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 degrees C and at pH 6-8 on R2A agar. The major cellular fatty acids were summed feature 3 [comprising C-16:1 omega 7c and/or C-16:1 omega 6c (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 gene 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)(=KCTC 23942(T)=CECT 8102(T)).
