Paraflavitalea soli gen. nov., sp. nov., isolated from greenhouse soil.

A bacterial strain designated 5GH32-13 ^T was isolated from greenhouse soil in Yongin-city, Republic of Korea. Cells were Gram-stain-negative, strictly aerobic, motile rods of two different shapes. The strain was catalase-positive and oxidasenegative. Flexirubin-like pigments were not detected. β-Carotene was produced. The strain grew in the range of 10-37°C (optimum of 28-30°C) and pH 6-8 (optimum of pH 7) and tolerated up to 1% (w/v) NaCl (optimum of 0%). According to the 16S rRNA gene sequence comparison, strain 5GH32-13 ^T shared a sequence similarity of less than 96.0% with all validly named taxa, having the highest sequence similarity with Pseudoflavitalea soli KIS20-3 ^T (95.8%), Pseudoflavitalea rhizosphaerae T16R-265 ^T (95.4%), Flavitalea gansuensis JCN-23 ^T (95.3%), Pseudobacter ginsenosidimutans Gsoil 221 ^T (95.3%), and Flavitalea populi HY-50RT (95.2%). A phylogenetic tree showed that strain 5GH32-13 ^T was not grouped consistently into any specific genus. Its only polyamine was homospermidine, and its major fatty acids (> 10% of total fatty acids) were iso-C _15:0 , iso-C _17:0 3-OH, and iso-C _15:1 G. The strain's only respiratory quinone was MK-7, and its polar lipids were phosphatidylethanolamine, one unidentified phospholipid, six unidentified aminolipids and four unidentified lipids. Its DNA G + C content was 47.5 mol%. The results from chemotaxonomic, phenotypic and phylogenetic analyses indicated that strain 5GH32-13 ^T represents a novel species of a novel genus of the family Chitinophagaceae, and the name Paraflavitalea soli gen. nov., sp. nov. is proposed. The type strain is 5GH32-13 ^T (= KACC 17331 ^T = JCM 33061 ^T ).
