Description

technical field

[0001] The invention relates to the application of cold plasma technology in the field of microorganisms, in particular to the application of cold plasma in controlling enzyme catalytic activity. Background technique

[0002] Plasma is the fourth state of matter. It is a system composed of a large number of particles such as molecules, atoms, ions, and electrons. Since positive particles and negative particles have equal charges, they are macroscopically electrically neutral. Cold plasma is a kind of non-equilibrium plasma. The active particles have high energy and can maintain high enough chemical activity at low temperature (less than 50Β°C). Therefore, it has a very broad application prospect in the field of biochemical industry.

[0003] Enzyme is a special protein with catalytic activity and high specificity. Environmental factors have a great influence on its stability and activity. High temperature, high pressure, strong acid, strong alkali or ultraviol...
