α-环糊精葡萄糖基转移酶菌株的筛选与鉴定
Selecting and identification of the producing strain for α-Cyclodextrin Glycosyltransferase
摘要
Abstract
22 strains of bacteria which could yield α-CGTase were prescreened from soil simples. These soils are rich in starch. 3 strains of them with higher enzymatic activity were further selected by assaying transparent zone. Finally, we obtained a strain with activity of 0. 86 U/mL from setting up a standard curve of enzymatic activity. This research showed that N1 was a Klebsiella oxytoca based on its colony morphology, microscopic observation and physiology and biochemical characteristic.关键词
