Application of viburnum sargentii extracting solution as microcystis aeruginosa inhibitor

Abstract

The invention relates to application of a viburnum sargentii extracting solution as a microcystis aeruginosa inhibitor. The preparation method of the viburnum sargentii extracting solution comprises the following steps: drying viburnum sargentii, crushing the dried viburnum sargentii into powder, sieving, weighing the viburnum sargentii powder, adding into a triangular flask, adding distilled water, extracting for 30 minutes by using an ultrasonic cleaner, putting into a refrigerator, leaching overnight to obtain the viburnum sargentii extracting solution, and storing for later use. Accordingto the invention, the average inhibition rate of the prepared viburnum sargentii microcystis aeruginosa inhibitor on microcystis aeruginosa is 63.53%; the problems that after the photosynthetic activity of algae is damaged, the content of chlorophyll a is reduced, the membrane permeability is increased, and phycocyanin is sharply reduced are effectively solved; and the delustring property of a water body polluted by algae can be improved, normal growth of other aquatic organisms can be guaranteed, a theoretical basis can be provided for screening medicinal plants with an algae inhibiting effect, a test basis is provided for solving the problem of eutrophication of the water body, and a new technology is provided for researching and developing a biotechnology for treating blue-green algae.

Description

technical field [0001] The invention belongs to the field of ecological environment, and relates to eutrophication of water bodies, in particular to the application of an extract of Viburnum tianmu as an inhibitor of Microcystis aeruginosa. Background technique [0002] Water pollution is one of the top ten environmental pollution in the world, and water eutrophication is the most important water pollution problem facing the world. With the acceleration of industrialization and urbanization, a large number of nutrients such as nitrogen and phosphorus are discharged into the water body, which accelerates the eutrophication process of the water body. The eutrophication of the water body causes the abnormal reproduction of algae and other phytoplankton to form a "bloom". One of the main dominant species of cyanobacterial blooms is Microcystis aeruginosa, which has a high outbreak rate and releases algal toxins, which seriously threatens the living environment of other aquatic ...
