FIG. 2.

Analysis of 16S rRNA gene fingerprints from the highest positive dilutions of MPN series. As an example, results obtained with a sample from 24 April 2001 are shown. On this date, cAMP did not affect the cultivation success. (A) Variability of fingerprints recovered in four different parallels of media containing cAMP or AMP. Arrows indicate fingerprints recovered from media containing cAMP as well as AMP. Asterisks indicate unique fingerprints. (B) Effect of incubation temperature (left panel) and oxygen partial pressure (right panel) on the phylotypes obtained in the highest positive dilutions of media supplemented with either cAMP or AMP.
