چکیده مقاله
Beta glucan found in cereals is a non nutrient for poultry that would cause some digestion problems Betaglucanasecan break down the beta glucan in cereals and make it easier to digest In this study, the starch inwheat bran was removed For the first time, the beta glucanase was produced by solid state cultivation ofAspergillus niger CCUG33991 on starch free wheat bran without adding any nutrients The influence of thiseconomical enzyme extract on structure was investigated for the two kinds of cereals Enzyme solution had863 4 units of beta glucanase activity per gram of dry substrate U/gds De starching from wheat branincreased beta glucanase production Treatment of cereal particles with the extract modified their surfacesand made them more vulnerable to attack by digestive enzymes The study demonstrated that beta glucanasemay be a profitable animal feed additive especially for the feeds with high beta glucan content grains
