A novel actinobacterium, designated strain JXJ CY 01(T), was isolated from a mucilaginous sheath of Microcystis aeruginosa FACHB-905 collected from Lake Dianchi, south-west China. Taxonomic position of the isolate was determined by polyphasic approaches. Strain JXJ CY 01(T) shared 16S rRNA sequence similarities of 98.9 and 98.0% with Microbacterium marinilacus YM11-607(T) and Microbacterium paludicola US15(T), and less than 98% with other members of the genus Microbacterium. The DNA-DNA relatedness values between strains JXJ CY 01(T) and M...

A polyphasic taxonomic study was carried out on strain EBR-8-1(T) isolated from a biofilm reactor in Korea. The cells of the strain were Gram-stain negative, non-spore-forming, non-motile, and short rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of this strain with Betaproteobacteria, which showed high pairwise sequence similarities with Pusillimonas noertemannii BN9(T) (99.1 %), Pusillimonas soli MJ07(T) (97.3 %), Pusillimonas ginsengisoli DCY25(T) (97.2 %), and Pusillimonas harenae B201(T) (96...

A novel member of the Acidobacteria was isolated from a microbial mat growing on a geothermally-heated dead tree trunk in Hawai'i Volcanoes National Park (Hawai`i, USA). The rod-shaped, Gram-negative capsulated cells of strain PMMR2T were non-motile, and catalase and oxidase negative. Growth occurred aerobically from 15 oC - 55 oC (optimum 40 oC), and at pH values from 4.5 - 7.0 (optimum 6.5). A limited range of sugars and organic acids supported growth. However, results of a genomic analysis suggested that various polysaccharides might be hydrolyzed as carbon sources, and evidence for pectin degradation was observed in liquid cultures...

OBJECTIVE The aims of this study were to determine if the morphological and functional changes induced by neural stem cell (NSC) grafts after transplantation into the rodent spinal cord can be detected using MR diffusion tensor imaging (DTI) and, furthermore, if the DTI-derived mean diffusivity (MD) metric could be a biomarker for cell transplantation in spinal cord injury (SCI). METHODS A spinal contusion was produced at the T-8 vertebral level in 40 Sprague Dawley rats that were separated into 4 groups, including a sham group (injury without NSC injection), NSC control group (injury with saline injection), co-injection control group (injury with Prograf), and the experimental group (injury with NSC and Prograf injection)...

Strain CHO1(T) was observed to form yellow colonies on R2A agar medium. The cell wall peptidoglycan was found to contain alanine, glycine, glutamic acid, D-ornithine and serine. The cell wall sugars were identified as galactose, mannose, rhamnose and ribose. Strain CHO1(T) was found to contain MK-11, MK-12, MK-13 as the predominant menaquinones and anteiso-C15:0, iso-C16:0, and anteiso-C17:0 as the major fatty acids...

During brain development, radial glial (RG) cells and the different progenitor subtypes are characterized by their bipolar morphology that includes an ovoid cell body and one or two radial processes that span across the developing cerebral wall. Different cells transport the reduced form of vitamin C, ascorbic acid (AA), using sodium-dependent ascorbic acid cotransporters (SVCT1 or SVCT2). SVCT2 is mainly expressed in the nervous system (CNS); however, its localization in the central nervous system during embryonic development along with the mechanism by which RG take up vitamin C and its intracellular effects is unknown...

Strain Eup-16T, isolated from a torch coral Euphyllia glabrescens, was characterized using a polyphasic taxonomy approach. Cells of strain Eup-16T were Gram-staining-negative, aerobic, motile by means of a single polar flagellum, poly--hydroxybutyrate-containing, rod-shaped and forming pale yellow colonies. Optimal growth occurred at 25-30 °C, pH 7.5-9, and in the presence of 1 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Eup-16T belonged to the genus Thalassotalea and was most closely related to Thalassotalea montiporae CL-22T with sequence similarity of 98...

Because the plant cell wall provides the first line of defence against biotic and abiotic assaults, its functional integrity needs to be maintained under stress conditions. Through a phenotype-based compound screening approach we identified a novel cellulose synthase inhibitor, designated C17. C17 administration depletes cellulose synthase complexes (CSCs) from the plasma membrane in Arabidopsis thaliana, resulting in anisotropic cell elongation and a weak cell wall. Surprisingly, in addition to mutations in CELLULOSE SYNTHASE 1 (CESA1) and CELLULOSE SYNTHASE 3 (CESA3), a forward genetic screen identified two independent defective genes encoding pentatricopeptide repeat (PPR)-like proteins [CELL WALL MAINTAINER 1 (CWM1) and 2 (CWM2)] as conferring tolerance to C17...

A novel Gram-stain-negative, facultatively anaerobic, filamentous, and yellowish-white-pigmented marine bacterium, designated strain FB208T, was isolated from marine sediment obtained off the coastal area of Weihai, China. Cells of FB208T were filamentous during exponential growth, fragmented to rods in the stationary growth phase, and became spherical in aged cultures. Strains grew optimally at 33°C, in pH 7.0-7.5, and in the presence of 2.0-3.0% (w/v) NaCl.
