Thank you for pulling all that together and posting it here.
I am thinking these biofilm problems are a lot more prevalent than folks are thinking, and I hope this thread will carry on until we can define a consistently workable approach to identify, localize and dismantle them.
I am thinking that sound will also be a key to disassembling a biofilm colony, but I haven't worked it out yet. Something like an ultrasonic device used the way that Hulda Clark was using it (Sonicator).
BTW, am I the only one thinking this sounds like a jellyfish??? I know it sounds far out, but that idea keeps recurring to me. 8}
