preparation example Construction

[0037] The preparation method of described untreated bacterial liquid comprises:

[0038] (1) Get the Pseudomonas mendoza preserved in the refrigerator, draw a line on the nutrient broth solid medium plate, and culture it at a temperature of 26-33°C for 10-16h until a single colony grows;

[0039] (2) Inoculate a single colony of Pseudomonas mendoza into the nutrient broth liquid medium, and cultivate it for 10-16h to the logarithmic growth phase under the condition that the temperature is 26-33°C and the number of revolutions is 150-250rpm, and then press 0.5-2% of the added amount was transferred to fresh nutrient broth liquid medium, and continued to cultivate to the logarithmic growth phase according to the above conditions to obtain untreated bacterial liquid;

[0040] (3) centrifuging the untreated bacterial liquid, collecting the centrifuged bacterial cells, and resuspending them with sterile water to obtain bacterial supersuspensions;

[0041] (4) Collect the supernat...

Abstract

The invention discloses a method of degrading spirulina. The method comprises the steps of inoculating a degrading bacterium solution according to an addition level of 0.01-10% into a spirulina culture solution for joint culture under conditions of a temperature of 20-40 DEG C, a pH (potential of hydrogen) of 5-10, and illumination intensity of 1600-2300lux, wherein the degrading bacterium solution is prepared from pseudomonas mendocina that is collected in Guangdong Microbial Culture Collection Center (GDMCC) on December 8, 2017 and has a biological collection number of GDMCC 60297. The method adopts the degrading bacterium solution to degrade the spirulina; an input amount is small; the treatment time is short; and a removal rate is high.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method for degrading spirulina. Background technique [0002] In recent years, with the rapid economic development and the continuous improvement of the quality of life, more and more nutrient-rich and complex production and domestic wastewater has been discharged into rivers and lakes. These waste water containing a large amount of pollutants such as nitrogen and phosphorus cause eutrophication of the discharged water body, which seriously leads to the outbreak of blue-green algae and destroys the ecological environment of the water body, which not only threatens the survival of aquatic organisms, but even threatens the health of human beings. In recent years, the eutrophication of domestic freshwater bodies has become more and more serious. A large number of algae have been found in some large lakes, reservoirs and aquaculture water bodies, and serious cyanobacteria b...
