Different PCR-denaturing gradient gel electrophoresis (DGGE) protocols were employed to investigate bacterial communities in a high temperature and water flooded petroleum reservoir in Dagang oil field, China. Bacterial universal primers sets frequently used in PCR-DGGE were evaluated. Three primers sets P1 (341F-GC and 534R), P2 (341F-GC and 907R) and P3 (1055F and 1406R-GC) showed different DGGE patterns. Good separation and quality of patterns were obtained in DGGE analysis with the set P3. A total of 12 DNA fragments were excised from the DGGE gels and their sequences were determined. Clustering analysis of the DGGE profiles showed that bacteria in this petroleum reservoir belonged to four clusters. These results indicate that the procedure of DGGE analysis with the primer P3 (1055F and 1406R-GC) is suitable for investigating microbial community in petroleum reservoirs.
