How are fermentors different from photobioreactors?
• Fermentors are similar to bioreactors in that they are closed or semi closed systems used for the production of biomass. However, fermentors utilize an organic source of carbon (e.g., sugar) as the source of energy and carbon instead of light and photosynthesis. Fermentors can usually achieve much higher biomass than a photobioreactor, but the cost per unit weight is usually much higher due to cost of supplying the fixed carbon source.
