sp. nov., a novel endophytic bacterium isolated from species.

Two facultatively aerobic, Gram-stain-positive, rod-shaped, endospore-forming, endophytic bacteria, designated SGZ-1009 and SGZ-1014, were isolated from the plant sp. Strain SGZ-1009 grew at 5-50 °C, pH 4.5-11.0 and tolerated up to 4.5% NaCl (w/v), while strain SGZ-1014 exhibited growth at a temperature range of 10-50 °C, pH range 4.5-11.0 and tolerated up to 4.5% NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these two strains belong to the genus , closely related to the reference type strain of DSM 100576 (similarity of 97.0%). The genomic relatedness values for both strains, SGZ-1009 and SGZ-1014, compared to their closest reference strain DSM 100576, were 81.6% for average nucleotide identity and 26.0% for digital DNA-DNA hybridization, suggesting strain SGZ-1009 represents a novel species. The genomic DNA G+C content of strain SGZ-1009 was 46.4%. Both strains shared anteiso-C (55.9%) as the predominant fatty acid, menaquinone-7 as the major respiratory quinone and diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as the major polar lipids. Based on these results, strains SGZ-1009 and SGZ-1014 represent a novel species of , for which the name sp. nov. is proposed. The type strain is SGZ-1009 (=MCCC 1K08892=GDMCC 1.4280=KCTC 43677=JCM 36670).
