Document Summary
As they are growing, oxidizing metals, they are going to use that as a substrate, they are a huge problem to infrastructure. If they get colonized by biofilms, they require inplant. Biofilms may be composed of a single species or a several collaborating species: As they start t divide they form colonies. The numbers are increasing due to quorum. We used to believe prokaryotic acted alone now we know they utilize a complex language (or several languages) to sense the presence of their friends (or enemies) within the community and to trigger their behaviours accordingly. Quoram sensing refers to the process where bacterial cells work together at high density. It turns on various genes; more than chemical; more than one language. Quoram; producing bioluminescence, using bacteria for survival. Mediated by this compounded (homoserine lactate family) need to know this. A disease causing pathogen, if you wait for biofilm, its more difficult to clear.
