During the past times, occurrence of macro alga Ulva lactuca on coastal areas Jeju Island, Korea, has resulted in expansion devastating green tides, thus affecting sustainability, aesthetic appearances, and tourism activities. Taking consideration above scenario, substantial economic costs are required for environmental protection island, it is highly recommended to employ an alternative useful way. Hence, this paper proposes a new strategy utilize as tribopositive layer triboelectric...
Abstract Symphyocladia lithophila sp. nov. is newly described using both morphological and molecular analyses of samples collected from the southeastern coast Korea. The new species characterized by small size, ecorticate thallus, with 8–10 pericentral cells, lacking trichoblasts, having 5–7 segments congenital fusions. S. was observed to be a winter species, producing tetrasporangia December February. Plastid-encoded rbc L sequences were determined in four different locations 21 putative...
ABSTRACT Hypnea is an economically and ecologically important red alga including about 53 species worldwide. Here, we describe H. asiatica sp. nov. from Korea, Japan, Taiwan. Specimens of this the northwestern Pacific have often been assigned to charoides. distinguished by percurrent main axes, branches with abruptly curved adaxial branchlets, presence lenticular thickening in walls medullary cells. It abundant wave‐exposed sites summer through fall produces tetrasporangial sori fall. We...
• Immunomodulatory effect of SHE on murine splenocytes. suppresses cytokines release in Con A stimulated stimulates the proliferation The health benefit brown seaweeds has been proclaimed for centuries, particularly Asian countries. seaweed Sargassum horneri suggested to have immune-boosting and anti-inflammatory/immune-regulatory effects, but their mechanism is still elusive. This study researches immunological 70% ethanol extract S. (SHE) unstimulated A-stimulated When treated alone, had...
Flumequine is a well-known second generation quinolone antibiotic that induces phototoxicity. However, the effect of flumequine on skin melanogenesis unclear. Therefore, we, for first time, investigated whether regulates melanogenesis. The present study showed slightly inhibited in vitro mushroom tyrosinase activity but significantly increased extracellular and intracellular melanin content B16F10 cells promoted expression microphthalmia-associated transcription factor (MITF) tyrosinase....
Abstract Background DNA barcoding is becoming a widely applied tool for the quick and accurate identification of species. The evolution mitochondrial cytochrome c oxidase subunit I (COI) gene sufficiently rapid to allow discrimination between closely related species biogeographic subgroups within Gracilaria salicornia was originally described as being from Manila, Philippines, distributed throughout Asia Indian Ocean. To more accurately define this its genetic diversity owing confusion...
Abstract Chondracanthus teedei and C. chamissoi are regarded as cosmopolitan endemic species, respectively. To verify the geographic distribution of these two we analyzed specimens from Western Pacific Atlantic coast Spain, well Chile using plastid rbc L mitochondrial COI genes. The phylogenetic tree revealed that “ ” Asia sp. France conspecific with Chile, but distinct clade Atlantic. These results indicate is not exclusively distributed in southeastern Pacific, also found Korea/Japan...
Several species classified to the genus Ulva are primarily responsible for causing green tides all over world. For almost two decades, have been resulted in numerous ecological problems along eastern coast of Jeju Island, Korea. In order characterize massive blooms on we conducted DNA barcoding tufA and rbcL sequences 183 specimens from eight sites Island. The concatenated analysis identified five bloom-forming species: U. australis, lactuca, laetevirens, ohnoi a novel species, pseudo-ohnoi...
SUMMARY Vegetative and reproductive development of Neosiphonia flavimarina gen. et sp. nov. (Rhodomelaceae, Ceramiales) from Bangpo on the western coast Korea was investigated. This species is superficially similar to Polysiphonia, but differs distinctly latter in vegetative structures. The plants attach by a solid disk composed dense cluster rhizoids cut off pericentral cell wall, bear erect indeterminate branches producing lateral-branch initials successive segments spiral arrangement....
Morphological and molecular studies were carried out on two Polysiphonia with 6–9 pericentral cells from the Atlantic Iberian Peninsula. A detailed description is provided for P. foetidissima, a poorly known species originally described UK that widespread abundant in schneideri, U.S.A. Bermuda, reported first time Europe (Southern Spain). It was collected attached to man-made structures such as floating docks artificial substrata aquaculture believed be newly introduced Europe. In addition,...
Six species of the genus Symphyocladia are currently recognized worldwide, all which reported to grow on Korean coast. We described a new glabra sp. nov. based morphological and molecular evidence. The is characterized by mostly an erect broad thallus, parallel arrangement numerous apical cells, completely fused congenital corticated basal portion faint midrib with six eight pericentral rhizoids cutting off from absent vegetative trichoblasts. has similarity S. marchantioides jejuinsula....
During the last decade, demand for natural gas has steadily increased prevention of environmental pollution. For this reason, many liquefied (LNG) carriers have been manufactured. Since one most important issues in design LNG is to guarantee structural safety, use low-temperature materials increasing. Among commonly employed materials, nickel steel benefits such as good strength and outstanding corrosion resistance. Accordingly, steels are used storage tanks. However, study fracture...
Located in the heart of South Pacific Ocean, French Polynesian islands represent a remarkable setting for biological colonization and diversification, because their isolation. Our knowledge this region's biodiversity is nevertheless still incomplete many groups organisms. In late 1990s 2000s, series publications provided first checklists marine algae, including Chlorophyta, Rhodophyta, Ochrophyta, Cyanobacteria, established mostly on traditional morphology-based taxonomy. We initiated...
