中文摘要 | 本研究係將竹醋液添加不同去乙醯度及不同濃度之幾丁聚醣,以分光光度計於波長620nm下偵測光密度值(OD)之經時變化,分析竹醋液與幾丁聚醣之混合液對番茄青枯病菌(Ralstonia solanacearum)之抑制效果。試驗結果得知,竹醋液添加幾丁聚醣之混合液之抑菌效果優於僅添加竹醋液者,且隨幾丁聚醣之去乙醯度增加而抑菌效果愈佳。在本式驗中,以添加最高去乙醯度78%及濃度1.5%幾丁聚醣之竹醋液混合溶液具有最佳抑制番茄青枯病菌生長之效力。又經由分析型電子顯微鏡(AEM)觀察,可發現竹醋液混合溶液中之幾丁聚醣包覆青枯病菌,並使細胞莫呈現皺縮或破裂現象,推測混合液之抑菌機制為了幾丁聚醣上之正電荷N□基會與細菌細胞膜之負電荷互相作用,而達到抑菌的效果。 |
英文摘要 | The inhibition efficiencies of mixed solutions of bamboo vinegar and chitosan against Ralstonia solanacearum, an important bacterial wilt pathogen of tomato, were evaluated by examining the time-dependent changes in optical density (OD) values for different degrees of deacetylation (DDs) and concentrations of chitosan. The results indicated that the mixed solutions had better antibacterial activity than did only raw bamboo vinegar; and a higher DD and concentration of chitosan, resulted in better inhibition efficiencies. In this study, a mixed solution with a 78% DD and 1.5% concentration of chitosan showed the best inhibitory effect on bacterial growth. The cell membrane of the bacterium was damaged by chitosan, which was confirmed by analytical electron microscopy. The inhibition of bacterial growth may have been due to the interaction between the positive charge of N□ of chitosan and the negative charge of the bacterial cell membrane. |
