That's the mind-blowing thing for me about this article. The idea is that it can't compete with other organisms out in the wild. Out in the wild, other organisms reproduce too quickly, are too aggressive, devour these bacteria, etc. But these bacteria have something that allows them to survive in a clean room's extreme environment, something that kills off other more competitive organisms. This is the very definition of niche.
