isolated from Chinese hot spring, is a rod-shaped,Gram negative and anaerobic new extremely thermophilic bacterium.

The complete genome sequence of  

T.tengcongensis clone MB4T consists of  a 37.6%   GC-content 2,689,441, base pair  (bp)  circular ; chromosome that;  contains 2808 predicted coding regions, 1,481,(52.7%)   which  have  functional assignments and 1,327 (47.3%) of which are of unknown function.

Efficient metabolic  functions are      

predicted, with sugars as the principal energy and carbon source. Genome analysis also reveals that 30 genes have homology only in the genomes of other thermophilic Eubacteria and Archaea.
Of the Eubacteria sequenced to date, T. tengcongensis has the highest percentage (59.8%)of genes that are most similar to Bacillus halodurans.
