Abstract
A slightly yellow-pigmented, Gram-stain-negative, rod-shaped bacterium, strain IMT-305T, was isolated from soil in Alabama, USA. Phylogenetic analysis based on the nearly full-length 16S rRNA gene sequence placed the strain in between the genera Pusillimonas, Parapusillimonas and Candidimonas with highest 16S rRNA gene sequence similarity to the type strain of Parapusillimonas granuli (97.5 %) and Candidimonas nitroreducens (97.4 %). The genomic G+C content of strain IMT-305T was 63.9 mol%. The main cellular fatty acids were C18:1ω7c, C17:0 cyclo, C16:0 and C16:1ω7c/iso-C15:0 2-OH (detected as summed feature 3). The polyamine pattern of strain IMT-305T contained the major compound putrescine and the betaproteobacterial diagnostic 2-hydroxyputrescine and the major respiratory quinone was ubiquinone Q-8. Predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, an unidentified aminolipid, an unidentified aminophospholipid and an unidentified lipid lacking any functional group. Based on phylogenetic, chemotaxonomic and phenotypic analyses a novel species within a new genus, Paracandidimonas soli gen. nov., sp. nov., is proposed. The type strain of Paracandidimonas soli is IMT-305T (=DSM 100048T=CIP 110902T=LMG 28740T=CCM 8599T).
