为了阐明对有机氯农药氯丹具有高效降解能力的白腐菌Phlebia brevispora的酶促降解特性及规律,在实验室条件下,菌株经过纯培养、超声波破碎和高速离心等过程,提取到胞内粗酶液和胞外粗酶液,研究了降解酶对氯丹的降解及其转化特性。结果显示,处理20min后,胞内酶及胞外酶对10μmol/L氯丹的降解率分别达到33.2%和10.4%。氯丹胞内酶降解的酶促反应最适温度是32℃,最适pH5.0,最适条件下反应1h后的氯丹降解率为49.9%。胞内酶在25～40℃,pH4.5～6.0范围内均具有较高的降解活性;胞内粗酶液的米氏常数Km为3.49μmol/L,最大反应速率Vmax为8.38μmol/min。在胞内酶及胞外酶培养体系分别检测到完全不同的代谢产物。结果表明,氯丹降解酶系包括胞外酶和胞内酶,其中胞内酶是主要降解酶。胞外酶主要催化氯丹的脱氢和脱氯化氢反应,而胞内酶则主要通过羟基化和置换反应将氯丹转化为一些羟基化产物。

We simultaneously observed both the fast proton generation and terahertz(THz) radiation in the laser pulse interaction with a thin-foil target. The maximum proton energy of ～2.3 Me V and an intense THz radiation were observed at the pulse duration of～30 fs. We also measured the proton beam and UV harmonics from a thin-foil target by changing the laser pulse duration. In the case of the ～500 fs, peaks of UV harmonics up to fourth order appeared. This unique combination of the multiple beams will provide useful applications such as pump-probe experiments.
