Abstract
A Gram-negative, motile, aerobic, and rod-shaped strain (MIC 1.5T) was isolated from soil in Changguangxi national wetland park. Growth occurred at 20–45 °C, at pH 6.0–8.0, and at 0–4.0% NaCl. Based on 16S rRNA gene sequence analysis, strain MIC 1.5T was related to were identified as Luteimonas dalianensis CGMCC 1.12191T (95.3%), Luteimonas padinae DSM 101536T (94.5%), Luteimonas huabeiensis DSM 26429T (94.1%), and Luteimonas mephitis DSM 12574T (92.5%). The DNA-DNA relatedness values between strain MIC 1.5T , and these strains were well below 31%. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. The DNA G+C content of strain MIC 1.5T was 66.3 mol%. Average nucleotide identity (ANI) and genome-to-genome distance (GGD) values between strain MIC 1.5T and L. dalianensis CGMCC 1.12191T were 65.39% and 29.52%, respectively. The quinone was identified as Q-8. The major fatty acids were iso-C15:0, iso-C15:0 3OH, and iso-C17:0 3OH and summed feature 3 (C16:1ω7c and/or iso-C15:0 2-OH). Based on the phylogenetic, physiological, and chemotaxonomic results, strain MIC 1.5T represents a novel species of the genus Luteimonas, for which the name Luteimonas cellulosilyticus sp. nov. is proposed. The type strain is MIC 1.5T (= KACC 19469T = CCTCC AB 2017256T).
