The immune system of halophilic archaea [PDF]

open access: yesMobile Genetic Elements, 2012
Prokaryotes have developed several strategies to defend themselves against foreign genetic elements. One of those defense mechanisms is the recently identified CRISPR/Cas system, which is used by approximately half of all bacterial and almost all archaeal organisms. The CRISPR/Cas system differs from the other defense strategies because it is adaptive,

Heterogeneity of small plasmids from halophilic archaea [PDF]

open access: yesJournal of Bacteriology, 1993
Small multicopy plasmids in three strains of halophilic archaea, SB3, GRB, and GN101, were found to be present in a cell as a population of related but not identical sequences. Two types of heterogeneity were observed: macroheterogeneity, represented by two major plasmid sequence versions homologous to each other by 80%, and microheterogeneity, in ...

Halophilic Archaea: Life with Desiccation, Radiation and Oligotrophy over Geological Times [PDF]

open access: yesLife, 2015
Halophilic archaebacteria (Haloarchaea) can survive extreme desiccation, starvation and radiation, sometimes apparently for millions of years. Several of the strategies that are involved appear specific for Haloarchaea (for example, the formation of halomucin, survival in fluid inclusions of halite), and some are known from other prokaryotes (dwarfing ...

Isocitrate lyase activity in halophilic archaea [PDF]

open access: yesFEMS Microbiology Letters, 1995
Eight species of halophilic Archaea were tested for the presence of isocitrate lyase activity. High activities (up to 100 nmol min−1 mg protein−1) were detected in Haloferax mediterranei and Haloferax volcanii when grown in medium containing acetate as the principal carbon source. Little activity was found in representatives of the genera Halobacterium

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Plant Lipid Droplets and Derived Lipidic Nano‐Assemblies: Structure, Biogenesis and Pharmaceutical Applications

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1322-1343, March 2026.
ABSTRACT Lipid droplets (LDs) serve as the primary storage site for neutral lipids in plant cells, with growing evidence supporting many additional biological roles, such as in lipid homeostasis, signalling, trafficking, inflammatory responses and inter‐organelle communication.

Antibiotic Sensitivity of Vibrio spp. and Shewanella algae Isolated From Brood and Egg of Mud Crab Hatchery

open access: yesAnimal Research and One Health, Volume 4, Issue 1, Page 55-66, February 2026.
Vibrio alginolyticus NBRC 15630, Vibrio parahaemolyticus ATCC 17802, Shewanella algae DW01, and Shewanella algae ATCC 51192 bacterial strains were found in the Mud crab brood and egg samples. All isolates were found to be sensitive to cefotaxime, chloramphenicol, gentamicin, and nitrofurantoin antibiotics.

An identity card for sabkha dolomite

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
An ‘identity card’ for modern sabkha dolomite from Qatar reveals its mineralogical, geochemical and microbial characteristics. This integrated dataset provides a benchmark for recognising similar dolomites in the rock record and for calibrating paleoenvironmental proxies used in climate and biosignature studies.
