Abstract

A polyphasic taxonomic approach was used to characterize a novel bacterium, designated strain CC-YST705T, isolated from poultry manure sampled in Taiwan. Cells of strain CC-YST705T were aerobic, Gram-stain-negative, non-motile, non-spore-forming rods, displaying positive reactions for catalase, oxidase and β-glucosidase. Optimal growth occurred at 30 °C and pH 8. Strain CC-YST705T shared the highest (> 96.0%) pair-wise 16S rRNA gene sequence similarity with Pusillimonas noertemannii (96.7%), followed by Pusillimonas caeni (96.6%), Eoetvoesia caeni (96.1%) and Paracandidimonas soli (96.0%), and formed a distinct phyletic lineage associate with the clade that accommodated Pusillimonas species. The draft genome (3.1 Mb) having 57.4 mol % G + C content contained genes involved in the catabolism of aromatic hydrocarbons. The orthologous average nucleotide identity (OrthoANI) values were 62.8–73.1% (n = 8), 72.6 (n = 1), 71.5% (n = 1) compared within the type strains of the genera Pusillimonas, Eoetvoesia and Paracandidimonas, respectively. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified aminolipid, two unidentified phospholipids and five unidentified lipids. The major polyamine was spermidine. The dominating cellular fatty acids (> 5%) included C12:0, C16:0, C17:0 cyclo, C19:0 cyclo ω8c and 2 C14:0 3OH/iso-C16:1 I. Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, OrthoANI, digital DDH, and the phylogenomic placement, strain CC-YST705T is considered to represent a novel species of the genus Pusillimonas, for which the name Pusillimonas faecipullorum sp. nov. is proposed. The type strain is CC-YST705T (= BCRC 81285 T = JCM 34168 T).
