I can't imagine any reason for the anerobes to die. Well, perhaps a couple, temperature or overcrowding (build up of wastes). The circulation shouldn't be a factor. Anerobes don't require air (hence the name). In a microbiology lab, anerobes, such as Clostridium sporogenes (or botulinum) are cultured by stabbing media to innoculate it and then placed in an incubator. As long as they have food available (and they live off virtually anything) they thrive, until waste buildup requires innoculating a new culture. -- Hal O'Connell decvax!utzoo!dciem!nrcaer!cognos!halo Cognos Incorporated P.O.
