Effectiveness of new enzymatic preparations obtained from modified organisms

Efficiency of enzyme action on starch was tested. The following enzymatic preparations were used: AMG 300L and AMG E -glucoamylase, Dextrozyme 225/75L and Dextrozyme E -combination of glucoamylase and pullulanase, Promozyne 200L -pullulanase. Maltodextrine, wheat and tapioka starches were used as a...

Summary:Efficiency of enzyme action on starch was tested. The following enzymatic preparations were used: AMG 300L and AMG E -glucoamylase, Dextrozyme 225/75L and Dextrozyme E -combination of glucoamylase and pullulanase, Promozyne 200L -pullulanase. Maltodextrine, wheat and tapioka starches were used as a substrate. The tested enzymatic preparations were applied for saccharification individually or in combination. Research was carried out fixed parameters: temperature, pH, starch concentration and enzyme dosage. The research indicated that the enzymatic preparations obtained from genetically modified microorganisms characterized higher efficiency. Application in similar dosage of Dextrozyme E instead of AMG 300 makes possible to obtain hydrolyzates with higher DE by 16-32 percent or to produce hydrolyzates with similar DE within 24 h
