Screening of Bacillus subtilis strains capable of producing extracellular hydrolases, including lipolytic enzyme was carried out. Within the scope of this study, total 61 strains were isolated from various domestic specific environmental samples such as seawater, soil, Jeju ranch, hot spring, salt farm, and fermented food and identified as Bacillus subtilis based on 16S rRNA sequences. Among the isolates, 4 strains had extracellular lipase activity. The growth profile of the strains revealed that 4 strains showed well growth at 50℃, 3 strains at 55℃, and pH 7.0. All strains could tolerate salinity up to 5%(w/v), 3 strains up to 10%(w/v), and only one strain showed growth at 15%(w/v). Additionally, amylolytic and proteolytic activities were detected in these strains. The highest lipolytic, amylolytic, and proteolytic activity was detected in Bacillus subtilis YS-YR 5A. These results demonstrate the potential application of extracellular hydrolase-producing Bacillus subtilis strains, especially strain YS-YR 5A, as fermentation starter to enhance the functionality and multiplication of functional natural products in the food/medicine/cosmetics/bio industries.

This study aimed to investigate the effect of amino acid additives to weaned piglet diets on the pH and volatile fatty acids of pig slurries. A total of 135 weaned 22 -day-old piglets (Yorkshire x Landrace x Duroc) were used in this 56-d study. The three dietary treatments were as follows: (1) Control as a basal diet, (2) 1% amino acid additive and (3) 2% amino acid additive. Both pH and acetic acid values at 71 and 78 days were significantly different in all treatment groups (p<0.05). In addition, significant differences in propionic acid values were observed among treatment groups at 64 and 78 days (p<0.05). However, pH, acetic acid, and propionic acid values did not differ between 1% and 2% amino acid treatment groups. In conclusion, adding 1% and 2% amino acid to weaned piglet diets reduced the pH, acetic acid and propionic acid contents of pig slurries by acting as a probiotic. This may help formulate increase management strategies for improving the pig housing environment.

The effects of essential oils on pH, pathogens, and volatile fatty acids (VFA) in two poultry litters were investigated through a lab study. Essential oil-added poultry litters were randomly divided to two groups: control (200 g poultry litter) and Treatment (50 g thymol/Briefly, 200 g broiler litter was treated with or without 50 g thymol (Control and T1, respectively; 1 groups) and 200 g duck litter was treated with or without 50 g carvacrol (Control and T2, respectively; 2 group). Adding thymol to broiler litter increased the pH, reduced pathogens, and did not affect VFA. Interestingly, adding carvacrol slightly reduced the pH of duck litter, but had no significant effect on reducing pathogens and VFA. This difference is probably because the essential oil used and the properties of the two litters are different. In addition, pH was thought to control the odor generated from the litter, but this has not been proven. Further field studies should focus on clarifying this point.

In this study, probiotic properties such as acid resistance, bile tolerance, intestinal adhesion and fat accumulation inhibition of lactic acid bacteria isolated from kimchi were investigated in order to develop probiotics effective anti-adipogenic effects. Among the 120 types of lactic acid bacteria isolated from kimchi, 42 types of lactic acid bacteria being to acid resistance, 35 types of lactic acid bacteria being to bile resistance, and 24 types of lactic acid bacteria being to both acid resistance and bile resistance were selected. These 24 types were tested for the intestinal adhesion ability which is an essential factor of probiotics’ function and L. rhamnosus GG was used as a positive control in this test. 10 types of lactic acid bacteria having the intestinal adhesion ability were selected. The selected 10 types of lactic acid bacteria were treated in 3T3-L1 cells and intracellular fat was stained with Oil Red O reagent to measure fat accumulation. As a result, in the group treated with lactic acid bacteria OS-15, 48, 102 and 120, fat accumulation was significantly decreased compared with the non-treated group. And the strain OS-48 showed the greatest inhibitory effect on fat accumulation. The lactic acid bacterium OS-48 was identified as Lactiplantibacillus plantarum by analysis based on 16S rRNA sequencing and was named Lactiplantibacillus plantarum OS-48. Therefore, based on the results of this study, L. plantarum OS-48 is expected to be very useful as probiotics with anti-obesity effect in the food industry such as fermented food and functional food.

