HPClas: A data‐driven approach for identifying halophilic proteins based on catBoost

mLife, Volume 3, Issue 4, Page 515-526, December 2024.
Abstract Halophilic proteins possess unique structural properties and show high stability under extreme conditions. This distinct characteristic makes them invaluable for application in various aspects such as bioenergy, pharmaceuticals, environmental clean‐up, and energy production.

Biofilms of Halobacterium salinarum as a tool for phenanthrene bioremediation

Biofouling, 2020
The use of hyperhalophilic microorganisms is emerging as a sustainable alternative to clean hydrocarbon-polluted hypersaline water bodies. In line with this practice, this work reports on the ability of the archaeon Halobacterium salinarum to develop biofilms on a solid surface conditioned by the presence of phenanthrene crystals, which results in the ...

Understanding the tolerance of halophilic archaea to stress landscapes

Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.
The tolerance responses of nine Haloarchaea species were analysed under 70 different conditions, including various salinities, temperatures, oxidative stress and the presence of metals. In general, all characterised species tolerated heavy metals, with a particularly striking tolerance to lithium. These results highlight the relevance of Haloarchaea in

Ion Transport of Biohybrid Asymmetric Membranes by pH and Light‐Cooperative Modulation

Advanced Materials Interfaces, 2020
Bacteriorhodopsin (bR) is an excellent light‐driven proton pump and plays a vital role in chemical and biological analytical processes, such as maintaining osmotic balance, intracellular acidity, and participating in photosynthesis.

Mono‐Exponential Current Attenuation with Distance Across 16 nm Thick Bacteriorhodopsin Multilayers

Advanced Functional Materials, Volume 34, Issue 48, November 26, 2024.
Electronic charge transport through multilayers of the protein bacteriorhodopsin (bR) shows an intriguing, mono‐exponential conductance attenuation with layer thickness up to ≈16 nm. A measured small attenuation coefficient β ≈ 0.8 nm−1 indicates efficient long‐range transport, which is mostly limited by charge injection at the interfaces. Abstract The

Nanobubble Contrast Enhanced Ultrasound Imaging: A Review

WIREs Nanomedicine and Nanobiotechnology, Volume 16, Issue 6, November/December 2024.
(A) Numerous nanobubble (NB; ~100–500 nm diameter) formulations have been studied for imaging applications. Most agents are (i) stabilized with a protein, polymer, or lipid shell. Several formulations have also been (ii) decorated with fluorescent labeling or (iii) functionalized with epitopes targeting overexpressed biomarkers on diseased tissue.

The Function of Gas Vesicles in Halophilic Archaea and Bacteria: Theories and Experimental Evidence

Life, 2012
A few extremely halophilic Archaea (Halobacterium salinarum, Haloquadratum walsbyi, Haloferax mediterranei, Halorubrum vacuolatum, Halogeometricum borinquense, Haloplanus spp.) possess gas vesicles that bestow buoyancy on the cells. Gas vesicles are also
