Steroidobacter agaridevorans (a.ga.ri.de.vo'rans. Malayan n. agar agar [algal polysaccharide]; N.L. neut. n. agarum agar; L. pres. part. adj. devorans consuming, devouring; N.L. part. adj. agaridevorans agar-devouring).
Its colonies are smooth and pale yellow in color. Cells are Gram-negative, non-motile, rod-shaped with a width of 0.4–0.6 μm and length of 1.5–2.5 μm (type strain), and non-spore-forming. Most cells are included in a fibrous polysaccharide matrix. It does not grow under anaerobic conditions. Cytochrome oxidase and catalase activities are positive. It exhibits the ability to degrade agar. Diffusible metabolites from Rhizobiales bacteria are required for regular growth. The growth of the type strain occurs at 15–40°C (optimum 35°C), pH 6.0–12.0 (optimum pH 7.0–7.5), and NaCl concentrations of up to 2% (w/v) (optimum 1%). The dominant whole cell fatty acids are C16:0, iso-C15:0, iso-C17:0, and summed features 3. The main quinone is Q-8. The genomic DNA G+C content of the type strain is 62.3 mol%. Substrate utilization of the type strain by Biolog GN2 is positive for N-acetyl-D-galactosamine, L-alaninamide, γ-aminobutyrate, D-cellobiose, α-cyclodextrin, dextrin, D-galactose, gentiobiose, D-glucose, L-glutamate, glycyl-L-glutamate, L-histidine, β-hydroxy butyrate, α-D-lactose, L-leucine, maltose, methyl β-D-glucoside, L-phenylalanine, L-proline, L-rhamnose, D-trehalose, turanose, tween 40, and tween 80, weakly positive for N-Acetyl-D-glucosamine, α-Ketoglutarate, D,L-Lactate, and Succinamate, and negative for acetate and citrate. The type strain is Steroidobacter agaridevorans SA29-BT (JCM 33368T=KCTC 72223T), which was isolated from a rhizosphere soil sample.
