An aerobic, Gram-stain-negative, rod-shaped bacterium, designated strain PGW1-R01 T , was isolated from fresh water from the Yeongju in the Republic of Korea. The strain grew optimally at 30 6C and at pH 6-8 on R2A agar. The major cellular fatty acids were summed feature 3 [comprising C 16 : 1 v7c and/or C 16 : 1 v6c (50.2 %) and iso-C 15 : 0 (24.8 %)]. The major respiratory quinone was MK-7. The G+C contents were 39.4 mol% and the predominant respiratory quinone was MK-7. Based on 16S rRNA

... phylogeny, the strain belongs to the genus Mucilaginibacter. The strain PGW1-R01 T was closely related to 'Mucilaginibacter ginsenosidivorax' (96.6 % sequence similarity), Mucilaginibacter lappiensis (96.4 %) and Mucilaginibacter flavus (96.4 %). On the basis of the evidence presented in this study, strain PGW1-R01 T represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter http://dx.doi.org/10.1601/nm.11437aquaedulcis sp. nov., is proposed. The type strain is PGW1-R01 T (5KCTC 23942 T 5CECT 8102 T ).
