I once read a comment from an expert in that field who said that it was essentially impossible to prevent contamination, and that they had to constantly test and then shut down and sanitize when they discovered a different species of algae in their system.

How do you mitigate that issue? (And good news if you have a solution, that same person said they figured whoever solved that problem would be the world's first trillionaire).

Mitigation strategies are varied, you basically cannot guarantee there will not be any contamination if you are doing any kind of scale. We are looking at polycultures/consortiums (robust ecosystems inside one reactor), various filtration systems and high frequency monitoring. There are some others we won't publish (yet)
