Biocatalysis and Bioprocessing

Research Leader: Dr S Malgas

Background: 
The Biocatalysis and Bioprocessing laboratory is focused on driving biorefinery for the bioeconomy through enzyme biotechnology. The laboratory focusses specifically on the application of enzymes and microorganisms in the food and feed sector, the production of fine chemicals and nutraceuticals from agricultural-derived plant waste. Industrial scaling-up of the research conducted by the laboratory would ultimately contribute to the development of sustainable processes, job creation and the production of value-added products, while avoiding the untenable disposal of agro-industrial wastes. Furthermore, the laboratory participates in projects involved in the testing of these agroindustrial waste derived phytochemicals as prebiotics, antioxidants, and antidiabetic and anti-obesity leads to manage life-style diseases and overall human health.
