- 3M sodium acetate was added to the supernatant so that 10% (v / v) of the total volume was added, mixed with 2 times the volume of cold 95% ethanol, and allowed to stand at -20 ° C for 1 hour. .
- Figure 2 is an electrophoresis picture of genomic DNA of bacteriophage ⁇ CJ27, it can be seen that the genomic DNA of bacteriophage ⁇ CJ27 is more than 98 kb.
- M is DNA as a standard for measuring size.
- Figure 3 is an electrophoresis picture showing the SDS-PAGE results performed on the bacteriophage ⁇ CJ27, the major proteins of about 27.9 kDa, 51.8 kDa and 74.5 kDa size can be confirmed.
- the DNA of the bacteriophage ⁇ CJ27 was analyzed using a genetic analyzer FLX titanium sequencer (Roche). Genes were combined using Macrogen Inc., using GS and de novo assembler software (Roche). An open reading frame was performed using GeneMArk.hmm, Glimmer v3.02 and FGENESB software. The name of the transcription analysis framework was annotated using BLASTP and the InterProScan program.
- the base sequence of the bacteriophage showed various similarities to the base sequence of the previously reported bacteriophage (Enterobacteria phage HX01, complete genome), but it was confirmed that there is no bacteriophage in which all fragments were 100% identical. As a result, the bacteriophages could be identified as newly isolated bacteriophages.
- Table 1 shows the result of comparing the homology of the base sequence of bacteriophage ⁇ CJ27 with the translational base sequence of other bacteriophages.
- the DNA sequence of the prepared bacteriophage ⁇ CJ27 was analyzed using a genetic analyzer.
- pH solutions sodium acetate buffer solution (pH 4.0 and pH 5.0), sodium citrate buffer solution (pH 2.0 and pH 3.0) were prepared at 0.2 M each for the experiment.
- Figure 4 shows the acid resistance test results of the bacteriophage ⁇ CJ27. As shown in Figure 4, compared to the control bacteriophage ⁇ CJ27 was confirmed that the stable without losing the activity from pH 2.0 to pH 5.0.
- Figure 5 shows the heat resistance test results of bacteriophage ⁇ CJ27. As shown in FIG. 5, bacteriophage ⁇ CJ27 showed a decrease in activity of about 1 log or less until exposed for 1 hour at 60 ° C., and activity of 1 log or more was reduced at 120 minutes of exposure.
- bacteriophage ⁇ CJ27 shows the ability to infect the F-serum type F4, F5, F6, F18, etc., which is a major cause of swine diarrhea in a general pig farm, and has excellent efficiency in the field application. It is expected to indicate.
