概要

[編集]

グラム陽性の非胞子形成桿菌であり、細胞の大きさは0.3~0.5×0.9μmである[1]。運動性と非運動性、並びにカタラーゼ陽性と陰性のどちらも存在する[16]

コロニーは黄色または白褐色である。偏性好気性且つ従属有機栄養性である。硝酸塩を利用しない。

主要なユビキノンはQ-10である。主要な脂肪酸は18:1、飽和脂肪酸16:0及び16:1である。主要な2-ヒドロキシ脂肪酸は、2-OH 14:0、2-OH 15:0、または 2-OH 16:0である。

GSLが存在する。スペルミジンが主要なポリアミン成分である。特徴的な16S rRNAシグネイチャー配列は、52:359 (C:G)、134 (G)、593 (U)、987:1218 (G:C)及び990:1215 (U:G)である。土壌や地下水に生息する[1]。DNAのGC含量は63.3–66.4 mol%である[17]
