A bacterial pathogen, Pseudomonas syringae pv. actinidiae (Psa), is a causal agent of kiwifruit bacterial canker worldwide. Psa biovar 3 (Psa3) was first detected in 2011 at an orchard in Dodeok-myeon, Goheunggun, Jeonnam Province in Korea. In this study, we present the results of an epidemiological study regarding Psa3 occurrence on kiwifruit orchards in(More)
A rod-shaped, yellow-pigmented, aerobic, Gram-negative bacterium, designated strain JO-1(T), was isolated from an apparently healthy Pacific oyster, Crassostrea gigas, collected at Wan Island, Korea. It grew at 15-37 degrees C (optimum 30 degrees C) only in the presence of sea salts. Strain JO-1(T) hydrolysed casein, Tween 80 and starch. The major fatty(More)
With the emergence and growing complexity of bacterial drug resistance, rapid and reliable susceptibility testing has become a topical issue. Therefore, new technologies that assist in predicting the effectiveness of empiric antibiotic therapy are of great interest. Although the use of matrix-assisted laser desorption/ionisation time-of-flight mass(More)
A strictly aerobic, orange-pigmented and Gram-staining-negative bacterium, designated K17-16(T), was isolated from seawater of Gangjin Bay, Korea. Comparative 16S rRNA gene sequence analysis revealed that strain K17-16(T) was a member of the genus Polaribacter in the family Flavobacteriaceae and showed 94.0-95.6 % sequence similarity with the type strains(More)
A novel Gram-negative, aerobic, orange-pigmented bacterial strain, designated K7-2(T), was isolated from seawater of Gangjin Bay, Korea, and subjected to a polyphasic taxonomic study. Strain K7-2(T) contained ubiquinone-10 (Q-10) as the predominant respiratory lipoquinone and did not produce bacteriochlorophyll a. Major fatty acids were C(18 : 1)omega7c(More)
An aerobic, gliding, yellow-pigmented bacterium lacking flagella and showing strong tyrosinase activity, designated strain EM41(T), was isolated from seawater on the eastern coast of Jeju Island in Korea. Growth was observed at 15-35 degrees C (optimum, 25-30 degrees C) and at pH 6.5-9.0 (optimum, pH 7.0-8.5). Cells were Gram-negative, negative for(More)
At present, acetylcholinesterase (AChE) inhibitors are the first group of drugs to treat mild to moderate Alzheimer's disease (AD). Although beneficial in improving cognitive and behavioral symptoms, the effectiveness of AChE inhibitors has been questioned since they do not delay or prevent neurodegeneration in AD patients. Therefore, in the present study,(More)
A novel strictly aerobic, orange-pigmented, Gram-stain-negative bacterium, designated strain GJ16(T), was isolated from coastal seawater of Gangjin Bay, the southernmost part of the Korean peninsula, and subjected to a polyphasic taxonomic study. It grew optimally at 25-30 °C, at pH 7.0-8.0 and in the presence of 3 % NaCl. Comparative 16S rRNA gene sequence(More)
An aerobic, pale-orange-pigmented, Gram-stain-negative bacterium, designated strain EM39T, was isolated from seawater from the eastern coast of Jeju Island, Korea, and its taxonomic status was established using a polyphasic approach. Comparative 16S rRNA gene sequence studies revealed that strain EM39T formed a distinct lineage within the family(More)
Antioxidant properties of 46 lichen species collected from high-UV exposed alpine areas of southwestern China were evaluated for their therapeutic utilization. Anti-linoleic acid peroxidation activity, 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging activity, reducing power and the total phenolic contents were assessed in methanol extract of the lichens(More)
