The high inoculum levels increased the bacterial growth and shorten the time for antifungal substance production. The powder of rice, soybean cake, yeast, and wheat bran, CaCO3 and KH2PO4 were better nutrients for the bacteria growth and antifungal substance production. There were two stages during the fermentation process at 30℃. The growth of bacteria increased at the first 24 h and the pH of broth rose, but no antifungal activity was observed until 41 h later and reached to the highest level at 114 h.

The effect of zeolites ion-exchanged by transition metals on thermal catalytic cracking reaction is studied. The product distributions of the cracking reactions catalyzed by theβor ZSM-5 zeolites exchanged with transition metals are different from that catalyzed by corresponding Hzeolites, which means the mechanism of cracking reactions has varied. Group Ⅷ metals Fe, Co, Ni and Cu, Zn are shown to be of strong catalytic activity of oxidative dehydrogenation, while Ti and Cr are not of oxidative activity. Catalyzed by zeolites or catalyst containing Ag, conversion of thermal catalytic cracking reactions and the yield of ethylene increase while the yield of propylene does not decrease. Silver can not only promote the formation of carbonium ion, but also convert carbonium ion into free-radical via redox reaction. The weak adsorption of olefins on silver reduces the occurrence of hydrogen transfer and dehydrogenation. As a result, the yield of light olefins is favored by silver in the catalyst.

采用过渡金属交换的分子筛作为催化剂,进行催化热裂解制取乙烯的反应,研究发现,在β沸石分子筛和ZSM-5分子筛中引入过渡金属后,催化热裂解反应的产物分布与相应的氢型分子筛相比有了较大的变化,说明过渡金属的加入对于催化热裂解反应的机理具有影响,Ⅷ族金属如Fe、Co、Ni和第Ⅰ、Ⅱ副族Cu、Zn表现出较强的氧化脱氢活性,产物中氢气、焦炭的产率很高,Ti、Cr则未表现出氧化作用:分子筛及催化剂中引入银后,催化热裂解反应的转化率和乙烯的产率有了提高,丙烯产率没有很大的变化,说明银在催化热裂解反应中能够促进正碳离子的生成,又有可能通过氧化-还原作用部分改变反应机理,促进了自由基的生成,并且由于银对烯烃的吸附很弱,其氢转移反应和脱氢、加氢活性比较低,有利于烯烃产率的提高。
