New Halonotius Species Provide Genomics-Based Insights Into Cobalamin Synthesis in Haloarchaea [PDF]

open access: yes, 2019
Hypersaline aquatic and terrestrial ecosystems display a cosmopolitan distribution. These environments teem with microbes and harbor a plethora of prokaryotic lineages that evaded ecological characterization due to the prior inability to cultivate them ...

The RosR transcription factor is required for gene expression dynamics in response to extreme oxidative stress in a hypersaline-adapted archaeon

open access: yesBMC Genomics, 2012
Background Previous work has shown that the hypersaline-adapted archaeon, Halobacterium salinarum NRC-1, is highly resistant to oxidative stress caused by exposure to hydrogen peroxide, UV, and gamma radiation.

Organic compatible solutes of halotolerant and halophilic microorganisms [PDF]

open access: yes, 2014
從苗栗通宵鹽山取得的粗鹽結晶中純化出十八株能生長在4.0 M高鹽的菌株。由16S rDNA序列的分析,確認這十八菌株均為極端高鹽太古生物,其中呈紅色菌落的HLR1~6這六株菌均屬於Haloarcula屬,而十二株淺紅色菌落的HLO1~6及白色菌落的HLW1~6屬於Natrinema屬。這十二株Natrinema屬的菌株均為長桿狀細胞,皆具有觸酶及氧化酶的活性,可以利用色胺酸、檸檬酸和葡萄糖,但都不能分解澱粉、明膠、脂質及卵磷脂,和Natrinema屬的菌株之16S rDNA相似度在97~99 %之間 ...

Charakterisierung des Zellzyklusses von Halobacterium salinarum [PDF]

open access: yes, 2008
H. salinarum ist einer von zwei archaealen Organismen, die synchronisiert werden können. Die Synchronisations-Methode konnte in dieser Arbeit optimiert werden. Nahezu 100 % aller Zellen teilen sich in einer Zeitspanne von einem Viertel der Generationszeit.
