Differentially Expressed Proteome of Microcystis under Short-time Ultrasonic Stress

[...]algae-rich water would block filter, and thus increase the times of back wash and drug consumption. [...]the service life period of pipe network would be shortened, and the cost for water distribution would be improved. [...]the inhibitory effect of ultrasonic wave on Microcystis is not only reflected by the simple physical sedimentation effect, but also means a complicated slow physiological and biochemical process. [...]there were few reports on the molecular stress response of Microcystis to short-time ultrasonic stress, and very few reports on the influence mechanism of shorttime ultrasonic wave on the expression of Microcystis proteins, which retards the development of ultrasonic algae removal technique. [...]on the basis of the action mechanism of longtime ultrasonic wave on algal aggregation and sedimentation, short-time ultrasonic wave was selected as the stress factor of alga, and the differences in the expression quantities and kinds of Microcystis proteins caused by short-term ultrasonic wave were studied at the level of molecular biology, so as to provide a scientific basis for the determination of action mechanism of short-time ultrasonic wave-enhanced algae removal technique.
