Abstract
A Gram-staining-negative, rod-shaped bacterium, strain HMD2169T, was isolated from a mesotrophic artificial lake in Korea. Strain HMD2169T grew in the presence of 0–3.0 % (w/v) NaCl, at pH 5–10 and at 20–37 °C. The predominant quinone of strain HMD2169T was ubiquinone (UQ)-8. The major fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, two unidentified aminolipids and two unidentified lipids. The DNA G+C content was 59.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD2169T was a representative of a lineage within the genus Chitinimonas . Strain HMD2169T was closely related to Chitinimonas taiwanensis (95.8 % sequence similarity) and Chitinimonas koreensis (94.6 %). On the basis of the evidence presented in this study, strain HMD2169T is a representative of a novel species of the genus Chitinimonas , for which the name Chitinimonas viridis sp. nov. is proposed with the type strain HMD2169T ( = KCTC 22839T = CECT 7703T).
