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.
