gen. nov., sp. nov., a new member of the family isolated from a cave soil.

A novel Gram-stain-positive, actinobacterial strain, designated C5-26, was isolated from soil from a natural cave in Jeju, Republic of Korea, and its taxonomic position was investigated using a polyphasic approach. The organism was aerobic, and cells were non-spore-forming, non-motile cocci that occurred singly, in pairs, in triplets, in tetrads, in short chains or in irregular clusters. Colonies of the cells were circular, convex, entire and white.

Melaminivora jejuensis sp. nov., isolated from Swinery waste.

A sulfur-oxidizing bacterium, designated strain KBB12, was isolated from swinery waste collected in Jeju, Republic of Korea. The cells were Gram-stain-negative, flagellated and rod-shaped. Growth occurred at 15-45 °C (optimum, 30-37 °C), at pH 6-9 (optimum, pH 7.

Correlation between species-specific metabolite profiles and bioactivities of blueberries (Vaccinium spp.).

Metabolite profiling of three blueberry species (Vaccinium bracteatum Thunb., V. oldhamii Miquel.

Inhibition of nitric oxide production in lipopolysaccharide-activated RAW 264.7 macrophages by Jeju plant extracts.

Nitric oxide (NO) produced in large amounts by inducible nitric oxide synthase (iNOS) is known to be responsible for the vasodilation and hypotension observed during septic shock and inflammation. Thus, inhibitors of iNOS may be useful candidates for the treatment of inflammatory diseases accompanied by the overproduction of NO. In this study, we prepared alcoholic extracts of Jeju plants and screened them for their inhibitory activity against NO production in lipopolysaccharide (LPS)-activated macrophages.

Chemical composition, antioxidant, anti-elastase, and anti-inflammatory activities of Illicium anisatum essential oil.

The essential oil of air-dried Illicium anisatum (Illiciaceae), obtained by hydrodistillation was analyzed by gas chromatography-mass spectrometry (GC-MS). Fifty-two components were identified in the essential oil and the main component was eucalyptol (21.8 %).
