Biogenic amines (BAs) are toxic nitrogenous compounds and formed by the microbial decarboxylation of amino acids during fermentation. Consumption of fermented foods high in BAs can pose the adverse health effects. The objective of current study was to develop a reduction method of BAs in fermented soybean paste by applying catechins during fermented koji manufacturing step. Analysis of BAs in fermented soybean paste was conducted using High Performance Liquid Chromatography (HPLC). The levels of Putrescine decreased for 63.7%, 60.1%, 76.1%, 73.4% for 0.3% addition of Epicatechin, Epicatechin gallate, Epigallocatechin, Epigallocatechin gallate, respectively. The levels of Cadaverine decreased for 24.3%, 34.3%, 42.6%, 37.2% for 0.3% addition of Epicatechin, Epicatechin gallate, Epigallocatechin, Epigallocatechin gallate, respectively. Especially, The best reduction effect of BAs appeared for 0.3% addition of Epigallocatechin. Current study demonstrated the potential use of catechins for reduction of biogenic amines in fermented soybean paste model. Finding from this research can practically guide fermented food industry by providing practical application of additives for reduction of BAs.

The need of reusing sewage sludge is highly increasing as the amount of domestic sewage sludge is growing and sewage management strategies were reinforced. Accordingly, in this research, we studied the composting possibility of sludge in sewage treatment plant J, using dryer facility with indirect system by conducting component analysis of dried sludge and experiment on cultivating crops. It was observed from the component analysis, that the dried sludge is appropriate for both decomposed manure standard of Ministry of Environment and fertilizer standard of Rural Development Administration. Besides, in the experiment on cultivating lettuce, the experimental group(soil + dried sludge) was superior to the control group(soil + bed soil) in apparent condition of leaves tensity and damage by disease and pest. In case of cultivating tomato, the experimental group showed stronger durability of fruits dangling on stems compared to the control group after 9 weeks. Consequently, the excess sludge dried by indirect heating system in the sewage treatment plant J is appropriate for the standard of both Ministry of Environment and Rural Development Administration and show good result in experiment on cultivating crops therefore it can be reused for composting.

By the strengthening of sewage treated quality law and the amount of sewage sludge every year is increasing in Korea. However, it is difficult to disposal of sewage sludge due to ocean dumping restriction. As an alternative to this, drying, incineration, anaerobic digestion etc. is applied, which is uneconomical in most be processed by the consumption of energy. In particular, anaerobic digestion technology has been installed in the sewage treatment 65 plats in Korea’s STP(sewage treatment plant). It is most of the digestion efficiency requires the application of improved technology to less than 50%. As an improvement technology for most anaerobic digester, ultrasonic, electronic beam, ozone etc. solubilization method using has been mainly used. Therefore, in this study, after the wet milling particles of sludge to subject the sludge that has not been decomposed in the digested sludge circulating fluid of anaerobic digestion, was let examine the characteristic at the time of ozonation. The size of the particles before and after the wet milling, which is the measurement at each 105.26 μm and 77.18 μm, solubilization rate is increased to 23.5%. When ozonation after wet milling using sludge is determined as possible to improve the efficiency.

At the time of the end of 2013, public sewage treatment facilities running nationwide facility capacity to over the 500 m³/day is 569 places at 25,085,810 m³/day, less than 500 m³/day facility capacity to 3,205 places is 244,592 m³/day. This is increased by about 2% annually in sewer diffusion rate 78.8% from 2003 to 2013 increased to 92.1%, but due to factors such as an increase in population. Also, every year changes in the inflow rate and the inflow sewage of concentration of sewage treatment facilities, has increased continuously. The concentration of organic matter in the sewage thus generated, which is removed by sewage treatment process, the most important process in the second process is a biological process. Most biological processes, maintaining DO, pH, and the environment of operation by a temperature sensor. But if you have these sensors to the original, there is a disadvantage that it is impossible to monitor the state of the microorganisms directly. And, therefore, in this study, we tried to study the possibility by direct measurement method the state of the microorganisms of activated sludge was used intermittently investigation and deviation capture of NADH of the light source of the biological reaction tank. In this study, measured is installed a detector capable deviation capture detection by a light source is irradiated to the fluorescence due to the reaction of NADH in microorganisms in light source unit and 460 nm which can be intermittently irradiated with UV at 340 nm, and devices, profile is made to be composed of a passage for receiving the fluorescence emitted microorganisms by irradiation with UV light microorganisms size diameter 200 mm, length 740 mm. Biological reactor of interest, and the activated sludge biological reaction tank of Gyeonggi A City sewage treatment plant to the subject, measurement points, was carried out in the total of four locations. The sensor was calibrated in the same conditions as zero state laboratory, this time when the NAD based on the water 0.2 m point current (A) is 50 mA, 100 mA, 200 mA, respectively 26, 48, 84.5 has been measured in the (intensity value). This is according to the increase in current value. Intensity also proportionally increased, is determined as indicating a direct electrical reception may show the ease of measurement. Also, salvaged and re-invasion enemy repeatedly re-dipping after, shows the Intensity value of 84.1 at 200 mA, it was found that the reproducibility is good. The results were tested using an actual immersion light measuring device using the intermittent investigation and variance capture method from bioreactor wastewater treatment plants in operation, changes in the value of the change in star Intensity of current, as the load is high, higher and the current value increases, the proportional is increased it is determined that the reproducibility is good, and those entering least a light source and the detection consumable parts rain due to the previous year and maintain than investigation and detection methods continuous light source.
