Endozoicomonas atrinae sp. nov., isolated from the intestine of a comb pen shell Atrina pectinata.
A novel bacterium, designated strain WP70(T), was isolated from the gut of a comb pen shell (Atrina pectinata) collected from the southern sea of Yeosu in Korea. The isolate was Gram-stain-negative, aerobic, non-motile and rod-shaped. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain WP70(T) belonged to the genus Endozoicomonas. The highest level of sequence similarit...
متن کاملPolaribacter atrinae sp. nov., isolated from the intestine of a comb pen shell, Atrina pectinata.
A novel Gram-staining-negative, aerobic, non-motile, yellow-to-orange carotenoid-type-pigmented and rod-shaped bacterium, designated strain WP25T, was isolated from the intestine of a comb pen shell, Atrina pectinata, which was collected from the South Sea near Yeosu in Korea. The isolate grew optimally at 20 °C, at pH 7 and with 2% (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولNovel polymorphic microsatellite markers isolated from the pen shell Atrina pectinata (Mollusca: Bivalvia: Pinnidae).
In this study, we isolated 21 novel polymorphic microsatellite DNA loci from the pen shell Atrina pectinata using magnetic-bead hybridization enrichment. The characteristics of these loci were tested using a population of 30 individuals collected from the Penglai coast, Shandong Province. The number of alleles ranged from 2 to 13, and polymorphism information content (PIC) varied from 0.1730 to...
متن کاملComparison between Wild and Hatchery Populations of Korean Pen Shell (Atrina pectinata) Using Microsatellite DNA Markers
Pen shell (Atrina pectinata) is a popular food source with a high commercial value in a number of Asian Pacific areas. The natural A. pectinata population has been declining continuously over the past several decades. Microsatellite DNA markers are a useful DNA-based tool for monitoring the genetic variation of pen shell populations. In this study, 20 polymorphic microsatellite (MS) DNA markers...
