PBR is an enclosed, lighted, algal culture vessel designed for controlled production of algae.
Photo bioreactors, have several major advantages over open ponds, they can:
Statement 1: Prevent contamination: One of the biggest problems with opens ponds (in my view anyway) is they are susceptible to contamination from invading and/or native species. In a PBR all inputs are completely controlled by you, not chance or nature. This is a HUGE advantage.
Allow you to grow algae in any climate: This is one of the main reasons for a PBR. It allows you to grow algae easily and cheaply in almost any climate. Open ponds are an unacceptable alternative in many colder climates.
Bioreactors offer better control over existing conditions: Since you’re controlling all the inputs, you can also (better) control the existing conditions of your algal experiments. Meaning climate, light, temperature, Ph balance, nutrients, etc.
Statement 2: Permit higher cell concentrations: Because you’re controlling the parameters of the PBR, you can also control the density of your cell colonies. While possible in an open pond, it is much easier in a PBR.
However, it is costly, difficult to set up and requires technical expertise which is not easy to come by for an ordinary algae farmer with limited resources.
