Abstract:
본 발명은 감귤껍질 추출물, 천연초 줄기 및 천연초 열매로 이루어진 군으로부터 선택된 1종 이상을 유효성분으로 포함하는 미생물 배양배지에 관한 것이다. 본 발명의 미생물 배양배지는 저렴하고 쉽게 구입할 수 있는 천연소재만을 사용한 친환경 천연배지로서, 이를 이용하여 미생물을 생육하는 경우 일반 시중에서 판매되는 고가의 합성배지와 비교하여 미생물의 생육이 동등하거나 그 이상으로 생육되는 효과가 있다. 또한 본 발명의 배지에서 미생물을 배양할 경우 미생물은 식물 병원균에 대하여 항균효과가 뛰어난 천연길항물질을 생산할 수 있기 때문에, 본 발명의 배지는 생물농약의 대량 생산용 배지로서 유용하게 사용될 수 있다.
Abstract:
PURPOSE: A natural biomass silica nanopowder with an excellent contaminant removal ability extracted from a cornstalk pellet and a manufacturing method thereof are provided to selectively manufacture an amorphous silica, which is a highly graded silica, by controlling pH, and a mineral silica can be replaced as a corn stalk is recycled as a biomass resource. CONSTITUTION: A manufacturing method of a natural biomass silica nanopowder with an excellent contaminant removal ability extracted from a cornstalk pellet comprises steps of: pre-processing a cornstalk pellet ash to remove minerals other than silica, extracting the silica by controlling pH to be 6 to 11 in an aqueous solution including the pre-processed silicon, and obtaining a silica nanopowder by centrifuging and drying the extracted silica.

Abstract:
PURPOSE: A medium for culturing microorganisms containing citrus rind extract or Opuntia humifusa stems or fruits is provided to ensure antibacterial effect against plant pathogen. CONSTITUTION: A medium for culturing microorganism contains citrus rind extract, Opuntia humifusa stems or fruits as an active ingredient. The microorganism includes Bacillus species including Bacillus subtilis or Bacillus amyloliquiefaceiens. A method for manufacturing natural antagonistic materials against plant pathogen comprises: a step of preparing the medium containing the citrus rind extract, Opuntia humifusa stems or fruits; a step of culturing the microorganism in the medium; a step of centrifuging the culture liquid to obtain supernatant; and a step of filtering supernatant to completely remove microorganism.
Abstract:
PURPOSE: A plant growth control method using LED light and an antioxidant enzyme growing strategy are provided to increase production by controlling the growth of agricultural products. CONSTITUTION: A plant growth control method using LED light comprises the following steps: controlling plant growth by selecting LED light of blue light, green light, or red light. If the LED light is red or green light, length growth of the plants is promoted. The structure of the plant is secured if the LED light is the blue light. An antioxidant enzyme growing strategy for plants using LED light increases an antioxidant enzyme of the plants by irradiating plants with blue short wavelength LED light. The blue light has the wavelength band of 460 nanometers.
Abstract:
PURPOSE: A novel bacillus amyloliquefaciens jbc36 and a composition comprising thereof for controlling plant pathogens are provided to expand antagonistic effect on fungal virus and improve control effect on green and green molds of fruits. CONSTITUTION: A novel bacillus amyloliquefaciens jbc36 has antagonistic effect on phytopathogen. The strain shows excellent antagonistic effect on pathogen which generates diseases in fruits. The fruits include tangerine, pear, and apple. A phytopathogen natural antagonistic material can be obtained by separating from culture fluid of the bacillus amyloliquefaciens jbc36(deposit number: KACC 91582P) strain. A manufacturing method of the natural antagonistic material comprises the following steps: forming culture fluid by culturing bacillus amyloliquefaciens jbc36(deposit number : KACC 91582P) strain; removing the strain from the culture fluid; and extracting protein by processing the extraction solvent in the culture fluid which strain is removed. A composition for controlling phytopathogen includes culture fluid of the bacillus amyloliquefaciens jbc36(deposit number : KACC 91582P) strain or the same strain as an active ingredient.
