Resumo

A bacterial strain, designated T16E-198T, was isolated from the rhizosphere of tomato plant collected from a farm on Buyeo-gun, Chungcheongnam-do, South Korea. The strain was aerobic, Gram-stain-negative, rod-shaped, non-flagellated and yellow-pigmented. Strain T16E-198T was mesophilic, catalase- and oxidase-positive and with flexirubin-type pigments. A phylogenetic tree based on 16S rRNA gene sequences showed that strain T16E-198T formed a lineage with Parafilimonas terrae 5GHs7-2T, sharing highest sequence similarity of 98.4 % with it and less than 93 % with all the other validly published species. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G. The predominant menaquinone was MK-7. The polar lipids were phosphatidylethanolamine, one unknown aminophospholipid, five unknown aminolipids and five unknown lipids. The DNA G+C content was 41.2 mol%. On the basis of the phenotypic, phylogenetic and chemotaxonomic data presented, strain T16E-198T is considered to represent a novel species of the genus Parafilimonas, for which the name Parafilimonas rhizosphaerae sp. nov. is proposed; the type strain is T16E-198T (=KACC 18786T=JCM 31601T).
