Abstract

Two Gram-stain-negative, mesophilic, strictly aerobic, nonspore forming, and yellow-pigmented strains with rod-shaped cells, designated H21R20T and H23M41T, were isolated from the faeces of an Oriental stork (Ciconia boyciana). Based on 16S rRNA gene sequences, both strains showed the highest similarity (98.3−98.4%) to the type strain of Lysobacter concretionis. Phylogenetic analysis based on the 16S rRNA genes and 92 bacterial core genes showed that strains H21R20T and H23M41T were robustly clustered with L. concretionis Ko07T. Whole genome sequencing revealed that the genomes of both strains were approximately 2.9 Mb in size. The DNA G + C contents of the H21R20T and H23M41T strains were 67.3 and 66.6%, respectively. The two strains showed 80.1−81.7% average nucleotide identity with L. concretionis Ko07T. Strain H21R20T grew optimally at 30°C and pH 8.0 and in the presence of 0.5–3% (wt/vol) NaCl, while strain H23M41T grew optimally at 30°C and pH 7.0–8.0 and in the presence of 0–3% (wt/vol) NaCl. Both strains possessed iso-C15:0, iso-C16:0 and summed feature 9 (iso-C17:1 ω9c and/or C16:0 10-methyl) as the major cellular fatty acids, ubiquinone Q-8 as a predominant quinone, and diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine as the major polar lipids. A multifaceted investigation demonstrated that strains H21R20T and H23M41T represent novel species of the genus Lysobacter, for which we propose the names Lysobacter ciconiae sp. nov. and Lysobacter avium sp. nov. for strains H21R20T (= KCTC 82316T = JCM 34832T) and H23M41T (= KCTC 62676T = JCM 33223T), respectively.
