Modern biotechnology techniques enable large quantities of micro-organisms to be cultured for food.
There are two main methods- genetic modification and mycoprotein
MYCOPROTEIN
The fungus Fusarium is useful for producing mycoprotein, a protein-rich food suitable for vegetarians. The fungus is grown on glucose syrup in aerobic conditions and the biomass is harvested and purified
GENETIC MODIFICATION
Genetic modification could provide more food or food with additional nutritional value such as golden rice.
It is a genetically modified crop engineered to produce beta-carotene, a precursor to Vitamin A
