摘要：
The present invention discloses aStreptomyces misionesisKHY26, a cultivation method for increasing the KHY26 and a use for controlling plant pathogens. The cultivation method comprises incubating the KHY26 in a predetermined medium having a specific composition for cultivation under a specific condition for a specific time period to obtain a fermented product of the KHY26 having a high concentration. The KHY26 has an antibacterial activity to inhibit growth of many plant pathogens includingLasiodiplodia theobromae,Colletotrichum gloeosporioides, andMeloidogynespp. that exists inCucurbitaceae,Solanaceaeor other plants.Accordingly, the KHY26 can be used as a biological pesticide for preventing plant pathogens includingMeloidogynespp. inCucurbitaceae,Solanaceaeor other plants.本發明係關於一種鏈黴菌(Streptomyces misionesis)KHY26菌株及其增量培養方法與防治植物病原微生物之用途；鏈黴菌KHY26菌株之培養方法包含以特定成分之培養基，於一特定培養條件下培養一特定時間，以獲得高菌量濃度之鏈黴菌發酵產物；鏈黴菌KHY26菌株對蓮霧黑腐病菌(Lasiodiplodia theobromae)、炭疽病菌(Colletotrichum gloeosporioides)及瓜類、茄科或其他作物之根瘤線蟲(Meloidogynespp.)等植物病原微生物具抗生活性，能抑制包含植物寄生性線蟲在內之多種植物病原微生物的生長，並可實際應用做為防治瓜類、茄科或其他作物之根瘤線蟲等植物病原微生物之生物農藥。
