Isolation of extreme halophiles from seawater.
Extreme halophilic bacteria were isolated from the ocean off the coast of Spain. All were gram-negative cocci. One isolate was compared to Halococcus sp. NCMB 757 and was found to have similar characteristics.
متن کاملExtreme halophiles synthesize betaine from glycine by methylation.
Glycine betaine is a compatible solute, which is able to restore and maintain osmotic balance of living cells. It is synthesized and accumulated in response to abiotic stress. Betaine acts also as a methyl group donor and has a number of important applications including its use as a feed additive. The known biosynthetic pathways of betaine are universal and very well characterized. A number of ...

If you were active on the web in July 1997, The spider bets that you surfed over to the US National Aeronautics and Space Agency (NASA) web site to watch live feedback of the Pathfinder Mission to Mars. And if you haven’t recently returned to outer space via cyberspace, it’s time to visit some of the web sites dedicated to space research, to learn about the growing field of astrobiology. Astrob...

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولDrastic differences in glycosylation of related S-layer glycoproteins from moderate and extreme halophiles.
The outer surface of the moderate halophilic archaebacterium Haloferax volcanii (formerly named Halobacterium volcanii) is covered with a hexagonally packed surface (S) layer glycoprotein. The polypeptide (794 amino acid residues) contains 7 N-glycosylation sites. Four of these sites were isolated as glycopeptides and the structure of one of the corresponding saccharides was determined. Oligosa...
