Two Gram-stain-positive, facultatively anaerobic, motile, aerobic, rod-shaped and non-spore-forming actinobacteria, strains AO-9T and AO-18, were isolated from paddy soil collected from Daejeon, Republic of Korea. Colonies were smooth, lemon-yellow and circular and 0.5–0.8×2.0–2.4 µm in diameter after 3 days of incubation at 28 °C on tryptic soy agar. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains AO-9T and AO-18 belonged to the genus Cellulomonas , showing the highest sequence similarities to Cellulomonas marina FXJ8.089T (96.6 %), Cellulomonas endophytica SYSUP0004T (96.5 %), Cellulomonas gelida DSM 20111T (96.2 %), Cellulomonas uda DSM 20107T (96.1 %), Cellulomonas rhizosphaerae NEAU-TCZ24T (96.1 %), Cellulomonas composti TR7-06T (96.0 %), Cellulomonas persica JCM 18111T (96.0 %) and less than 96 % to other closely related species. The DNA–DNA hybridization values between strains AO-9T and AO-18 were 87 %. The average nucleotide identity and digital DNA–DNA hybridization values between strain AO-9T and type strains of related species of the genus Cellulomonas were 84.0–85.8 % and 20.3–20.9 %, respectively. The major cellular fatty acids are anteiso-C15:0 (49.9 %), C14:0 (12.9 %) and iso-C14:0 (12.1 %). The predominant isoprenoid quinone was MK-9 (H4). The polar lipid profile consists of diphosphatidylglycerol, phosphatidylglycerol and one unidentified lipid. The DNA G+C content was 72.9 mol%. Based on its distinctive phenotypic, phylogenetic and chemotaxonomic characteristics, the two strains are considered to represent novel species of the genus Cellulomonas , for which the name Cellulomonas citrea sp. nov. is proposed. The type strain is AO-9T (=KACC 19069T=NBRC 112523T).

Taxonomic Approach

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

A Gram-staining-positive, heterotrophic, aerobic, non-motile, non-endospore-forming, yellow-coloured rod, designated strain N5T, was isolated from a soil sample collected at an industrial waste site in Noida, on the outskirts of Delhi, India. In phylogenetic analyses based on 16S rRNA gene sequences, strain N5T was most closely related to members of established species in the genus Microbacterium (with sequence similarities of approximately 94.0–97.6 %), particularly Microbacterium indicum LMG 23459T (97.59 %) and Microbacterium gubbeenense LMG 19263T (97.18 %). In DNA–DNA hybridization studies, however, none of the DNA–DNA relatedness values between strain N5T and members of the genus Microbacterium exceeded 11.3 %. The genomic DNA G+C content of the novel strain was 68 mol%. The chemotaxonomic characteristics of strain N5T, which had MK-11 and MK-10 as its major menaquinones and anteiso-C15 : 0 (45 %), anteiso-C17 : 0 (37 %), iso-C16 : 0 (8.5 %) and C16 : 0 (4.5 %) as its predominant fatty acids, were consistent with classification in the genus Microbacterium . Peptidoglycan in the novel strain, which contained ornithine, alanine, glycine, homoserine, glutamic acid, 3-hydroxyglutamic acid, muramic acid and traces of N-glycolyl residues, was of type B2β. The polar lipid profile of strain N5T comprised diphosphatidylglycerol, phosphatidylglycerol and an unknown glycolipid. The novel strain’s major cell-wall sugars were glucose and galactose. Based on the phylogenetic, DNA–DNA hybridization, chemotaxonomic and phenotypic data, strain N5T represents a novel species within the genus Microbacterium for which the name Microbacterium amylolyticum sp. nov. is proposed; the type strain is N5T ( = DSM 24221T = CCM 7881T).

A Gram-negative, rod-shaped and motile bacterial isolate, designated strain NS9T, isolated from air of the Sainsbury Centre for Visual Arts in Norwich, UK, was subjected to a polyphasic taxonomic study including phylogenetic analyses based on partial 16S rRNA, gyrB and lepA gene sequences and phenotypic characterization. The 16S rRNA gene sequence of NS9T identified Massilia haematophila CCUG 38318T, M. niastensis 5516S-1T (both 97.7 % similarity), M. aerilata 5516S-11T (97.4 %) and M. tieshanensis TS3T (97.4 %) as the next closest relatives. In partial gyrB and lepA sequences, NS9T shared the highest similarities with M. haematophila CCUG 38318T (94.5 %) and M. aerilata 5516-11T (94.3 %), respectively. These sequence data demonstrate the affiliation of NS9T to the genus Massilia . The detection of the predominant ubiquinone Q-8, a polar lipid profile consisting of the major compounds diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol and a polyamine pattern containing 2-hydroxyputrescine and putrescine were in agreement with the assignment of strain NS9T to the genus Massilia . Major fatty acids were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0, C18 : 1ω7c and C10 : 0 3-OH. Dissimilarities in partial lepA and gyrB gene sequences as well as results from DNA–DNA hybridizations demonstrate that strain NS9T is a representative of an as-yet undescribed species of the genus Massilia that is also distinguished from its close relatives based on physiological and biochemical traits. Hence, we describe a novel species, for which we propose the name Massilia norwichensis sp. nov., with the type strain NS9T ( = CCUG 65457T = LMG 28164T).
