Raw corn starch granules were hydrolysized by glucoamylase in a chemostat. The hydrolysis of three different-sized granules shows that smaller granules undergo more hydrolyzation than larger ones. After 78 h, 97% of the granules was hydrolysized with diameter between 0.15 mm and 0.3 mm at 50℃. When corn starch concentration increased from 100 g/L to 250 g/L, the amount of reducing sugar produced was proportional to the initial substrate concentration and no substrate inhibition phenomenon appeared. In order to study the product inhibition exactly, the product from hydrolysis reaction itself was added into the hydrolysis system at the beginning of starch hydrolysis.Product inhibition with different quantities of product added were studied in the initial several hours,during which period enzyme inactivation could be neglected and product inhibition could be studied separately. The experiments indicate that product inhibition happens when the additional quantity exceeds 9.56 g/L. 相似文献

Marangoni effectis of interestto the chemical en-gineers from both scientific and practical points ofview[1—6]. The Marangoni convection contributes tothe renewal of the interfacial surface and is capable ofincreasing the mass transfer rate, resulting in intensi-fication of separation processes such as distillation,extraction, absorption, and desorption. The theoretical studies of Marangoni instability inthe past were focused on determining the critical tran-sition point. The critical condit… 相似文献

“只有科学是真学问”这样的话,在毛泽东的文稿中是空前绝后的,因为毛泽东历来爱看历史小说、笔记小说、哲学等书,但这句话确是毛泽东在信中对儿子说的。仅就父亲对儿子这种关系讲,自然决不是违心的话。我们不妨先来看看他给儿子的这封信。这是1941年1月31日写给毛岸英、毛岸青兄弟二人的。 很早以前,接到岸英的长信,岸青的信,岸英寄来的照片本,单张相片,并且是几次的 相似文献
