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).

A Gram-stain-negative, aerobic, asporogenous, motile by gliding, dull-yellow, long rod-shaped bacterial strain, designated SNL9T, was isolated from a flooded paddy field near Dongguk University, Republic of Korea. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that SNL9T represents a member of the genus Flavobacterium and is most closely related to Flavobacterium ummariense DS-12T (96.2%) and Flavobacterium viscosum YIM 102796T (96.3%). The average nucleotide identity and in silico DNA–DNA hybridization (DDH) values with F. ummariense DS-12T and F. viscosum YIM 102796T were 89.3/39.1 and 87.1/33 %, respectively. The major fatty acids of SNL9T were identified as iso-C15 : 0, summed feature 3 (comprising C16  :  1ω6c and/or C16  :  1ω7c) and summed feature 9 (comprising iso-C17 : 1ω9c and/or 10 methyl C16 : 0). SNL9T contained MK-6 as the major respiratory quinone. The polar lipids were phoshatidylethanolamine, one unidentified aminophosphoglycolipid, three unidentified aminoglycolipids, two unidentified glycolipids and one unidentified phosphoglycolipid. The DNA G+C content was 34.2 mol%. SNL9T produces carotenoid and flexirubin-type pigments. Among them, carotenoids are particularly valuable for the biotechnological and pharmaceutical industries due to their antioxidant activity. Aryl polyenes (APE) pigments were also found in SNL9T which are responsible for yellow pigment in bacteria. They are stored in the bacterial membrane and protect the bacteria from oxidative stress, particularly from reactive oxygen species. In this paper, we describe a novel isolate, SNL9T, which protect itself from the attack of free radicals using specific natural products in the membrane. Because of their anti-oxidation properties, aryl polyenes may also be of interest to the cosmetic industry. On the basis of the results of phenotypic, genotypic and chemotaxonomic analyses, SNL9T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium baculatum sp. nov. is proposed. The type is SNL9T (=KACC 21170T=NBRC 113746T).

Two Gram-stain-negative, non-motile, rod-shaped bacterial strains were isolated from the surfaces of rice roots. They were designated as strains 1303T and 1310. Their colonies were circular, entire, opaque, convex and yellow. They were chitinase- and catalase-positive, reduced nitrate and grew at 16–37 °C (optimum, 30 °C), pH 5.0–10.0 (optimum, pH 7.0) and 0–2.0% NaCl (optimum, 1.0 %). Based on the 16S rRNA gene sequence analysis, they were classified as members of the genus Chitinophaga . Results of phylogenetic and phylogenomic analyses indicated that they formed a cluster with Chitinophaga eiseniae YC6729T, Chitinophaga qingshengii JN246T, Chitinophaga varians 10-7 W-9003T and Chitinophaga fulva G-6-1-13T. When the genomic sequences of strains 1303T and 1310 were compared with their close relatives, the average nucleotide identity and digital DNA–DNA hybridization values were below the cut-off levels. Phosphatidylethanolamine was the major polar lipid. MK-7 was the major respiratory quinone. iso-C15 : 0, C16 : 1  ω5c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c) were the predominant fatty acids. Differential characteristics between both strains and their close relatives were also observed. Based on the distinctions in genotypic, phenotypic and chemotypic features, strains 1303T and 1310 represent members of a novel species of the genus Chitinophaga , for which the name Chitinophaga oryzae sp. nov. is proposed. The type strain is 1303T (=KACC 22075T=TBRC 12926T).
