We investigated changes of bacterial composition before and after 3 days culture of fecal bacteria under the aerobic or acidic condition by the molecular methods. A part of intestinal bacteria was able to grow in Hank's balanced salt solution containing 10% fetal calf serum under the aerobic condition. As was expected we observed the significant increase of facultative anaerobes and decrease of obligate anaerobes. However, Bacteroides fragilis, an anaerobe, could regrow after 7 days aerobic culture. Terminal restriction length polymorphism analysis demonstrated the decreased number of peaks after the aerobic culture, suggesting loss of bacterial diversity. The maintenance at pH 4.5 in cultures resulted in the inhibition of bacterial growth, suggesting possible contribution of pH control to prevention of bacterial infection.
