Haloarchaea are the dominant microbial flora in hypersaline waters with near-saturating salt levels. The haloarchaeal diversity of an Australian saltern crystallizer pond was examined by use of a library of PCR-amplified 16S rRNA genes and by cultivation. High viable counts (10(6) CFU/ml) were obtained on solid media. Long incubation times (> or =8 weeks) appeared to be more important than the ...
BACKGROUND Goa is a coastal state in India and salt making is being practiced for many years. This investigation aimed in determining the culturable haloarchaeal diversity during two different phases of salt production in a natural solar saltern of Ribandar, Goa. Water and sediment samples were collected from the saltern during pre-salt harvesting phase and salt harvesting phase. Salinity and p...
The Halobacteria are known to engage in frequent gene transfer and homologous recombination. For stably diverged lineages to persist some checks on the rate of between lineage recombination must exist. We surveyed a group of isolates from the Aran-Bidgol endorheic lake in Iran and sequenced a selection of them. Multilocus Sequence Analysis (MLSA) and Average Nucleotide Identity (ANI) revealed m...
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 آمیلوپو...
No systems have been reported for genetic manipulation of cold-adapted Archaea. Halorubrum lacusprofundi is an important member of Deep Lake, Antarctica (~10% of the population), and is amendable to laboratory cultivation. Here we report the development of a shuttle-vector and targeted gene-knockout system for this species. To investigate the function of acetamidase/formamidase genes, a class o...
