecules are thought to cause the medicinal effect of the fungus. Besides the development of an optimal set up for fermentation, established methods of downstream processing are performed and modified to purify the molecules of interest.
