Livestock Wastewater shall cause a high concentration of organic matter and nutrients such as rivers because of the lake and groundwater contamination, such as the accumulation of nutrients in the soil contained in the manure, livestock wastewater containing large amounts of organic matter that will flow to the river or appeal If eutrophication, and comfortable living environment to cause harm, such as odor and pest damage and can. Organic waste and organic waste, such as the world has a direct interest in acquiring the available resources and the development of clean energy from waste is a growing desire, is expected to contribute to the environment from waste materials industry growth by developing innovative technologies such as direct electrical energy production. In the case of livestock waste water and high concentration of organic material in addition to containing ammonia nitrogen, nitrate nitrogen for nitrification is created due to the electron acceptor is used as the fuel cell according to this has been reported to decrease the efficiency of electricity production. Therefore, to derive the electricity production efficiency due to organic concentration and ammonia nitrogen concentration in order to apply a microbial fuel cell (MFC) livestock wastewater treatment process in this study, and to derive the energy production potential with livestock waste water through the study. Lab. scale Reactor fabrication and operation to try to derive the reaction factor of the optimum operating conditions in accordance with the livestock wastewater applied through the evaluation of trends and removal efficiency of organic matter and nutrients in the microbial fuel cell. In addition, from the final research results, I try to present the direction of future research for the improvement of application possibilities and microbial fuel cell power generation efficiency of microbial fuel cell in the livestock wastewater treatment facilities.

Genetically modified (GM) papaya (Carica papaya L.) line 55-1 (55-1), which is resistant to papaya ringspot virus infection, has been marketed internationally. Many countries such as the European Union, Japan, and Korea have a mandatory safety assessment, approval and labeling regulations for GM foods. Thus, there is a need for specific methods for detecting 55-1. In this study, we established a real-time PCR detection method applicable to 55-1 for a variety of papaya products. The limit of detection was possible for fresh papaya fruit up to dilutions of 0.005% and 0.01% (weight per weight [w/w]) for homozygous SunUp and heterozygous Rainbow cultivars, respectively, in non-GM papaya. The 55-1 event-specific detection method observed parallelism (r2>0.99) between the concentration of line 55-1 cultivars and Ct values obtained in amplification plots at concentrations of 0.005-10% for SunUp DNA and 0.01-10% for Rainbow DNA. The method was applicable to the qualitative detection in various types of processed products (cocktail fruit, dried fruit, juice, etc.) containing papaya as a main ingredient. Monitoring papaya products for the presence of GM papaya were demonstrated using a P35S and T-nos real-time PCR detection method but no amplification signals were detected.

Mungbean (Vigna radiata) is a fast-growing, warm-season legume crop that is primarily cultivated in developing countries of Asia. We constructed a draft genome sequence of mungbean to facilitate genome research into the subgenus Ceratotropis and to enable a better understanding of the evolution of leguminous species. The draft genome sequence covers 80% of the estimated genome, of which 50.1% consists of repetitive sequences. In total, 22,427 high confidence protein-coding genes were predicted. Based on the de novo assembly of additional wild mungbean species, the divergence of what was eventually domesticated and the sampled wild mungbean species appears to have predated domestication. Moreover, the de novo assembly of a tetraploid Vigna species (Vigna reflexo-pilosa var. glabra) provided genomic evidence of a recent allopolyploid event. To further study speciation, we compared de novo RNA-seq assemblies of 22 accessions of 18 Vigna species and protein sets of Glycine max and Cajanus cajan. The species tree was constructed by a Bayesian Markov chain Monte Carlo method using highly confident orthologs shared by all 24 accessions. The present assembly of V. radiata var. radiata will facilitate genome research and accelerate molecular breeding of the subgenus Ceratotropis.

Purple sweet potato (PSP, Ipomoea batatas) has various biological effects including antidiabetic, anti-inflammatory, and antioxidant activities. In this study, the antioxidant activity of PSP after roasting were compared using DPPH, ABTS, and FRAP assays. In addition, the total phenolics and flavonoid contents, Maillard reaction products, and phenolic acid contents were measured to identify the factors that changed PSP,s antioxidant activity due to roasting. The roasted PSP exhibited significantly higher antioxidant activity than unroasted PSP. In particular, the PSP roasted at 200℃ for 10 min showed the highest antioxidant activity among all the PSPs that were roasted under different conditions. The total phenolic and flavonoid contents, Maillard reaction products and phenolic acid contents markedly increased, corresponding to the general increase in antioxidant activities after roasting. These results suggest that roasted PSP extracts are potential source of natural antioxidants that may be used in certain food applications.
