Toxic Microcystis cracking cyanophage and separation method and application thereof

Abstract

The invention discloses toxic Microcystis cracking cyanophage and a separation method and application thereof. The toxic Microcystis cracking cyanophage is characterized in that the cyanophage is a MaSSC-P strain, is classified and named as Microcystis aeruginosa single-stranded DNA cyanophage MaSSC-P, collected at the China General Microbiological Culture Collection Center on 25th May, 2015 and numbered as CGMCC No.10598. A purified cyanophage suspension is added into a Microcystis water sample, and the toxic Microcystis cracking cyanophage has specific cracking effect on Microcystis in the water sample and has cracking effect on Microcystis aeruginosa, Microcystis wesenbergii and Microcystis viridis. The toxic Microcystis cracking cyanophage has the advantage of being capable of safely, efficiently and quickly cracking toxic Microcystis in fresh water.

Description

technical field

[0001] The invention relates to a toxic Microcystis lytic cyanophage, in particular to a toxic Microcystis lytic cyanophage and its separation method and application. Background technique

[0002] In recent years, human economic activities have become more and more serious, and various domestic sewage and production wastewater have been discharged into slow-flowing water bodies such as lakes, estuaries, and bays, causing excessive nutrients such as nitrogen and phosphorus in the water body to become eutrophic. The algae that causes is multiplied in great numbers, and the occurrence of " water bloom " becomes more and more serious, and wherein blue-green algae becomes the main alga that causes water bloom outbreak. "Water bloom" is one of the most serious environmental disasters in the world today. Among them, my country is one of the countries with the most serious outbreak of water bloom. About 75% of the lakes are facing different degrees of eutrophication ...
