A novel slow-growing bacterial strain designated as AW305T was isolated from an agricultural floodplain soil located in Mashare, Kavango region, Namibia. Cells stained Gram-negative, were non-motile, non-spore-forming, coccoid to rod-shaped and did not form a capsule. Colonies were yellow-pigmented, but flexirubin-type pigments were not detected. AW305T had an aerobic chemo-organoheterotrophic metabolism, using a narrow spectrum of carbon sources for growth, with preference for complex protein substrates, organic acids and amino acids...

A novel Gram-stain-negative, facultatively anaerobic, yellowish and agar-digesting marine bacterium, designated strain QM50T, was isolated from coastal seawater in an aquaculture site near Qingdao, China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate represented a member of the genus Colwellia and exhibited the highest sequence similarity (97.4 %) to Colwellia aestuarii SMK-10T. Average nucleotide identity (ANI) values based on draft genome sequences between strain QM50T and C...

Phylogenetic analyses were performed for members of the family Chromatiaceae, signature nucleotides deduced and the genus Alishewanella transferred to Chromatiaceae. Phylogenetic analyses were executed for the genera Alishewanella, Arsukibacterium and Rheinheimera and the genus Rheinheimera is proposed to be split, with the creation of the Pararheinheimera gen. nov. Furthermore, the species Rheinheimera longhuensis, is transferred to the genus Alishewanella as Alishewanella longhuensis comb. nov. Besides, the genera Alishewanella and Rheinheimera are also emended...

Vlasouliolides A-D (1-4), four rare sesquiterpene lactone dimers, were isolated from Vladimiria souliei. The common structural characteristic of 1-4 is the C32 skeleton comprising two sesquiterpene lactone units linked by a C11-C13' single bond with one acetyl connected to the C-13 position of one of the two sesquiterpene lactone units. The stereochemistries of 1-4 were assigned by a combination of NOESY correlations and Cu-Κα X-ray crystallographic analyses. Compounds 1-4 strongly inhibited the production of NO in LPS-stimulated RAW 264...

The entomopathogen "Corynebacterium okanaganae" was described by Lüthy in 1974 but the name was never validly published. Phylogenetic analysis employing 16S rRNA gene sequences demonstrate that "Corynebacterium okanaganae" is not a member of the genus Corynebacterium but related to members of the Microbacteriaceae being most closely related to, but distinct from, members of the genera Rathayibacter, Mycetocola and Curtobacterium. The bacterium is an aerobic, Gram-positive staining, rod-shaped actinobacterium with the cell-wall peptidoglycan based on 2,4, diaminobutyric acid as the diagnostic diamino acid...

A Gram-positive, aerobic, non-motile actinomycete (strain MS 3/20(T)) was isolated from the sediment of the Sundarbans mangrove forest in India. On International Streptomyces Project (ISP) medium 2, the isolate produced yellowish brown to red aerial hyphae that carried spiny-surfaced spores in a retinaculum-apertum arrangement. Whole-cell hydrolysate of the strain contained LL-diaminopimelic acid and galactose. Predominant menaquinones were MK-9(H8) and MK-9(H6). Diagnostic polar lipids were glycolipid, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, unidentified phospholipid and unidentified amino lipid...

The taxonomic position of actinomycete, strain NR4-ASC07T isolated from soil sample collected from Sirindhorn peat swamp forest, Narathiwat Province, Thailand, was clarified using a polyphasic approach. On the basis of morphological and chemotaxonomic characteristics, it was classified in the members of the genus Nonomuraea. It produced tightly closed spiral spore chains on aerial mycelium as well as forming the pseudosporangium. Whole-cell hydrolysate contained meso-diaminopimelic acid, glucose, ribose, madurose and mannose...

White and pale yellow coloured bacteria were isolated from the riverside soil, Daejeon, South Korea, and were designated UCM-11(T), UCM-F25, and UCM-80(T). We found that all strains were able to reduce nitrate, and the cells were aerobic and motile. The DNA G+C contents of UCM-11(T), UCM-F25, and UCM-80(T) were between 68.9 to 71.2 mol% and the main ubiquinone was observed as Q-8. Based on16S rRNA gene sequences, strains UCM-11(T) and UCM-F25 were found to closely match with Azohydromonas australica IAM 12664(T) (98...

Ascorbic acid (AA) is a known antioxidant that participates in a wide range of processes, including stem cell differentiation. It enters the cell through the sodium-ascorbate co-transporter SVCT2, which is mainly expressed by neurons in the adult brain. Here, we have characterized SVCT2 expression in the postnatal cerebellum in situ, a model used for studying neurogenesis, and have identified its expression in granular precursor cells and mature neurons. We have also detected SVCT2 expression in the cerebellar cell line C17...
