Gas Vesicles of Archaea and Bacteria

2006
Gas 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.

Lower limit of the gas permeability coefficient of gas vesicles

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1984
Abstract The 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

The Gas Vesicles and Buoyancy of Trichodesmium

1992
Gas 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.

EXPRESSION OF SEQUENCES OF NUCLEOTIDES CODING FOR GAS VESICLES

1990
The present invention relates to different recombinant E. coli cells comprising at least a nucleotide sequence corresponding to a structure of GV protein of a gas bladder or a variant of this sequence retaining the capacity for synthesis of said protein GV .
