Arenimonas subflava sp. nov., isolated from a drinking water network, and emended description of the genus Arenimonas , measured by two different methods (52.0 mol% and 55.9 mol%, respectively), was much lower than that of any member of the genus Arenimonas. The predominant fatty acids (.8 %) were iso-C 16:0 , iso-C 15:0 , iso-C 14:0 , iso-C 17:1 v9c and C 16:1 v7c alcohol. Strain PYM3-14T contained Q-8 as the major ubiquinone and phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylmonomethylethanolamine as the major polar lipids. According to phenotypic and genotypic data strain PYM3-14 T represents a novel species of the genus Arenimonas, for which the name Arenimonas subflava sp. nov. is proposed. The type strain is PYM3-14 T (5NCAIM B 02508 T 5DSM 25526 T ). On the basis of new data obtained in this study, an emended description of the genus Arenimonas is also proposed.The drinking water supply of Budapest (Hungary) is based on the River Danube's riverbank filtration wells. These wells provide consumers with excellent quality water, which needs only safety chlorination before consumption. Microbial communities of drinking water can change significantly in the collecting and chlorinated distributing pipelines from the wells to the consumers . From the collecting system of the drinking water network of Budapest many bacterial strains have been isolated and characterized taxonomically (Homonnay et al., 2008;Tó th et al., 2011;Makk et al., 2011).On the basis of 16S rRNA gene sequence analysis, a novel yellowish-white-pigmented isolate from the drinking water network of Budapest belonged to the class Gammaproteobacteria, and its closest relatives were species of the genus Arenimonas. The genus Arenimonas has the following characteristics: aerobic, Gram-stain-negative, non-sporeforming, rod-shaped bacteria with Q-8 as the major isoprenoid quinone. The predominant cellular fatty acids are iso-C 16:0 , iso-C 15:0 and iso-C 17:1 v9c. The genus was reported to be unable to reduce nitrate and nitrite (Kwon et al., 2007). At the time of writing, the genus includes seven species with validly published names. The type species of the genus is Arenimonas donghaensis which was isolated from seashore sand in Pohang city, South Korea Abbreviations: MALDI-TOF, matrix-assisted laser-desorption/ionization time-of-flight; meso-DAP, meso-diaminopimelic acid.

“…Cyanobacterial blooming events in the Daechung Reservoir have been reported previously by Oh et al (2001, 2007) and Kim et al (2006). Similar to Arenimonas daechungensis CH15-1 T (Huy et al , 2013), strain CH15-11 T was isolated from sediment at a depth of 5 cm, aerobically grown on a R2A agar (Difco) plate at pH 7.0 and 15 °C and routinely subcultured under the same culture conditions. The optimal growth conditions, including the medium, temperature and pH were tested in triplicate using R2A (Difco), LB (Difco), NA (Difco) and TSA (Bacto) agar plates, temperatures at 4, 10, 15, 20, 28, 30, 37, 40 and 45 °C (during 2 weeks of incubation) and medium pH values from pH 4.0 to pH 10.0 in increments of 1 pH unit (during 3 days of incubation) were examined.…”

“…The highest and lowest values obtained for each sample were excluded and the remaining three values quoted as the DNA–DNA relatedness values. The 16S rRNA gene sequencing was performed as described by Huy et al (2013) using two universal primers 27F (5′-AGAGTTTGATCCTGGCTCAG-3′) and 1492R (5′-TACGGTTACCTTGTTACGACTT-3′) (Lane, 1991). The almost-complete 16S rRNA gene sequence of strain CH15-11 T comprised 1437 nt.…”

Strain CH15-11T , isolated from a sediment sample taken from Daechung Reservoir, SouthKorea, during the late-blooming period of cyanobacteria, was found to be a Gram-stain-negative, non-motile, non-spore-forming, rod-shaped and aerobic bacterium. Strain CH15-11 T grew optimally at pH 7 and 28-30 6C. According to a phylogenetic tree based on 16S rRNA gene sequences, strain CH15-11 T belonged to the genus Sphingomonas and clustered withSphingomonas sediminicola Dae 20 T , with which it shared the highest 16S rRNA gene sequence similarity (97.6 %). Chemotaxonomic analysis showed that strain CH15-11T had characteristics typical of members of the genus Sphingomonas, such as the presence of sphingoglycolipid, ubiquinone Q-10 and sym-homospermidine. Plus, strain CH15-11 T included summed feature 8 (C 18 : 1 v7c and/or C 18 : 1 v6c) and C 16 : 0 as the major fatty acids. The genomic DNA G+C content was 65.6 mol%. Sequence data showed that strain CH15-11 T was most closely related to Sphingomonas sediminicola Dae 20 T (97.6 %), Sphingomonas ginsengisoli Gsoil 634 T (97.2 %) and Sphingomonas jaspi TDMA-16 T (97.0 %). However, the DNA-DNA relatedness values between strain CH15-11 T and the most closely related type strains were within a range of 35-59 %. Thus, based on the phylogenetic, phenotypic and genetic data, strain CH15-11 T wasclassified as a member of the genus Sphingomonas as a representative of a novel species, for which the name Sphingomonas daechungensis sp. nov. is proposed. The type strain is CH15-11 T (5KCTC 23718 T 5JCM 17887 T ).The genus Sphingomonas was first proposed by Yabuuchi et al. (1990) and the genus description has been subsequently emended by Takeuchi et al. (2001), Yabuuchi et al. (2002 and Busse et al. (2003). A taxonomic study classified the genus as part of the family Sphingomonadaceae of the class Alphaproteobacteria. Based on the 16S rRNA gene sequences, polyamine patterns and polar lipid profiles, Takeuchi et al. (2001) proposed that the genus Sphingomonas should be divided into four genera, Sphingomonas, Novosphingobium, Sphingobium and Sphingopyxis. At the time of writing, the genus Sphingomonas consists of more than 60 species with validly published names. Members of the genus Sphingomonas are aerobic, rodshaped, Gram-reaction-negative, yellow-to orange-or redpigmented colonies and display the presence of 2-hydroxy fatty acids (C 14 : 0 2-OH) and the absence of 3-hydroxy fatty acids. The species of the genus also contain ubiquinone Q-10, sphingoglycolipid and homospermidine as the major respiratory quinone, polar lipid and polyamine, respectively. The present study reports on the taxonomic characterization of a Sphingomonas-like bacterial strain, CH15-11 T , which was isolated from a shoreline area, Chusori, of Daechung Reservoir in the central region of South Korea during the late-blooming period of cyanobacteria in summer. The isolated strain was identified using the EzTaxon-e database (http://eztaxon-e.ezbiocloud.et/; Kim et al., 2012) on the basis of 16S rRNA gene sequence data....
