It is about.

Rapid economic development, explosive urban population and improvement of living moisture increase the discharge of various industrial wastes, domestic waste and septic and septic tanks and livestock wastes, including the increase of water volume.

As the discharge of wastewater increases rapidly, environmental problems such as serious water pollution have emerged, and development of a method for treating wastewater efficiently and economically is required.

However, although the water quality is rapidly being contaminated, many researches for the preservation of the water environment have been actively conducted, and heavy metals have been treated well, but nitrogen nitrate, ammonia nitrogen, phosphorus, and toxic bacteria are much more effective than facilities with enormous treatment efficiency. low.

In addition, the pollution of the sea is increasing, and due to the depletion of fish stocks, the production of fry and fish families has recently been made, and in general households, fish tanks are prepared to raise various fish directly.

However, the fatal problem was caused by the strains (Pseudomonas fluorescens bacteria, Aeromonas hydrophila bacteria) which are the biggest problem in the production of fry.

As a conventional method for filtration of pompon farms, Korea Patent Office Patent Publication No. 1997-014557 (January 28, 1997) used the ultrafiltration membrane or the microfiltration membrane during the water filtration process to supply the pomace farm to the pomace farm. By eliminating microorganisms and viruses, sterile water was supplied to the fry tanks to reduce the cost of drug purchase and to prevent the death of fish caused by the bottle.

However, this conventional water filtration method has a drawback that it is not possible to sterilize a strain causing a fatal problem.

In addition, the filtration filter, etc. should be given to the replacement periodically, there was a problem that the maintenance is difficult due to the high cost of replacement.

To a 300 ml Erlenmeyer flask, add 6.0 ± 0.5 g of a test sample [antibacterial sample] to 100 ml of sterilized neutral solution.

After the inoculation of the test bacteria solution, the cells were incubated for 24 ± 1 hours at 120 rpm and 37 ± 1 ° C.

Separately, the same test solution was added to the neutralization solution containing no sample, and then prepared as a control experiment solution.

After the bacterial solution was extracted from the test sample and the control sample, the number of bacteria was measured by culturing on a plate medium to determine the reduction rate of the control sample.

In this case, the initial dilution of all experiments was carried out by neutralizing with D / E Neutralizing Broth (DIFCO), and when the bacteria were grown in the medium, the number of bacteria on the medium was multiplied by the dilution factor. If the bacteria do not proliferate, the product was multiplied by the dilution factor made in the neutralization step and expressed as "less than 10" (<10).
