Several non-pigmented bacterial isolates, with an optimum growth temperature of about 50 degrees C, were recovered from the hot spring at São Gemil in Central Portugal. Phylogenetic analyses of the 16S rRNA gene sequence of strain SGM-6T indicated that this organism represents a new species of the gamma-subclass of the Proteobacteria that is closely related to the newly described slightly thermophilic species Thermomonas haemolytica. The major fatty acids of strains SGM-6T and SGM-7 are C15:0 iso, C16:0 iso, C11:0 iso and C11:0 iso 3OH. Ubiquinone 8 is the major respiratory quinone. The new isolates are strictly organotrophic and aerobic. Strain SGM-6T only assimilated D-glucose, D-maltose, D-cellobiose, D-furanose, L-glutamate, L-glutamine, L-lysine, L-proline, L-ornithine, acetate, L-glutamic acid and pyruvate of sixty-five carbon sources tested. Strain SGM-7 also assimilates L-serine, but does not assimilate L-ornithine. On the basis of the phylogenetic analyses, physiological and biochemical characteristics, we propose that strains SGM-6T and SGM-7 represent a new species most closely related to Thermomonas haemolytica for which we propose the name Thermomonas hydrothermalis.

嗜热热单胞菌 十一月,从葡萄牙中部温泉中分离出的一种新的略嗜热的γ-变形杆菌。

从葡萄牙中部圣基米尔的温泉中回收了几种无色素的细菌分离株,其最佳生长温度约为50摄氏度。对SGM-6T菌株16S rRNA基因序列的系统进化分析表明,该生物代表了一种新的变形杆菌γ亚类,与新描述的略嗜热的嗜热单胞菌嗜热单胞菌密切相关。SGM-6T和SGM-7菌株的主要脂肪酸是C15:0同,C16:0同,C11:0同和C11:0同3OH。泛醌8是主要的呼吸醌。新分离株严格是有机营养的和需氧的。仅菌株SGM-6T吸收了D-葡萄糖,D-麦芽糖,D-纤维二糖,D-呋喃糖,L-谷氨酸,L-谷氨酰胺,L-赖氨酸,L-脯氨酸,L-鸟氨酸,乙酸盐,L-谷氨酸和丙酮酸测试的六十五个碳源。SGM-7菌株也吸收L-丝氨酸,但不吸收L-鸟氨酸。根据系统发育分析,生理和生化特征,我们建议菌株SGM-6T和SGM-7代表与溶血嗜热单胞菌最密切相关的一个新物种,我们将其命名为Thermotheras hydrothermalis。
