Gas vesicle assembly in Microcyclus aquaticus [PDF]

open access: yesJournal of Bacteriology, 1975
When observed in the electron microscope intact gas vesicles appeared as transparent areas in whole cells of Microcylus aquaticus, whereas vesicles collapsed by centrifugation were not discernible. Within 5 min of suspending cells containing collapsed vesicles in growth medium, small transparent vesicles were detected.

The homologies of gas vesicle proteins [PDF]

open access: yesJournal of General Microbiology, 1992
In addition to GvpA, the main structural protein, an SDS-soluble protein has been found in gas vesicles isolated from six different genera of cyanobacteria. N-terminal sequence analysis of the first 30 to 60 residues of the gel-purified proteins showed that they were homologous to GvpC, a protein that strengthens the gas vesicle in Anabaena flos-aquae.

Nanosized Contrast Agents in Ultrasound Molecular Imaging

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Applying nanosized ultrasound contrast agents (nUCAs) in molecular imaging has received considerable attention. nUCAs have been instrumental in ultrasound molecular imaging to enhance sensitivity, identification, and quantification.

Gas Vesicle Nanoparticles for Antigen Display [PDF]

open access: yesVaccines, 2015
Microorganisms like the halophilic archaeon Halobacterium sp. NRC-1 produce gas-filled buoyant organelles, which are easily purified as protein nanoparticles (called gas vesicles or GVNPs). GVNPs are non-toxic, exceptionally stable, bioengineerable, and self-adjuvanting.

A Genome-Scale Atlas Reveals Complex Interplay of Transcription and Translation in an Archaeon

open access: yesmSystems, 2023
The scale of post-transcriptional regulation and the implications of its interplay with other forms of regulation in environmental acclimation are underexplored for organisms of the domain Archaea.

Gas vesicles in actinomycetes: old buoys in novel habitats? [PDF]

open access: yesTrends in Microbiology, 2005
Gas vesicles are gas-filled prokaryotic organelles that function as flotation devices. This enables planktonic cyanobacteria and halophilic archaea to position themselves within the water column to make optimal use of light and nutrients. Few terrestrial microbes are known to contain gas vesicles.

Characterization of Intracellular Structure Changes of Microcystis under Sonication Treatment by Polarized Light Scattering

open access: yesBiosensors, 2021
Cyanobacterial bloom is one of the most urgent global environmental issues, which eventually could threaten human health and safety. Sonication treatment (ST) is a potential effective method to control cyanobacteria blooms in the field.

Genetically encoded mediators for sonogenetics and their applications in neuromodulation

open access: yesFrontiers in Cellular Neuroscience, 2023
Sonogenetics is an emerging approach that harnesses ultrasound for the manipulation of genetically modified cells. The great penetrability of ultrasound waves enables the non-invasive application of external stimuli to deep tissues, particularly ...

Gas vesicles [PDF]

open access: yesMicrobiological Reviews, 1975
The gas vesicle is a hollow structure made of protein. It usually has the form of a cylindrical tube closed by conical end caps. Gas vesicles occur in five phyla of the Bacteria and two groups of the Archaea, but they are mostly restricted to planktonic microorganisms, in which they provide buoyancy.
