A bacterial strain was isolated from pathogenic lesions of Acer campestre tree leaves from the Teutoburg Forest in North Rhine-Westphalia, Germany, by culture on non-selective agar plates. 16S rRNA sequencing revealed 100% similarity to Sanguibacter keddieii and Sanguibacter inulinus, as well as 99% similarity to Sanguibacter gelidistatuariae and Sanguibacter antarcticus. Here, we used genome-based taxonomy with the Type (Strain) Genome Server (TYGS), which suggests the isolation of a novel prokaryotic strain. According to TYGS-analysis, using whole genome digital DNA–DNA hybridization, only 65.5% similarity to the closest relative S. inulinus was revealed, suggesting a novel species. Growth was observed at both aerobic and anaerobic conditions. Bacterial cells depicted coryneform motile rods, with a length of 1.1–3.3 µm and a constant diameter of 0.5 µm. Cells did not form spores under the tested conditions and stain Gram-positive. Growth occurred between 0.5 and 4% NaCl (optimal: 1%), at pH 5.5–9.5 (optimal: 8.0–9.0). The strain was mesophilic with an optimal growth at 25 °C. Major cellular fatty acids of the novel strain were anteiso-C15 : 0 and C16 : 0.
