Bacterial wilt, which is a major soil-borne disease with widespread occurrence, poses a severe danger in the field of tobacco production. However, there is very limited knowledge on bacterial wilt-induced microecological changes in the tobacco root system and on the interaction between Ralstonia solanacearum and fungal communities in the rhizosphere soil. Thus, in this study, changes in fungal communities in the rhizosphere soil of tobaccos with bacterial wilt were studied by 18S rRNA gene sequencing. The community composition of fungi in bacterial wilt-infected soil and healthy soil in two tobacco areas (Gengma and Boshang, Lincang City, Yunnan Province, China) was studied through the paired comparison method in July 2019. The results showed that there were significant differences in fungal community composition between the rhizosphere soil of diseased plants and healthy plants. The changes in the composition and diversity of fungal communities in the rhizosphere soil of tobaccos are vital characteristics of tobaccos with bacterial wilt, and the imbalance in the rhizosphere microecosystem of tobacco plants may further aggravate the disease.

To investigate the effect of the predominant fungal species from Korean traditional meju and doenjang on soybean fermentation, the enzymatic activity and amino acid production of twenty-two fungal strains were assessed through solid- and liquid-state soybean fermentation. Enzymatic activity analyses of solid-state fermented soybeans revealed different enzyme activities involving protease, leucine aminopeptidase (LAP), carboxypeptidase (CaP), glutaminase, γ-glutamyl transferase (GGT), and amylase, depending on the fungal species. These enzymatic activities significantly affected the amino acid profile throughout liquid-state fermentation. Strains belonging to Mucoromycota, including Lichtheimia, Mucor, Rhizomucor, and Rhizopus, produced smaller amounts of total amino acids and umami-producing amino acids, such as glutamic acid and aspartic acid, than strains belonging to Aspergillus subgenus circumdati. The genera Penicillium and Scopulariopsis produced large amounts of total amino acids and glutamic acid, suggesting that these genera play an essential role in producing umami and kokumi tastes in fermented soybean products. Strains belonging to Aspergillus subgenus circumdati, including A. oryzae, showed the highest amino acid content, including glutamic acid, suggesting the potential benefits of A. oryzae as a starter for soybean fermentation. This study showed the potential of traditional meju strains as starters for soybean fermentation. However, further analysis of processes such as the production of G-peptide for kokumi taste and volatile compounds for flavor and safety is needed.

최근 딸기 생산이 확대 되면서, 고품질 다수확이 가능한 딸기 우량묘에 대한 수요가 빠르게 늘고 있으며, 딸기 육묘에 관한 관심이 더욱 늘고 있다. 그러나, 육묘시 작물에 따른 포트 혹은 트레이 선정에 대한 연구는 거의 이루어지지 않고 있다. 또한, 마이크로버블의 세정 능력은 이미 산업현장에서 널리 알려져 있으나 이를 이용한 시스템 개발은 농업분야에서는 미비한 실정이다. 따라서, 딸기 육묘에 적합한 마이크로버블 시스템을 설계하여 실증 개발함으로써 딸기 육묘 농가의 자립능력을 제고하고, 딸기 육묘 생산시스템의 확대 하여 농가소득 증대에 기여하고자 한다. 실험방법은 생육에 적합한 육묘용 트레이를 선정하고, 마이크로 버블 시스템을 적용한 육묘와 기존 방법에 의한 육묘의 비교 실험하였다. 포트의 용량에 따른 뿌린 근부의 성장변화를 관찰하고, SEM 촬영을 통하여 딸기 뿌리근부의 조직의 치밀성을 확인하였다. 기존 저면관수의 경우 딸기탄저병 확산을 억제하지만, 반입에 의한 감염주의 발병을 억제하는 것은 아니다. 따라서 포트 및 트레이를 청결하게 관리할 필요가 있으며 이를 해결하기 위해 미세기포(micro-bubble)를 사용한 클리닝이 상당한 효과가 있는 것으로 확인하였다. 또한 조직의 치밀도을 측정하기 위해 딸기 육묘 조직을 SEM 촬영하여 분석하였으며, 미세기포를 이용한 딸기 육묘 방법이 기존의 딸기 육묘 방법에 비하여 조직이 치밀한 것으로 확인 되었다. 또한 배지량 및 육묘 트레이가 딸기 육묘의 성장에 영향을 미치며 제1액아가 １개밖에 발생하지 않는 포기가 많아지고 '눈 없는 포기'의 발생 현상들이 발생하고 있어 적정 육묘 트레이의 선택 및 배지량 조절하는 비교 실험을 통하여 해결하였다. 본 연구의 결과 개선된 육묘트레이를 사용함으로써 제1액아의 형성이 촉진되어 정과방 후의 제1액과 방의 수확량이 증대한다는 것에 의해서 １월 혹은 ２월부터의 수량이 증대되어 소득향상이 기대되며, 마이크로버블을 저면관수에 적용함으로써 트레이의 청결을 유지하여 병해를 예방하고 딸기모종의 조직을 치밀하게 함으로써 딸기의 우량육묘를 얻는데 기여 할 것으로 기대된다.

