The 16S Rrna Gene

A novel Gram-stain-positive, white-pigmented, non-motile, non-sporulating, catalase- and oxidase-positive, strictly aerobic coccus, designated strain ZXM223T, was isolated from a seawater sample collected from the coast of Qingdao, PR China, during a green algal bloom. It grew at pH 6.0–10.5 and 0–25.0 % (w/v) NaCl, with optimum growth at pH 8.5 and 3.0 % (w/v) NaCl. Growth occurred at 16–42 °C (optimum at 28 °C). The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. Menaquinone 6 (MK-6) was the major respiratory quinone. The polar lipids were phosphatidylglycerol, three unidentified phospholipids and two unknown glycolipids. The peptidoglycan type was l-Lys–Gly5–6. The genomic DNA G+C content was 43.5 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain ZXM223T within the genus Salinicoccus, with sequence similarity of 92.2–97.1 % between ZXM223T and the type strains of this genus. The closest relatives were Salinicoccus kunmingensis YIM Y15T, ‘S. salitudinis’ YIM-C678 and S. alkaliphilus T8T. The DNA–DNA relatedness between strain ZXM223T and S. kunmingensis CGMCC 1.6302T and ‘S. salitudinis’ CGMCC 1.6299 ( = YIM-C678) was 37±3 and 30±2 %, respectively. The phenotypic, chemotaxonomic and phylogenetic characteristics and low DNA–DNA relatedness support the proposal of a novel species of the genus Salinicoccus, Salinicoccus qingdaonensis sp. nov., with the type strain ZXM223T ( = LMG 24855T  = CGMCC 1.8895T).

A myxobacterial strain, designated SYR-2T, was obtained from a mud sample from an estuarine marsh alongside the Yoshino River, Shikoku, Japan. It had rod-shaped vegetative cells and formed bacteriolytic enlarging colonies or so-called ‘swarms’ in the agar media. Fruiting-body-like globular to polyhedral cell aggregates and myxospore-like spherical to ellipsoidal cells within them were observed. Those features coincided with the general characteristics of myxobacteria. The strain was mesophilic and strictly aerobic. Growth of SYR-2T was observed at 18–40 °C (optimum, 30–35 °C), pH 5.5–8.3 (optimum, pH 7.0–7.5) and with 0.0–2.5 % (w/v) NaCl (optimum, 0.2–1.0 %). Both Mg2+ and Ca2+ were essential cations for the growth. The predominant fatty acids were iso-C15 : 0 (43.8 %), iso-C17 : 0 (22.4 %) and iso-C16 : 0 (9.6 %). A C20 : 4 fatty acid [arachidonic acid (4.3 %)], iso-C19 : 0 (1.5 %) and anteiso-acids [ai-C15 : 0 (0.5 %), ai-C17 : 0 (0.3 %)] were also detected. The G+C content of the DNA was 69.7 mol%. The strain contained menaquinone-7 (MK-7) as the major respiratory quinone. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SYR-2T belonged to the suborder Nannocystineae , order Myxococcales in the class Deltaproteobacteria , and the strain was most closely related to two type strains of marine myxobacteria, Enhygromyxa salina SHK-1T and Plesiocystis pacifica SIR-1T, with 96.5 % and 96.0 % similarities, respectively. These characteristics determined in this polyphasic study suggested that strain SYR-2T represents a novel species in a new genus of myxobacteria. The name Pseudenhygromyxa salsuginis gen. nov., sp. nov. is proposed to accommodate this isolate, and the type strain of Pseudenhygromyxa salsuginis is SYR-2T ( = NBRC 104351T = DSM 21377T).
