Mucilaginibacter auburnensis sp. nov., isolated from a plant stem Kämpfer, Peter and Busse, Hans-Jürgen and McInroy, John A. and Glaeser, Stefanie P.,, 64, 1736-1742 (2014), doi = https://doi.org/10.1099/ijs.0.060848-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A yellow-pigmented, Gram-negative, rod-shaped, non-spore-forming bacterium (strain JM-1070T) was isolated as a presumptive endophyte from internal stem tissue of a healthy corn stem. Phylogenetic analyses based on the 16S rRNA gene sequence placed strain JM-1070T in the monophyletic cluster of the genus Mucilaginibacter , with closest affiliation to the type strains of Mucilaginibacter composti (98 % similarity) and Mucilaginibacter calamicampi (97.2 %). 16S rRNA gene sequence similarity to type strains of other species of the genus Mucilaginibacter was 93.4–96.0 %. DNA–DNA hybridizations between strain JM-1070T and the type strains M. composti LMG 23497T and M. calamicampi CCUG 63418T showed low relatedness values of 13 % (reciprocal 18 %) and 52 % (reciprocal 54.4 %). Major respiratory quinones were menaquinones MK-6 and MK-7. The predominant fatty acids (>15 %) were iso-C15 : 0, iso-C15 : 0 2-OH/C16 : 1ω7c (measured as summed feature 3) and iso-C17 : 0 3-OH. Several other iso-branched and hydroxylated fatty acids were detected. The polar lipid profile was composed of the major components phosphatidylethanolamine and an unidentified aminophospholipid. The polyamine pattern contained predominantly sym-homospermidine. Characterization by 16S rRNA gene sequencing, physiological parameters and polyamine, ubiquinone, polar lipid and fatty acid compositions revealed that strain JM-1070T represents a novel species of the genus Mucilaginibacter . For this reason, we propose the name Mucilaginibacter auburnensis sp. nov., with the type strain JM-1070T ( = CIP 110694T = LMG 28078T)., language=, type=
