由於近年來，礁溪溫泉蕃茄受到青枯病(Ralstonia solanacearum)影響導致產量大減。投入種植的農民也越來越少，相關單位亦積極在研究有效處理方法。過去在農作物病蟲害管理上，幾乎都仰賴化學農藥。然而，化學農藥具有價格貴、易造成環境污染以及過量使用下容易產生抗藥性菌系等缺點。由於目前仍無根除方法，農民僅能靠輪作、土壤改良和採收前降低水位等方式降低損失。 本研究之主要目的係以Pseudomonas aeruginosa K-187菌株分解蝦蟹殼水產廢棄物，生產青枯病原菌(R. solanacearum)抑制物，探討有否助於抑制礁溪溫泉蕃茄青枯病及助其生長為研究目的。最適生產條件為：2%蝦蟹殼粉、0.1%K2HPO4、0.05%MgSO4•7H2O之培養基，於pH7、37℃振盪培養4天，可得最大抑制活性。

Recently the bacterial wilt of Jiaosi Tomato caused by Ralstonia solanacearum occurred. Because the R. solnacearum infection is the main cause of dead Jiaosi Tomato, this research will study the utilization of shrimp shell wastes by microorganism to produce antimicrobial agent and the effect of such an agent on the Jiaosi Tomato culture. The experiment will perform in two parts. First step: Studies on the antimicrobial agents produce by P. aeruginosa K-187, and identification of the strain. Second step:Field experiment. Maximum inhibitory activity was obtained when P. aeruginosa K-187 was grown aerobically in a medium consisting 2% shrimp and crab shell powder, 0.1% K2HPO4 and 0.05% MgSO4•7H2O at a pH of 7.0.
