Seven thermophilic anaerobic bacteria which ferment xylan were isolated from natural geothermal features in the western United States. Typically, these strains were Gram-negative non-sporeforming rods with an unusual double-layered cell wall which resembled that observed in Thermobacteroides acetoethylicus. The strains differed from known thermophilic anaerobes in their ability to utilize a very wide variety of carbohydrates and in their ability to grow in a chemically-defined medium and/or at pH 3.5. Four of the strains contained cryptic plasmids of 1.2 or 1.5 X 10(6) daltons. The taxonomic characteristics of the strains are discussed in terms of their relatedness to those of Thermoanaerobium, Thermoanaerobacter, and Thermobacteroides species.
从美国西部的天然地热区分离出七株能发酵木聚糖的嗜热厌氧细菌。通常，这些菌株为革兰氏阴性、无芽孢杆菌，具有不寻常的双层细胞壁，类似于在乙酰丁酸热杆菌中观察到的细胞壁。这些菌株与已知嗜热厌氧菌的不同之处在于，它们能够利用种类繁多的碳水化合物，并且能够在化学成分明确的培养基中生长和/或在pH值为3.5的条件下生长。其中四株菌株含有1.2或1.5×10⁶道尔顿的隐蔽质粒。根据这些菌株与嗜热厌氧菌属、嗜热厌氧杆菌属和热杆菌属物种的亲缘关系，讨论了它们的分类学特征。
