This study was carried out for isolation and characterization of ammonia oxidizing bacteria (AOB) from aquacultural place and sludges of waste water collected in Pusan. One autohophic AOB, Nitrosomonas sp. and 8 heterotrophic AOB (2 strains of Bacillus sp., 2 strains of Acinetobacter sp., Xanthomonas sp., Alcaligenes sp. Pseudomonas sp., and Sphingobacterium sp.) were isolated and identified. Variation of total ammonia nitrogen (TAN) and NO₂-N in mineral salt media contsining 10 ㎎/ℓ of NH₄Cl for 15 days in differents 9 strains was measured in order to examine the ablitity of ammonia oxidation. TAN was started to reduce after 4 days incubation and ca. 2 ㎎/ℓ of TAN was decreased after 15 days incubation by Nrtrosomonas sp.. At that time, NO₂-N was produced to 0.023∼0.036㎎/ℓ. Heterotrophic AOB showed the low ability of ammonia oxidation, 0.02∼0.04 ㎎/ℓ of TAN was decreased and NO₂,-N was produced to 0.01∼0.51 ㎎/ℓ after 15 days. When each strain of 8 heterotrophs was incubated in mimeral salt media containing 10 ㎎/ℓ NH₄Cl and 50 ㎎/ℓ glucose, and 50 ㎎/ℓ NH₄Cl and 5 g/ℓ glucose, the diminution of TAN was 1.12∼3.38 ㎎/ℓ and 1∼20 ㎎/ℓ, respectively.

이명숙(Myung Suk Lee),장동석(Dong Suck Chang),강지희(Ji Hee Kang) 한국수산과학회 1997 한국수산과학회지 Vol.30 No.5

A lactic acid bacteria which showed antimicrobial activity was isolated from dairy products and identified as Lactobacillus sp. according to the morphological, physiological and biochemical properties, which was named Lactobacillus sp. GM 7311. The bacteriocin of Lactobacillus sp. GM 7311 showed a broad range of inhibitory spectrum against some gram positive and negative bacteria. Especially, Proteus mirabilis was highly sensitive to bacteriocin and used as indicator strain for further investigation. The optimal condition for the production of bacteriocin was showed on MRS broth at 37℃ and pH 6.0. Bacteriocin production of this strain cultured under optimal condition was increased late logarithmic phase to early stationary phase. This bacteriocin was fully active at the pH range 2.0-5.0, also was stable at 100℃ for 60 min. at pH 5.0. But about 40% of bacteriocin activity was diminished by the treatment of acetone, ethanol, iso-butanol and ethyl ether during 2 hours at 4℃.

The antimicrobial effects of two disinfectants commonly used in food industry on Listeria monocytogenes ATCC 15313 were studied. The two disinfectants tested were commercial benzalkonium chloride (BAC) and sodium hypochlorite (NaOCl). Their effects were studied on cells suspended in disinfectants (in vitro) and in the sponge model with the disinfectants (in vivo). When cells were exposed to 0∼0.1% BAC and 0∼150 ppm NaOCl for 20 minutes, BAC and NaOCl concentration more than 0.25% and 100 ppm showed the antimicrobial effects respectively. This organism decreased rapidly during the first 0.5∼1 minute followed by a slower decrease during the rest of the exposure time. Fifteen ㎖ of cell solution (about 10^7 CFU/㎖ in the TSB) was mixed with 15 ㎖ of disinfectants in the sponge(6.0×4.0×4.0㎝), BAC and NaOCl concentration more than 0.1% and 300ppm showed the antimicrobial effects, and at 0.25% and 800 ppm diminished in cell numbers 3-log cycles during the first 20 minutes. In the case of sponge model, 15 ㎖ of cell solution and 15 ㎖ of disinfectants (0.25% of BAC, 800 ppm of NaOCl) were suspended in the sponge during 20 minutes, washing with 200 ㎖ of sterilized distilled water, and this sponge was transfered in the 100 ㎖ TBS, and then incubated at various temperature. The cells were increased about 1-log cycle during 24hrs at 5∼15℃. And the others temperature, the cells growth was in proporation to storage tepmerature and the cells were about 10^9 CFU/㎖ after 1∼3 days incubations.

Purpose: This study was to investigate the cancer screening rates and influence factors in island residents. Methods: The participants were 1,223 Shinan gun island residents. Data were collected using structured questionnaires from June 23th to September 8th, 2007 and analyzed using the SAS win 12.0 program. Results: The cancer screening rate was 49.9%. There were significant differences for sex, age, living with family, economic level, smoking, exercise, private health insurance, familial history, health concern. The highest practice rate was of stomach cancer (55.9%), which is gastric endoscopic exam. The most common motivation of getting a screening test was the concern of health (40.8%), and many had no recommender of the screening test (30.0%). 58.4% of the subjects were satisfied with the screeing tests and the most frequent reason of the satisfaction was ‘rapid result report’ (33.1%). The msot common reason of unsatisfaction was ‘long waiting time’ (25.7%). Most participants agreed with the necessity of cancer screening (74.9%). More than half participants said they would participate in another cancer screening tests in the future (51.9%). Private health insurance, exercise, health concern and smoking showed significant predictors (20.6%) of obtaining cancer screening. Conclusion: The results suggest that health care professionals should give more attention to help the residents obtain cancer screening tests. A further study is necessary to develop any effective intervention for people who do not practice cancer screening tests.