We compared the effects of supplementing $L-lysine{\cdot}SO_4$ to L-lysine HCl on growth performance, nutrient digestibility and nitrogen retention in weaning pigs. A total of 96 crossbred pigs, weaned at $21{\pm}3$ days of age and with an average initial body weight (BW) $6.23{\pm}0.01kg$, were given one of 4 treatments, which translated into 6 replicates of 4 pigs in each pen. The animals were randomly assigned to four dietary treatments according to a randomized completely block design (RCBD) as follows: 1) control-no synthetic lysine, lysine deficient (0.80% total lysine); 2) L-C (= 0.2% L-lysine HCl); 3) K-L-S (= 0.332% $L-lysine{\cdot}SO_4$, A company); 4) C-L-S (= 0.332% $L-lysine{\cdot}SO_4$, B company). Diets were formulated with corn, soy bean meal, and corn gluten meal as the major ingredients, and all nutrients except the lysine met or exceeded NRC requirements (1998). The lysine content of supplemented synthetic lysine was the same in all treatment groups except the control. No clinical health problems associated with the dietary treatments were observed. During the entire experimental period, body weight, average daily gain (ADG) and feed efficiency (G:F ratio) increased (p<0.01) in pigs fed the experimental diets supplemented with L-lysine??HCl or $L-lysine{\cdot}SO_4$ produced by A company, irrespective of the two synthetic lysine sources. Although the supplementation of $L-lysine{\cdot}SO_4$ produced by B company tended to improve the ADG and G:F ratio, significant differences were not seen among all treatments and tended to be lower than the L-C (L-lysine HCl) and K-L-S ($L-lysine{\cdot}SO_4$ groups using the product from A company). The digestibility of crude protein (CP) was increased by the supplementation of synthetic lysine (p<0.05), irrespective of the L-lysine source (L-C, K-L-S, C-L-S). The results of this study showed that ADG, G:F ratio, and CP digestibility improved when $L-lysine{\cdot}SO_4$ or L-lysine HCl was supplemented into the weaning pigs' diet. There was a clear difference in efficacy between the two $lysine{\cdot}SO_4$ products based upon the growth performance of weaning pigs. Consequently, the bioavailability of $lysine{\cdot}SO_4$ products should be evaluated before supplementation of synthetic lysine in swine diets.

● The current world is suffering abnormal climate caused by global warming. The main cause of global warming is greenhouse gas such as carbon dioxide. The carbon labeling system and carbon traceability system being pushed ahead in the agricultural sector is the policy for responding to climate change to reduce greenhouse gas emissions. To make this policy more effective and enhanced, the amount of carbon emissions should be calculated based on the kind of crops or the various businesses in the agricultural sector. Therefore, in order to estimate the accurate amount of carbon emissions, it is necessary to establish carbon dioxide emission intensity of various agricultural materials added onto the agriculture, and to calculate the amount of carbon dioxide emission for each crop according to agricultural production. The purpose of this study is to establish the amount of emission, emission per agricultural materials, of agricultural materials being added for crop production as a basic step, and emission intensity which can be used in the future market in order to estimate accurate amount of carbon emission in all the policies being promoted in the agricultural sector. Therefore, in this study, in order to build LCI D/B about organic fertilizers among many organic materials added onto the organic agriculture sector, one leading company in organic fertilizer production was selected and LCA was conducted for this leading company. We had to build the intensity and integrated average concept of intensity upon the two cases once production farmers for their own consumption and farms besides organic fertilizer company were categorized even if it's little amount. But in this study, individually produced organic fertilizers were excluded. Calculated results are following. Carbon emission of mixed expeller cake fertilizer in organic fertilizer was 1,106,966.89kg-$CO^2$ and emission intensity was 0.01606kg-$CO^2$, respectively. Total emission of mixed organic fertilizers was 241,523.2kg-$CO^2$ and emission intensity was 0.01705kg-$CO^2$. And total emission of organic compound fertilizers was 94,592.66kg-$CO^2$ and emission intensity was 0.01769kg-$CO^2$, respectively.
