Luteimonas cellulosilyticus sp. nov., Cellulose-Degrading Bacterium Isolated from Soil in Changguangxi National Wetland Park, China
A Gram-negative, motile, aerobic, and rod-shaped strain (MIC 1.5(T)) was isolated from soil in Changguangxi national wetland park. Growth occurred at 20-45 degrees C, at pH 6.0-8.0, and at 0-4.0% NaCl. Based on 16S rRNA gene sequence analysis, strain MIC 1.5(T) was related to were identified as Luteimonas dalianensis CGMCC 1.12191(T) (95.3%), Luteimonas padinae DSM 101536(T) (94.5%), Luteimonas huabeiensis DSM 26429(T) (94.1%), and Luteimonas mephitis DSM 12574(T) (92.5%). The DNA-DNA relatedness values between strain MIC 1.5(T) , and these strains were well below 31%. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. The DNA G+C content of strain MIC 1.5(T) was 66.3 mol%. Average nucleotide identity (ANI) and genome-to-genome distance (GGD) values between strain MIC 1.5(T) and L. dalianensis CGMCC 1.12191(T) were 65.39% and 29.52%, respectively. The quinone was identified as Q-8. The major fatty acids were iso-C-15:0, iso-C-15:0 3OH, and iso-C-17:0 3OH and summed feature 3 (C-16:1 omega 7c and/or iso-C-15:0 2-OH). Based on the phylogenetic, physiological, and chemotaxonomic results, strain MIC 1.5(T) represents a novel species of the genus Luteimonas, for which the name Luteimonas cellulosilyticus sp. nov. is proposed. The type strain is MIC 1.5(T) (= KACC 19469(T) = CCTCC AB 2017256(T)).
