 研究成果
 
1
Trichoderma harzianum ETS323對植物病源真菌存在時,胞內、外蛋白質體著手了解生物防治之分子機制。Two Manuscripts將送Fungal Genetic and Biology (No. 1 in Fungal research related journals)審查。

Trichoderma harzianum ETS323對植物病源真菌存在時,胞外代謝物著手了解生物防治之分子機制。從Trichoderma harzianum ETS323大量純化出二種能抑制植物病源真菌菌絲生長與提昇作物種子萌芽及根系發展的anthraquinones的衍生物chrysophanol及pachybisin。進一步了解T. harzianum生物防治的機制。此結果專利申請中,並發表於Journal of Biochemical and Biophysical Methods。
3
chrysophanol及pachybisin 據有protein photocleaver 性質,manuscript已送Journal審查。
4
Crystal structure of xylanase from Trichoderma harzianum ETS323, its structure of function and enzymetic mechanism investigation.
5
將來自黑殭菌的四種黑殭菌素(destruxins from Metarhizium anisoplia) DE、DA、DMDB及DB純化分離,黑殭菌素應用於病蟲害之防治,另一方面也能抑制B型肝炎病毒。將此純化的四種destruxins以旋光分光儀(Circular Dichroism)分析,發現destruxins的二級結構具有β-turns的結構。將四種標準品溶於氯化烷中,可得到四種差異極大的圖譜,利用這四種圖譜做基本的母圖,可應用於destruxins的快速鑑定。此外,在模擬生物體內環境下,將各destruxins以相同比例混合。以CD分析,顯示destruxins會以單体的模式存在來產生生物活性的特性較高。此結果發表於Journal of Biochemical and Biophysical Methods (SCI, impact factor 1.211, 50% in Biochemical Methods category) (in press)。

已經從T .harzianum ETS323純化出四種細胞壁分解酵素,其中β-glucosidases有二種,xylanases有二種,全部的酵素動力學均已完成,xylanases不對cellulose有作用,具備了造紙工業應用的初步條件。其中二種β-glucosidases為首次在T .harzianum中被純化出來,它們的specific activities為同類酵素中第三、第四高,為真菌中最高及次高。預計近期內撰文投稿。
7
利用β-glucosidases具有transglycosylation的作用,用以合成pentaose、hexose具有抑菌功能的oligosaccharide。
8
目前已純化分離出其他種黑殭菌素,繼續研究分析其化學及生物功能。
9
利用石英晶體微量天秤對微重量的敏感性,將二種登革熱單株抗體以不同的方法(glutaraldehyde、carbodiimide及protein A)固定於晶體表面製成登革熱免疫晶片,並分別以病毒培養液,模擬陽性檢體及臨床檢體作為樣品進行分析。結果顯此晶體能顯著的選別登革熱陽性與陰性,其對登革熱蛋白E及NS-1的偵測靈敏度達1.73μg/mL及0.74μg/mL. 此外亦製作兩種單株抗體結合的複合抗體免疫晶片,在以臨床檢體測試時亦呈現良好的辨識效果。此結果已為期刊Biosensors and Bioelectronics 發表(SCI, impact factor 3.5, top 10% in Biotechnology & Applied Microbiology category)。
