Microorganism used as source of single cell protein have many advantages over the traditional methods for producing proteins for food which includes all the following except:
1. Microorganisms have a much higher growth rate
2. Microorganisms usually have a much higher protein content of 30–70% in the dry mass than vegetables or grains.
3. Some microorganisms can build vitamins and nutrients which eukaryotic organisms such as plants cannot produce.
4. Fast growing microorganisms such as bacteria and yeast have a high concentration of nucleic acid, notably RNA.
