Abstract A Gram-positive, non-motile, non-spore-forming and short rod-shaped actinomycete strain, designated GA224T, was isolated from an electronic waste associated bioaerosols. The isolate is facultatively anaerobic, which is able to grow at 25–40 ℃ (optimum 37 ℃) and pH 6.5–8.5 (optimum 8.0). The diamino acid in the cell wall of strain GA224T is 2,4-diaminobutyric acid (DAB), while major menaquinone is MK-12. The polar lipid profile is composed of diphosphatidylglycerol, phosphatidylglycerol, unidentified phospholipids, unidentified glycolipids and unidentified lipid. The major cellular fatty acid is anteiso-C15:0 and iso-C16:0. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain GA224T fell within the genus Yonghaparkia, the highest 16S rRNA gene sequence similarity values (98.60%) being obtained with respect to Yonghaparkia alkaliphile KSL-113T. The draft genome of strain GA224T comprised 2,495,189 bp with a G+C content of 72.17 mol%. The average nucleotide identity and digital DNA-DNA hybridization values between strain GA224T and phylogenetically related Yonghaparkia species were lower than 95% and 70%, respectively. Based on the phenotypic, chemotaxonomic and genomic data, strain GA224T represents a novel species, for which the name Yonghaparkia aerolata sp. nov. is proposed, with GA224T as the type strain (= GDMCC 1.2165T = JCM 34462T).

A novel actinomycete, strain KST3-10T, was isolated from sand sediment of a beach in Jeju, Korea, and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, translucent, apricot-coloured colonies comprising coccoid- or rod-shaped cells. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family Geodermatophilaceae and consistently formed a distinct sub-branch outside the radiation of the genus Blastococcus. The organism showed 16S rRNA gene sequence similarity values of 98.2 % with respect to Blastococcus aggregatus DSM 4725T and 98.1 % with respect to Blastococcus saxobsidens BC444T. The type strains of the two Blastococcus species shared 98.2 % sequence similarity with respect to each other, whereas the levels of sequence similarity between the novel organism and the type strains of the less closely related neighbours, Modestobacter multiseptatus and Geodermatophilus obscurus, were in the range 96.2–96.9 %. The physiological, biochemical and chemotaxonomic data revealed that the novel organism can be readily differentiated from members of the genus Blastococcus and that it merits separate species status. On the basis of the phenotypic and genotypic evidence, strain KST3-10T represents a novel species of the genus Blastococcus, for which the name Blastococcus jejuensis sp. nov. is proposed. The type strain is KST3-10T (=NRRL B-24440T=KCCM 42251T).

Emended Description

A Gram-staining-negative, non-flagellated, non-gliding and rod-shaped bacterial strain, designated HWR-17T, was isolated from seawater of the Yellow Sea in Korea. Strain HWR-17T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HWR-17T clustered with the two Mariniflexile species in the family Flavobacteriaceae, exhibiting 16S rRNA gene sequence similarity of 97.1–97.2 % to their type strains and less than 95.7 % sequence similarity to other members of the family Flavobacteriaceae. Strain HWR-17T contained MK-6 as the predominant menaquinone and iso-C15 : 0 as the major fatty acid. The polar lipid profile of strain HWR-17T contained phosphatidylethanolamine, an unidentified aminolipid and four unidentified lipids. The DNA G+C content of strain HWR-17T was 35.7 mol% and it exhibited 11 and 10 % DNA–DNA relatedness, respectively, with Mariniflexile gromovii KCTC 12570T and Mariniflexile fucanivorans DSM 18792T. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain HWR-17T is distinguishable from the two recognized Mariniflexile species. On the basis of the data presented, strain HWR-17T is considered to represent a novel species of the genus Mariniflexile, for which the name Mariniflexile aquimaris sp. nov. is proposed. The type strain is HWR-17T ( = KCTC 23346T  = CCUG 60529T). An emended description of the genus Mariniflexile is also proposed.

A Gram-positive, non-motile, spherical, non-spore-forming bacterial strain, DS-52T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. It grew optimally at 25 °C and pH 6.0–7.0. Strain DS-52T had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and galactose, mannose, xylose and rhamnose as whole-cell sugars. It contained MK-8(H4) and MK-9(H4) as the predominant menaquinones and anteiso-C15 : 0, iso-C15 : 0 and C17 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyldimethylethanolamine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-52T is most closely related to the genus Nakamurella of the suborder Frankineae. Strain DS-52T exhibited 16S rRNA gene sequence similarity values of 96.5 % to Nakamurella multipartita JCM 9543T and 92.0–93.9 % to other members of the suborder Frankineae. The diagnostic diamino acid type and polar lipid profile of strain DS-52T were the same as those of the genus Nakamurella. However, strain DS-52T could be clearly distinguished from the genus Nakamurella by differences in predominant menaquinones, major fatty acids and cell-wall sugars. Accordingly, based on combined phenotypic, chemotaxonomic and phylogenetic data, strain DS-52T (=KCTC 19127T=CIP 108919T) is proposed as the type strain of a novel species in a new genus, Humicoccus flavidus gen. nov., sp. nov.
