dextrin

 [dek´strin]
any of a range of glucose polymers of varying sizes formed during the hydrolysis of starch.

dex·trin

(deks'trin),
A mixture of oligo(α-1,4-d-glucose) molecules formed during the enzymic or acid hydrolysis of starch, amylopectin, or glycogen; on further hydrolysis they are converted into d-glucose. Dextrins are of much lower molecular weight than dextrans, hence not suitable as plasma expanders; dextrin (usually white dextrin) is used in pharmaceutical preparations.
Synonym(s): starch gum

n.
Any of various soluble polysaccharides obtained from starch by the application of heat or acids and used mainly as adhesives and thickening agents.

In Fig.2, the neutral amylase became strong noticeably when starch and other three dextrins were taken as carbon source.
Howerer, in our study, the difference of protease activity produced by different carbon sources is not significant, and the protease activity by the dextrins which produce higher amylase activity is higher than the control samples which have lower amylase activity.
