Result3 strains of endophytic fungi had growth peak when the pH value was 6.5-7.5,and could grow within pH of 4.0-8.5. Their acid-alkali adaptability was strong,in which the P-3 adaptability was the strongest. P-1and P-2 had the stronger inhibition to the Bacillus subtilis,Escherichia coli and Staphylococcus aureus,and P-3 only had the little inhibition to Escherichia coli. The 3 endophytic fungi all had inhibitory effect on Podosphaera leucotrlcha,Alternaria mali,and Gymnosporangium yamadae Miyabe,in which,P-1 had the better inhibitory ability.

结果3株内生真菌在pH值6.5～7.5出现生长最高峰，在pH值4.0～8.5都可以生长，酸碱适应性很强，其中P-3的适应性最强。P-1和P-2对枯草芽孢杆菌、大肠杆菌、金黄色葡萄球菌都有较强的抑制能力，而P-3只对大肠杆菌有很微弱的抑制能力。3株内生真菌对苹果锈病病原菌、苹果白粉病病原菌、苹果落叶病病原菌都有抑制作用，其中P-1的抑制能力较强。

The molecular sieve is prepared in the steps: at the room temperature, hexadecyl trimethyl ammonium bromide is mixed and dissolved with the sodium hydroxide, and is added with TEOS in dropping way, and simultaneously added with Me metal salt water solution and lanthanum nitrate solution in dropping way; the pH value of the mixed solution is adjusted by acetic acid to be 10 to 11, and is mixed for 1 to 2 hours after being stabilized; the sol is moved into a polyfluortetraethylene bottle to be heated and crystallized for 2 days in the oven at the temperature of 100 DEG C; after filtering, washing and drying for nights, and being calcined in a muffle at the temperature of 550 DEG C for 3 to 7 hours, the dual-metal-atom improved MCM-41 mesoporous molecular sieve is obtained.

该分子筛的制备为室温下，将十六烷基三甲基溴化铵和氢氧化钠混合溶解，搅拌并滴加入TEOS，同时滴加入Me金属盐水溶液和硝酸镧溶液并搅拌，用乙酸调节pH值至10～11，稳定后搅拌1～2小时，溶胶转入聚四氟乙烯瓶中在100℃下烘箱水热晶化2天，经过滤、洗涤、干燥过夜，马弗炉550℃焙烧3-7h，得双金属原子改性MCM-41介孔分子筛产品。

MIPC was photocatalytically transformed to 3,4-dihydroxyl hypnone, 2-iso-butyl phenol and acetic acid, and mineralized ultimately in oxygenated TiO2 slurries. The photocatalytic degradation processed according to first order kinetics with the apparent rate constant depending on initial concentration, light intensity and the amount of catalyst. The amount of catalyst had an optimum value (0.5g/L). The apparent rate was inversely proportional to square root of the initial concentration approximately.
