Ultrasound Imaging Properties of Heterologously Synthesized Gas Vesicles from Halophilic Archaeon [PDF]

Nanomaterials
Biosynthetic gas vesicles (GVs), as novel nanoscale ultrasound contrast agents, exhibit unique potential in biomedical ultrasound imaging. For example, they are expected to have better tissue penetration through the tumor vasculature for detecting tumor ...

Meniscus-Mediated Imaging of Soft Biological Membranes Using 200 kN/m Ultra-Stiff 15 MHz MEMS AFM Probes. [PDF]

J Mol Recognit
ABSTRACT Coronaviruses, among other membrane‐enveloped viruses, can remain infectious on surfaces in ambient air for days. Many bacteria and fungi also expose their plasma membranes to air environments. Key survival strategies in air include hydrophobic coatings to prevent water loss and waxy or silica‐based resistant cell walls.

Solid-state fermentation as a tool for the culture of halophilic archaea: a practical experience for undergraduate students in biosciences [PDF]

Journal of Microbiology & Biology Education
The cultivation of halophilic microorganisms has been widely reported in liquid and semi-solid media. However, there are few reports on the use of solid fermentation for their cultivation. In the present work, the extreme halophilic Halobacterium sp. NRC-
