چکیده
|
Alphα-amylase was widely used in food industries,textile technology,paper manufacturing and so on. in this paper,the inducing mechanism of corn dextrins with different de values (dextrose equivalent value) on production of α-amylase by bacillus subtilis (b.subtilis) zjf-1a5 was investigated. the results showed that the yield of α-amylase by b.subtilis zjf-1a5 was increased by using dextrin with a certain de value range as carbon source,which could be attributed to the presence of oligosaccharide in dextrins. by ordinary fermentation with oligosaccharide as carbon source,it was found that the inducing activity of maltopentaose was the strongest. it could be confirmed that the dextrins played important roles during the process of production of α-amylase by b.subtilis zjf-1a5.