This study was conducted to investigate the effects of adding Tenebrio molitor L Powder to broiler feed on fatty acid profiles in broiler breast meat. In total, 180 broiler chicks (1-day old Arbor Acres) were included. The birds were randomly divided into control and treatment groups, with 3 replicate subgroups each(30 birds per subgroup), and fed a diet for 35 days without (control) or with 1% Tenebrio molitor L powder (treatment). Among individual fatty acids, addition of Tenebrio molitor L. powder resulted in slightly higher C18:1n-9, C20:3n-3 and C20:3n-6 contents, and lower C18:2n-6 content compared withcontrols (p<0.05). No remarkable differences in total SFA and total USFA contents were found between groups. In conclusion, inclusion of Tenebrio molitor L. in broiler diets did not improve overall fatty acid profiles.

The purpose of this study is to extract climate element affecting coffee yield by growth period using data of production and cultivation area of coffee and climate data for 2000-2018. During the analysis period, the production of coffee in Vietnam has been consistently increasing, but Ðăk Lăk in the Central Highlands, the main cultivation area for coffee production, has recently stagnated in the trend of increasing yield. The yield of Lâm Đồng, located in the relatively highlands of the Central Highlands, is steadily increasing. Coffee yields of Ðăk Lăk is negatively correlated with the temperature during flowering period, and is also significantly negatively correlated with the maximum temperature and precipitation during the late growing period. On the other hand, Lâm Đồng, located at a relatively high altitude, has a positive correlation with temperature during the late growing period. It is analyzed that the lower the altitude, the higher the temperature, the lower the coffee productivity due to the high temperature appearance, and the lower the low temperature appearance in the high altitude region.

항로표지는 선박에게 위치정보 등 다양한 정보를 제공함으로써 해양사고 예방 및 해양환경 보호 등에 기여하고 있다. 이러한 항로 표지의 중요성을 인식하여 무역항을 입출항하는 선박에 톤당 24원의 항로표지이용료가 징수되고 있다. 그러나 24원의 항로표지이용료는 1999년에 책정된 이후 현재까지 유지되어 오고 있는 반면, 해운 및 항만 4.0 시대변화에 따라 자율운항 선박 및 스마트 항만운영 등을 위한 항로표지의 새로운 역할에 대한 수요는 점점 증가하고 있다. 따라서 본 연구의 목적은 이러한 해운 및 항만산업의 변화에 따른 적정한 항로 표지이용료의 추정에 있으며, 이를 위해 평택청을 대상으로 총괄원가를 회수하는 방법을 도입하였다. 항로표지이용료 추정은 연도별 및 누적 환산 연도별 2가지와 항로표지이용료 징수대상이 무역항 이용 선박임으로 평택청의 항로표지를 전체와 대상 항로표지로 구분한 총 4가지 경우로 추정하였다. 추정결과 평택청의 항로표지이용료는 53.78-71.62원(2019년 기준)으로 현재 24원보다 29.78-47.62원이 높게 추정되어 인상이 필요하였다. 이러한 연구결과는 항로표지의 역할을 고려한 관련 예산 운영과 정책 운용에 유용한 기초자료로 활용될 수 있을 것이다.

This study was conducted to investigate the efficacy of mixed probiotic on the immunity, productivity index and mortality rate in the broiler. Total of 120 one-day-old Ross broilers chicks were randomly assigned into two treatments (control dietary group and probiotic-treated group) with three replications of each treatment. The probiotic group broiler had a lower mortality rate than control during the experimental period. The productivity index in the probiotic group increased significantly than the control group. The weight of the bursa of fabricius was high in the probiotic-treated group than the control group. Activated the immunity level after fed the probiotic mixed diet compared to the control group. Furthermore, the probiotic diet significantly decreased the saturated fatty the control group. Whereas the probiotic mixed diet increased the unsaturated fatty acid than the control group. Afterward, the diet including probiotic induced positive impact on broilers immunity level. This indicates that a probiotic mixed diet could be protecting the intestine from the invasion of a pathogenic organism. It would be beneficial to the poultry industries by decrease the broiler mortality rate with elevated the immunity.

The present study aimed to examine the effects of dietary illite as a feed additive on the Haugh unit and fatty acid profiles of eggs. One hundred and twenty laying hens (48-week-old Hy-line Brown) were randomly assigned to one of the following two treatments: control or 2% illite powder. At 2 and 4 weeks, the Haugh unit values between the control and 2% illite powder groups were not significantly different (p>0.05). In addition, individual fatty acid content at 2 and 4 weeks did not differ between the treatments (p>0.05), except for palmitic (C16:0) and palmitoleic acid (C16:1) content. The addition of 2% illite powder caused no difference between the total saturated and total unsaturated fatty acids at 2 and 4 weeks (p>0.05). In conclusion, the addition of dietary illite at a rate of 2% did not improve the Haugh unit values or fatty acid profiles of eggs.
