Thermococcus strains TYST and TYT isolated from the Guaymas Basin hydrothermal vent site and previously described were compared by DNA-DNA hybridization analysis with the closest Thermococcus species in terms of physiology and nutritional aspects. On the basis of the new data and taking into consideration the molecular, physiological and morphological traits published previously, it is proposed that strains TYT and TYST should be classified as new species named Thermococcus aggregans sp. nov. and Thermococcus guaymasensis sp. nov., respectively. The type strain of T. aggregans is strain TYT (= DSM 10597T) and the type strain of T. guaymasensis is strain TYST (= DSM 11113T).
从瓜伊马斯盆地热液喷口处分离得到的嗜热栖热菌菌株TYST和TYT，之前已有描述，此次通过DNA-DNA杂交分析，将它们与在生理和营养方面最为接近的嗜热栖热菌种进行比较。基于新的数据，并考虑到之前发表的分子、生理和形态学特征，建议将菌株TYT和TYST分别分类为新物种，命名为聚集嗜热栖热菌（Thermococcus aggregans sp. nov.）和瓜伊马斯嗜热栖热菌（Thermococcus guaymasensis sp. nov.）。聚集嗜热栖热菌的模式菌株为菌株TYT（= DSM 10597T），瓜伊马斯嗜热栖热菌的模式菌株为菌株TYST（= DSM 11113T）。
