Abstract:
A novel strain Azospirillum brasilense CW301 with nitrogen fixing ability as well as growth enhancing effect is provided to transfer the fixed nitrogen to plants and increase nitrogen absorption of the plants, so that the strain is used as a substitute for chemical fertilizer. A strain Azospirillum brasilense CW301(KACC 91224P) has nitrogen fixing ability as well as growth enhancing effect and is isolated from wheat. The biofertilizer contains Azospirillum brasilense CW301(KACC 91224P) and is prepared by culturing Azospirillum brasilense CW301(KACC 91224P). The growth of plants is promoted by soaking seeds of plants in the cultured medium of Azospirillum brasilense CW301(KACC 91224P), wherein the plant is tomato, Chinese cabbage, lettuce, cucumber, red pepper, Welsh onion or crown daisy.
Abstract:
본 발명은 고추 탄저병균에 대한 항진균 활성을 가지는 바실러스속( Bacillus sp. ) 균주에 관한 것으로, 특히 고추 탄저병을 발병시키는 병원균인 코레토트리쿰( Colletotrichum sp. )에 대하여 강력한 포자 억제 활성을 가지는 대사산물을 생산함으로써 친환경 농자재로 사용하여 고추에 발병하는 탄저병을 감소시킬 수 있으며, 동시에 현재 사용되고 있는 유기합성 농약의 폐해성을 감소시키고, 고추의 상품성 및 생산성을 증대시킬 수 있는 항진균 활성을 가지는 바실러스속( Bacillus sp. ) YJH-051 균주 및 이를 이용한 고추 탄저병의 방제방법에 것이다. 고추, 바실러스속 균주, 탄저병, 코레토트리쿰, 항진균
Abstract:
A novel Bacillus sp. YJH-051 strain is provided to produce metabolites having strong spore inhibiting activity against Colletotrichum sp., a pathogenic bacteria causing anthracnose, thereby being used as an environment-friendly farming material for decreasing the anthracnose and increasing the marketability and productivity of hot pepper. A Bacillus sp. YJH-051 strain having antifungal activity against Colletotrichum sp. is deposited as a deposition number of KACC91195P. A method for controlling anthracnose comprises a step of treating hot pepper fruits or hot pepper cultivation soils with the Bacillus sp. YJH-051 strain or a metabolite thereof.
