Function and biosynthesis of gas vesicles in halophilicArchaea
Journal of Bioenergetics and Biomembranes, 1992The proteinaceous gas vesicles produced by various microorganisms including halophilic Archaea are hollow, gas-filled structures with a hydrophobic inner and a hydrophilic outer surface. The structural components of gas vesicles and their biosynthesis are still under investigation; an 8-kDa polypeptide appears to be the major constituent of the gas ...

Lower limit of the gas permeability coefficient of gas vesicles
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1984The gas vesicles found in various planktonic prokaryotes are hollow, rigid structures permeable to gases. They collapse when the difference between the external hydrostatic pressure and internal gas pressure exceeds their critical pressure (usually about 0.6 MPa). It was found that dried gas vesicles would survive exposure to gas pressures

Gas Vesicles of Archaea and Bacteria
2006Gas vesicles are hollow proteinaceous structures of spindle or cylinder shape produced by many cyanobacteria,heterotrophic bacteria and Archaea. Because of their gas content, gas vesicles decrease the cell densityand provide neutral or even positive buoyancy to cells. The rigid wall is formed solely from protein andis freely permeable to gas molecules.

The Gas Vesicles and Buoyancy of Trichodesmium
1992Gas vesicles provide Trichodesmium colonies with buoyancy. When the sea is calm the colonies float up and accumulate at the surface where they will be conspicuous to remote sensors. Under rough conditions they are mixed down, sometimes to great depths, but they may float back rapidly by virtue of their low density and large size.
