    Terriglobus is a genus in the phylum Acidobacteria in the family Acidobacteriaceae, order Acidobacteriales, class Acidobacteriia, subdivision 1. It currently comprises five species - Terriglobus roseus, Terriglobus saanensis, Terriglobus tenax, Terriglobus aquaticus, and Terriglobus albidus. Members of the genus are widely distributed in soils including rhizosphere soils and the phyllosphere, but is also found in freshwater and in association with insects. This genus encompasses bacteria that are chemo-organotrophs and have obligatory aerobic metabolism with an optimal growth in mildly acidic (pH ~5 to 6) and mesophilic (ca. 25 to 30°C) conditions. Colonies of Terriglobus are typically circular in form with a convex elevation and can be with or without pink pigmentation. These bacteria can use a range of different carbon sources, and nitrogen is attained by exogenous amino acids or ammonium chloride. Cells are non-motile, Gram-stain-negative with a length and width ranging from 0.8 to 2.5 µm and 0.4 to 0.9 µm, respectively. Some strains produce extracellular material, which can be visualized by microscopy or in liquid culture, generating a floc/clumping phenotype. The dominant fatty acids are iso-C15:0 and C16:1 ω7c/ C16:1 ω6c. The DNA G+C content (mol%) ranges from 57.3 to 63.2%.
