Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following examples.

[0014] In this embodiment, a strain capable of efficiently accumulating phosphorus in an anaerobic environment was screened from phosphate rock wastewater, and it was named AP06. The nucleotide sequence of the strain is shown in SEQ ID NO.1, including 755 bases . Using MEGA5 software to construct a phylogenetic tree, such as figure 1 As shown, the similarity of the AP06 bacterial strain and Aeromonas sobria is 99%. The preliminary identification of the AP06 bacterial strain is Aeromonas sobria (Aeromonas sobria), and the classification is named Aeromonas sobria (Aeromonas sobria). This bacterial strain was released in March 2016. On the 7th, it was preserved in the China Center for Type Culture Collection, the address is: Wuhan University, Wuchang District, Wuhan City, Hubei Province...

Abstract

The invention provides a strain of Aeromonas sobria (Aeromonas sobria) AP06, which was preserved in the China Center for Type Culture Collection on March 7, 2016, at the address: Wuhan University, Wuchang District, Wuhan City, Hubei Province, preservation number It is CCTCC NO: M2016093, and the nucleotide sequence of the strain is shown in SEQ ID NO.1, including 755 bases. Observed in the isolation medium, the colony of the AP06 strain is milky white, smooth, thick and opaque. Observed under a microscope, it is short rod-shaped. The Aeromonas sobria AP06 strain provided by the invention can be used to treat phosphorus-containing sewage, and the pH value is 7, the temperature is 30 ° C, and the phosphorus source is KH 2 PO 4 , under the condition that the inoculation amount is 7%, the phosphorus accumulation efficiency of the strain is greater than 86%.

Description

technical field [0001] The invention relates to an Aeromonas sobria (Aeromonas sobria) AP06 strain with phosphorus accumulation effect, a screening method of the strain and optimization of a phosphorus accumulation process, and belongs to the technical field of microorganisms. Background technique [0002] Water is one of the most basic resources for the survival and development of human beings and all living things. In recent years, the problem of eutrophication in water bodies has become more and more serious, making human beings face the dual challenges of water resource shortage and water environment pollution. Nitrogen and phosphorus pollutants are the main factors leading to the eutrophication of many inland lakes, reservoirs and even rivers. Among all known phosphorus removal methods, microbial remediation technology with low cost and no secondary pollution is an effective solution to water eutrophication. one of the ways. With the discovery of denitrifying bacteria,...
