Representative strains of @entity3069 , @entity4594 and @entity3069 scrofulaceum (MAIS) grew at equal rates in laboratory medium at 21% (air) and 12% @entity26 . Growth in 6% @entity26 proceeded at a 1.4-1.8-fold lower rate. Colony formation was the same at 21% (air) and 6% @entity26 . The MAIS strains survived rapid shifts from aerobic to anaerobic conditions as measured by two experimental approaches (Falkinham (1996) [1]). MAIS cells grown aerobically to log phase in broth were diluted, spread on agar medium, and incubated anaerobically for up to 20days at 37  C. Although no colonies formed anaerobically, upon transfer to aerobic conditions, greater than 25% of the colony forming units (CFU) survived after 20days of anaerobic incubation (Prince et al. (1989) [2]). MAIS cells grown in broth aerobically to log phase were sealed and vigorous agitation led to @entity26 depletion (Wayne model). After 12days anaerobic incubation, @entity3069 and M. scrofulaceum survival were high (>50%), while @entity4594 survival was lower (22%). @entity3069 cells shifted to anaerobiosis in broth had increased levels of @entity8959 dehydrogenase and isocitrate lyase. Growth of MAIS strains at low @entity26 levels and their survival following a rapid shift to anaerobiosis is consistent with their presence in environments with fluctuating @entity26 levels.
