摘要
用适当的次声频率和声压来处理黑曲霉孢子（微生物），能使其柠檬酸率增加７％左右，同时用磁场和低频磁场作对比处理，其结果亦同。此外，用此类方法处理五种生物酶和蒸馏水时，其紫外光谱的特征蜂的吸光值均有所增加，与增加酶在缓冲剂中的浓度或水的温度作用相同。而在用此二法处理黑曲菌孢子的发酵液时，发现其主酶（α—淀粉酶）的活力及菌丝体重量也对应地增加，和用同法处理此类纯酶时其活力不能增加的一些报道加以对比。
Infrasound and magnetic field are used to treat Aspergillus Niger. And we find that the production rate of critic acid, the activity of enzyme and the weight of hypha are all increased at the same rate. Also,these two methods are used to treat some enzymes and distilled water and we get an increase in absorbands of UV spectra of them, similar to the effects obtained, by increasing the concentration of onzymes or by increasing the temperature of water.
