A taxonomic study was carried out on strain GCS-AE-31T,which was isolated from a phenol-degrading consortium,enriched from coking wastewater activated sludge of Beijing Shougang Company Limited during the screening of phenol-degrading bacteria.Cells of strain GCS-AE-31T were Gram-negative,short rods,gliding motile,oxidase-/catalase-positive.Growth was observed at salinities from 0 to 3%and at temperatures from 10 to 37 ℃.On the basis of 16S rRNA gene sequence similarity,strain GCS-AE-31T was most closely to Pedobacter saltans LMG 10337T (96.17%),but it showed low similarity to all other species of genus Pedobacter (89.28-92.45%).It also showed low 16S rRNA similarity to all other species of the family Sphingobacteriaceae (87.25-92.45%).The dominant fatty acids were iso-C15:0 (34.5%),Sum In Feature 3 (C16:1ω7c/C16:1ω6c,18.6%),anteiso-C15:0 (7.1%) and iso-C17:0 3-OH (6.4%).The menaquinones were MK-7 (95.5%) and MK-6 (4.5%).The polar lipids were phosphatidylethanolamine,three aminolipids and three unknown phospholipids.Sphingolipid was present.The G+C content of the chromosomal DNA was 36.2 mol%.According to its phylogenetic position and phenotypic traits,the novel strain could not be assigned to the genus Pedobacter,it should be classified as a novel species of a new genus in the family Sphingobacteriaceae,for which the name Pseudopedobacter beijingensis gen.nov.,sp.nov.is proposed (type strain GCS-AE-31T =MCCC 1A01299T=CGMCC NO 1.12329T=LMG 27180T).The misclassified species Pedobacter saltans is transferred to the new genus as Pseudopedobacter saltans com.nov.(type strain LMG 10337T = MCCC 1A06472T = DSM 12145T=CCUG 39354T=CIP 105500T=JCM 21818T=NBRC 100064T).
