The invention discloses a primer group for detecting halophilic bdellovibrio bacteriovorus based on high-throughput sequencing and application of the primer group. The primer group comprises primers of which the nucleotide sequences are as shown in SEQ ID NO.1 and SEQ ID NO.2. The invention further discloses a method for detecting the halophilic bdellovibrio bacteriovorus based on high-throughput sequencing. The invention also discloses a halophilic bdellovibrio detection method based on high-throughput sequencing. The method comprises the following steps: extracting template DNA of a sample to be detected; carrying out amplification on the template DNA by using the two primers; treating an amplification product, constructing a gene library, and carrying out high-throughput sequencing; after sequencing data is processed, statistical analysis is carried out, and the biological diversity of the halophilic bdellovibrio is obtained. According to the primer provided by the invention, diversity detection on the Halobacteriovorax can be realized, the primer has the characteristics of high sensitivity, good repeatability and the like, construction of a gene library is completed through one-step amplification, and existence and diversity of the Halobacteriovorax in an environment can be rapidly detected.

The utility model discloses a centrifugal device for bdellovibrio bacteriovorus production and belongs to the technical field of bdellovibrio bacteriovorus production and processing equipment. The bdellovibrio bacteriovorus filtering device comprises the centrifugal box, a rotating opening is formed in the bottom of the centrifugal box, the centrifugal box, a rotating frame, a clamping strip and a square groove are matched, the square strip and a bdellovibrio bacteriovorus filtering membrane can be inserted into the square groove, and the bdellovibrio bacteriovorus filtering membrane is clamped into the clamping groove, so that the filtering membrane is convenient to replace; an opening of the centrifugal box is closed through a hinge block and a box cover, a rotating ring and a rotating groove are used for abutting against a square strip and a bdellovibrio bacteriovorus filter membrane, and then a rotating frame is driven to rotate through cooperation of a driven gear ring, a driving gear and a rotating shaft; and the bdellovibrio bacteriovorus suspension in the bdellovibrio bacteriovorus filter membrane can be rotated, so that the bdellovibrio bacteriovorus suspension can be centrifuged, namely the bdellovibrio bacteriovorus suspension is filtered by the filter membrane to intercept large bacteria and allow small bdellovibrio bacteriovorus to pass through, and the filtrate is taken and separated.

The invention discloses a bdellovibrio sp. HCB242 strain, which is named as Bdellovibrio sp. HCB242, is preserved in the China Center for Type Culture Collection (CCTCC), and has the preservation number of CCTCC NO: M 20232314. The HCB242 strain is a brand new species of bdellovibrio, has the excellent characteristics of wide feed capturing spectrum, high adaptability to soil environment and the like, and can stably maintain growth in the natural environment of soil, so that the phagocytosis capability is maintained. The strain especially has a very efficient predation capability on ralstonia solanacearum, and has the potential of preventing and controlling crop diseases such as tomato bacterial wilt.

The application discloses a Bdellovibrio strain, named sp.HCB242, which is preserved in the China Center for Type Culture Collection and has a preservation number of CCTCC NO:M 20232314. Bdellovibrio The HCB242 strain is a new species of the Bdellovibrio genus, has the excellent characteristics of a wide predation spectrum and a strong adaptability to a soil environment, can stably maintain growth in the natural environment of the soil, and thus can maintain the phagocytosis ability. The strain has a very high predation capacity on Pseudomonas solanacearum, and has the potential for preventing and controlling crop diseases such as tomato bacterial wilt.

The present invention relates to a Bdellovibrio bacteriovorus 109J (Km240T) strain with accession No. KCTC15671BP, having antibiotic adaptability, and, more specifically, to a Bdellovibrio bacteriovorus 109J (Km240T) strain with accession No. KCTC15671BP, having antibiotic adaptability, the Bdellovibrio bacteriovorus 109J (Km240T) strain with accession No. KCTC15671BP being capable of effectively eliminating pathogens and removing gDNA and antibiotic resistance genes of pathogens, thereby preventing the spread of the pathogens, and thus present invention is expected to have synergistic effects when used with antibiotics.
