AIMS The aim of this study was to identify and characterize a compound produced by the plant growth promoting bacterium, Bacillus thuringiensis non-Bradyrhizobium Endophytic Bacterium 17. METHODS AND RESULTS The bacterial peptide was analysed and purified via HPLC. Using the disk diffusion assay this peptide inhibited the growth of 16/19 B. thuringiensis(More)
The mechanisms by which many plant growth promoting rhizobacteria (PGPR) affect plants are unknown. We recently isolated a rhizosphere bacterium (Bacillus thuringiensis NEB17), that promotes soybean growth and screened the liquid growth medium in which it grew for plant growth stimulating materials. We have also shown that it produces a bacteriocin (named(More)
Soil salinity is one of the most severe factors limiting nodulation, yield and physiological response in soybean. The possible role of plant growth promoting rhizobacteria (PGPR) in restricting mineral nutrients and thus alleviating soil salinity stress during plant growth has not yet been established. In this study, the beneficial effects of inoculation(More)
This study aimed to describe the diversity of antifungal lactic acid bacteria (LAB) in popular traditional Korean fermented food. A total of 22 LAB strains was selected and subjected to a monophasic identical approach using 16S rRNA gene sequence analysis. Antifungal LAB associated with fermented food was identified as Lactobacillus plantarum (9),(More)
Folic acid-decorated self-organized nanoparticles were fabricated to target folate receptor of cancer cells. Doxorubicin (DOX) was conjugated with carboxyl group of dextran backbone using succinic anhydride (DexSU-DOX). DOX-loaded self-organized nanoparticles were prepared by complexation with folic acid-grafted chitosan (ChitoFA) and DexSU-DOX.(More)
BACKGROUND Ganghwaljetongyeum (GHJTY), a complex herbal decoction, is used to treat rheumatoid arthritis. However, the action mechanism of GHJTY is not still unclear on rheumatoid arthritis. In this study, we examined the beneficial effects and the action mechanisms of GHJTY on synoviocyte proliferation and inflammatory mediators. METHODS To test the(More)
We performed angle-resolved photoemission (ARPES) experiments with circularly polarized light and first-principles density functional calculation with spin-orbit coupling to study surface states of a topological insulator Bi2Se3. We observed circular dichroism (CD) as large as 30% in the ARPES data with upper and lower Dirac cones showing opposite signs in(More)
The "evolution" of a thing, a custom, an organ is thus by no means its progressus toward a goal, even less a logical progressus by the shortest route and with the least expenditure of force, but a succession of more or less profound, mutually independent processes of subduing, plus the resistances they encounter, the attempts at transformation for the(More)
Graphene quantum dot (GQD) layers were deposited as an energy-down-shift layer on crystalline-silicon solar cell surfaces by kinetic spraying of GQD suspensions. A supersonic air jet was used to accelerate the GQDs onto the surfaces. Here, we report the coating results on a silicon substrate and the GQDs' application as an energy-down-shift layer in(More)
Inoculation with rhizobia or application of Nod factors (lipo-chitooligosaccharides, LCOs) causes transient increases in cytosolic calcium concentration in root hairs of legume plants. We conducted experiments to evaluate whether application of LCO and inoculation with rhizobia improved (45)CaCl(2) uptake into soybean (Glycine max [L.] Merr.) leaves. Roots(More)
