Problems solved by technology

However, the algicidal bacteria in the prior art are of a single species, and most of them have the ability to inhibit algae for a single algae, but the outbreak of large-scale water blooms often involves the action of multiple algae

Embodiment Construction

[0047] In order to make the object, technical solution and technical effect of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0048] The experimental materials and reagents used, unless otherwise specified, are conventional consumables and reagents that can be obtained from commercial channels.

[0049] Isolation, screening and identification of algicidal strains

[0050] (1) Isolation and screening of algicidal strains:

[0051] A landscape water body rich in algae cells was taken from a certain place in Guangzhou City for LB medium plate coating, and after 48 hours of constant temperature incubation at 35°C, different forms of microorganisms were separated and purified by streaking. The purified different mic...

Abstract

The invention discloses an alga-lysing microbial agent and application thereof. The microbial agent contains enterobacter and / or an enterobacter extract, and the enterobacter is selected from enterobacter hormaechei F2 or enterobacter cloacae. The microbial algicidal inoculant contains the enterobacter hormaechei F2 and / or the enterobacter hormaechei F2 extract, and has an obvious dissolution effect on microcystis aeruginosa in a water body, the algicidal rate reaches 95%, the algicidal rate on filamentous algae reaches 97%, the removal rate of algal cells in an actual eutrophic water body can reach 87.32%, and the removal rate of the microcystis aeruginosa in the actual eutrophic water body can reach 87.32%. The alga-lysing microbial agent has great application in water eutrophication treatment.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to an algae-dissolving microbial bacterial agent and its application. Background technique [0002] The outbreak of algal blooms in eutrophic water bodies is mainly caused by cyanobacteria. Anabaena anabaena is one of the main algal species that cause algae blooms. It has strong adaptability, and its occurrence frequency and damage range are second only to Microcystis Triggered by toxic blooms of cyanobacteria. Microcystis aeruginosa in Microcystis will release algal toxins during the growth process, which not only destroys the stability of the water ecosystem, but also affects the safety of human drinking water and poses a hazard to human health. [0003] Among the related technologies, there are three main technologies for controlling the flooding of cyanobacteria: physical methods, chemical methods and biological methods. Physical algae removal mainly uses methods such...
