Abstract: The present invention relates to a TRO analyzer of ballast water in a ship, including: a sensor body having a plurality of electrodes and a temperature sensor insertedly disposed in one end thereof; a protection cap coupled to one end of the sensor body to protect the exposed end portions of the plurality of electrodes and the temperature sensor and having a plurality of introducing and discharging holes formed penentratedly on a portion or the whole portion thereof; a sensing chamber formed between the protection cap and the sensor body; and an ultrasonic generator fixedly disposed inside the plurality of electrodes and the temperature sensor on one end of the sensor body to discharge the ballast water introduced into the sensing chamber through the plurality of introducing and discharging holes of the protection cap.

Abstract: The present invention provides a fed-batch culture method comprising a step of fed-batch-feeding a carbon source base and a base in such a manner that the pH level can be maintained at a level suitable for the growth of microorganisms for fermentation of a carbon source. The present invention also provides a method for preparing organic acids using the fed-batch culture method. The present invention fed-batch-feeds a neutralizing agent such as ammonium bicarbonate, ammonium carbonate or alkali metal-containing weak base, and a carbon source substrate in preparing organic acids by microorganism fermentation. Thus, a pH level suitable for the survival of microorganisms for carbon source fermentation can be maintained, and the speed of injecting the carbon source base which is the source material can be appropriately adjusted.

Abstract: Disclosed is a method of preparing alkyl butyrate, which comprises: (a) producing a fermented liquid containing butyrate salt through a fermentation process using butyric acid-producing strains; (b) obtaining an extracted liquid containing butyric acid from a continuous extracting apparatus using an extraction solvent, after converting the butyrate salt into butyric acid by adding an inorganic acid except for carbonic acid or carbon dioxide into the fermented liquid, wherein the continuous extracting apparatus includes a plurality of extraction plates which are installed inside an extraction column and perform a reciprocating motion vertically, and the broth and the extraction solvent are supplied to upper and lower portions of the column, respectively; and (c) reacting the extracted liquid and alcohol having a carbon number of 4 or less or a mixture thereof in an esterification reactor to convert a resultant product into alkyl butyrate.

Abstract: Provided are a method for removing and/or absorbing greenhouse gases using aquatic plant and/or algae having a greenhouse gas absorbing performance and resistance to toxic substances, a method for producing bioenergy using predators with high fatty acids, and a method for producing bioenergy including cultivating aquatic plant and/or algae having a greenhouse gas absorbing performance and resistance to toxic substances, while supplying a waste gas mixture to the aquatic plant and/or algae, (S2) cultivating predators having a capability to prey on the aquatic plant and/or algae while supplying the aquatic plant and/or algae to the predators, (S3) harvesting the predators, and (S4) converting the harvested predators into bioenergy.

Abstract: The present invention relates to a composition for the treatment of gout, comprising an Angelica gigas Nakai extract which inhibits xanthine oxidase to reduce uric acid in the blood or urine, thereby being effective in the treatment of gout. Further, the present invention relates to a composition for the prevention of inflammation in gout, comprising an Angelica gigas Nakai extract which has an inhibitory effect on the inflammation-inducing enzyme Cox-2. The Angelica gigas Nakai extract of the present invention is a liquid concentrate consisting of 98% by weight or more of decursin and decursinol angelate as main ingredients, and for administration to human, it is extracted with water and ethanol only as an extraction solvent. In addition, a purification method using a difference in temperature and solubility is used, in order to increase its purity.
