Membranes having an a high content of cardiolipin were isolated from an extremely halophilic archaeon Halorubrum sp. Absorbance difference spectra of detergent-solubilized plasma membranes reduced by dithionite suggested the presence of b-type cytochromes. Non-denaturing gel electrophoresis revealed only one fraction having TMPD-oxidase activity in which cardiolipin was the major lipid componen...
مقدمه : نمکدوستها، به ویژه هالوآرکیها یکی از مهمترین گروههای میکروارگانیسمهای افراطیدوست هستند. هیدرولازها ی نمکدوست بسیار مطالعه شدهاند و برای کاربردهای صنعتی و زیست فنآوری مورد توجه هستند. با توجه به اهمیت هیدرولازهای نمکدوست، مطالعه حاضر اولین گزارش در مورد خالصسازی آنزیم آمیلوپولولاناز از یک آرکی نمکدوست است . مواد و روش ها: آرکی نمکدوست Halorubrum سویه Ha25 آنزیم آمیلو...
Halobacteria require high NaCl concentrations for growth and are the dominant inhabitants of hypersaline environments above 15% NaCl. They are well-documented to be highly recombinogenic, both in frequency and in the range of exchange partners. In this study, we examine the genetic and genomic variation of cultured, naturally co-occurring environmental populations of Halobacteria. Sequence data...
The ability to silence the activity of genetically specified neurons in a temporally precise fashion would provide the opportunity to investigate the causal role of specific cell classes in neural computations, behaviours and pathologies. Here we show that members of the class of light-driven outward proton pumps can mediate powerful, safe, multiple-colour silencing of neural activity. The gene...
BACKGROUND Prior research on the microorganisms associated with the brine shrimp, Artemia franciscana, has mainly been limited to culture-based identification techniques or feeding studies for aquaculture. Our objective was to identify bacteria and archaea associated with Artemia adults and encysted embryos to understand the role of microbes in the Artemia life cycle and, therefore, their impor...
