title: Paracoccus laeviglucosivoranssp. nov., an l-glucose-utilizing bacterium isolated from soil.
abstract: Strain 43PTwas isolated as an l-glucose-utilizing bacterium from soil in Japan. Cells of the strain were Gram-stain-negative, aerobic and non-motile cocci. The 16S rRNA gene sequence of the strain showed high similarity to that ofParacoccus limosus(98.5 %). Phylogenetic analyses based on 16S rRNA gene sequences revealed that this strain belongs to the genusParacoccus.Strain 43PTcontained Q-10 as the sole isoprenoid quinone. The major cellular fatty acids were C18: 1ω7cor C18: 1ω6cand C16: 0, and C18: 0, C18: 1ω9c, C10: 03-OH and summed feature 2 were detected as minor components. The DNA G+C content of strain 43PTwas 64.1 mol%. Strain 43PTcontained the major polar lipids phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminolipid and two unknown glycolipids. The DNA-DNA relatedness between strain 43PTand the six related type strains of the genusParacoccus, includingP. limosus, was below 23 %. Based on the chemotaxonomic and physiological data and the values of DNA-DNA relatedness, especially the ability to assimilate l-glucose, this strain should be classified as a representative of a novel species of the genusParacoccus, for which the nameParacoccus laeviglucosivoranssp. nov. (type strain 43PT= JCM 30587T= DSM 100094T) is proposed.
