The mechanical properties of the Microcystis gas vesicle [PDF]

Journal of General Microbiology, 1991
Gas vesicles isolated from the cyanobacterium Microcystis sp. retained their high stability and critical pressure on storage and could be held under a sustained pressure of 0.5 MPa without collapse. Application and release of pressures up to 0.5 MPa gave reversible changes in volume that indicated an elastic compressibility of 0.0087 MPa-1, which was ...

Control of algal growth in reservoirs with ultrasound [PDF]

, 2009
Algal blooms are a major worldwide water treatment concern due to their potentially harmful effects on humans and livestock. The main cause of algal bloom proliferation is eutrophication of water sources. Anthropogenic effects contribute significantly to
