Thermoanaerobacter tengcongensis is a rod-shaped, Gram-negative, anaerobic eubacterium that was isolated from a fresh water hot spring in Tengchong, China. Using a"whole-genome-shotgun"method, we sequenced its 2, 689, 445-bp genome from an isolate, MB4〓(Genbank Accession Number AE008691). The genome encodes 2, 588 predicted coding sequences . Among them, 1, 764 (68. 2％) are classified according to homology to other documented proteins, and the rest, 824 CDS (31. 8％), are functionally unknown. One of the interesting features of the T. tengcongensis genome is that 86. 7％ of its genes are encoded on the leading strand of DNA replication.

According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.
