The results of our investigation on the microbial community of the high-temperature Dagang oilfield (P.R. China) are summarized. Detailed experimental data are provided on syntrophic acetate degradation by thermophilic associations, on the isolation of pure cultures from these associations, their physiological characteristics,
and reconstruction of microbial interactions during acetate degradation to methane. The microbial community of the high-temperature Dagang oilfield was investigated
by culture-based, radioisotope, and 16S rRNA gene techniques. Cultivable microorganisms (aerobic oil-oxidizing, anaerobic fermentative, sulfate-reducing, and
methanogenic) were found in formation water. Methanogenic enrichments were obtained in media both with Н2+CO2 and acetate.
