Using fungi to produce renewable energy
Ebru Alazi ‘hacked’ an enzyme-producing system in the fungus Aspergillus niger in order to produce renewable energy more easily. She manipulated the fungus, making it produce more pectinases: enzymes mainly used in the food industry and in the production of renewable energy, such as biofuels. Promotion…
