从非洲的一口油井中分离到一株新的嗜热、降解木聚糖、严格厌氧的杆状细菌SEBR 7054（T）。基于外鞘（托加）的存在和16 S rRNA序列分析数据，该微生物被鉴定为Thermotoga属的成员。菌株SEBR 7054（T）具有侧生鞭毛，G+C含量为50 mol%，能从葡萄糖中产生微量乙醇，但不产生乳酸，在70 ℃ 0 ~ 0.2%NaCl条件下生长最佳。因此，我们认为菌株SEBR 7054（T）是Thermotoga属一新种Thermotoga hypogea sp，nov. hypogea是SEBR 7054（= DSM 11164）。
A new thermophilic, xylanolytic, strictly anaerobic, rod-shaped bacterium, strain SEBR 7054(T), was isolated from an African oil-producing well. Based on the presence of an outer sheath (toga) and 16S rRNA sequence analysis data, this organism was identified as a member of the genus Thermotoga. Strain SEBR 7054(T) possessed lateral flagella, had a G+C content of 50 mol%, produced traces of ethanol from glucose but no lactate, and grew optimally in the presence of 0 to 0.2% NaCl at 70 degrees C, Its phenotypic and phylogenetic characteristics clearly differed from those reported for the five previously validly described Thermotoga species. Therefore, we propose that strain SEBR 7054(T) is a member of a new species of the genus Thermotoga, Thermotoga hypogea sp, nov. The type strain of T. hypogea is SEBR 7054 (= DSM 11164).
