Abstract

|
|
A Gram-stain-negative, white-coloured, and rod-shaped bacterium, strain DR4-4T, was isolated from Daechung Reservoir, Republic of Korea, during Microcystis bloom. Strain DR4-4T was most closely related to Caenimonas terrae SGM1-15T and Caenimonas koreensis EMB320T with 98.1% 16S rRNA gene sequence similarities. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain DR4-4T and closely related type strains were below 79.46% and 22.30%, respectively. The genomic DNA G+C content was 67.5%. The major cellular fatty acids (¡Ã10% of the total) were identified as C16:0, cyclo C17:0, summed feature 3 (C16:1¥ø7c and/or C16:1¥ø6c), and summed feature 8 (C18:1¥ø7c and/or C18:1¥ø6c). Strain DR4-4T possessed phosphatidylethanolamine, diphosphatidylglycerol, and phosphatidylglycerol as the main polar lipids and Q-8 as the respiratory quinone. The polyamine profile was composed of putrescine, cadaverine, and spermidine. The results of polyphasic characterization indicated that the isolated strain DR4-4T represents a novel species within the genus Caenimonas, for which the name Caenimonas aquaedulcis sp. nov. is proposed. The type strain is DR4-4T (=KCTC 82470T =JCM 34453T).
