باکتری‌های اسیدلاکتیک، متداول‌ترین نوع باکتری‌هایی هستند که به‌عنوان پروبیوتیک معرفی شده‌اند. درمطالعه حاضر ابتدا به‌منظور جداسازی باکتری‌های اسیدلاکتیک، نمونه گیری از روده ماهی اسکار انجام شد و مقاومت به املاح صفراوی، تحمل شرایط اسیدی و قابلیت تخمیر قندها مورد یررسی قرارگرفت. در این تحقیق، از روده 50 ماهی اسکار نمونه‌‌برداری صورت گرفت و درمحیط کشت MRS<strong...
The Amazonian oscar is extremely resistant to hypoxia, and tolerance scales with size. Overall, ionoregulatory responses of small ( approximately 15 g) and large oscars ( approximately 200 g) to hypoxia were qualitatively similar, but the latter were more effective. Large oscars exhibited a rapid reduction in unidirectional Na(+) uptake rate at the gills during acute hypoxia (Po(2) approximatel...
Among vertebrate animals, only the mangrove rivulus (Kryptolebias marmoratus) was known to self-fertilize. Here, we use microsatellite analyses to document a high selfing rate (97%) in a related nominal species, Kryptolebias ocellatus, which likewise is androdioecious (populations consist of males and hermaphrodites). In contrast, we find no evidence of self-fertilization in Kryptolebias caudom...
Collaborative system composition during design has been poorly supported by traditional CASE tools (which have usually concentrated on supporting individual projects) and almost exclusively focused on static composition. Little support for maintaining large distributed collections of heterogeneous software components across a number of projects has been developed. The CoDEEDS project addresses ...
Oscar fish (Astronotus ocellatus), is one of the most popular aquarium fish, which needs more attention to provide health in breeding conditions. Due to the expansion of the use of probiotic bacteria in the aquaculture industry this research was conducted to evaluate the effects of Lactococcus lactis and Bacillus subtilis on digestive enzymes and hematology as health indices of Oscar. The exp...
