Gas vesicles shapiro
WebShapiro et al first reported that protein-shelled, gas-filled GVs from Anabaena flos-aquae (Ana) and Halobacterium NRC-1 (Halo) with widths of 45–250 nm, lengths of 100–600 nm, ... Gas vesicles provide buoyancy for cells so that they can migrate vertically in water, thus attaining suitable growth conditions. WebGas vesicle echo-genicity in this configuration was detectable for over one week (Supplementary Fig. 1). Contrast was strongest at the highest fre-quency, with OD 2.0 Ana gas vesicles producing 27.0+4.1 greater scattering than buffer controls (Fig. 1f). The balance of scattering and attenuation differed between Ana and Halo gas vesicles.
