Safety evaluation of the food enzyme subtilisin from the non‐genetically modified Bacillus paralicheniformis strain DP‐Dzx96

Abstract The food enzyme subtilisin (serine endopeptidase, EC 3.4.21.62) is produced with the non‐genetically modified Bacillus paralicheniformis strain DP‐Dzx96 by Genencor International B.V. The food enzyme was considered free from viable cells of the production organism. The food enzyme is intend...

Description
Summary:Abstract The food enzyme subtilisin (serine endopeptidase, EC 3.4.21.62) is produced with the non‐genetically modified Bacillus paralicheniformis strain DP‐Dzx96 by Genencor International B.V. The food enzyme was considered free from viable cells of the production organism. The food enzyme is intended to be used in five food manufacturing processes: production of protein hydrolysates from plants and fungi, production of protein hydrolysates from meat and fish proteins, production of cooked rice, production of modified meat and fish products, and yeast processing. The production strain of the food enzyme contains known antimicrobial resistance genes. Bacitracin, a medically important antimicrobial, was detected in the food enzyme. The presence of bacitracin represents a risk for the development of antimicrobial resistant bacteria. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and three matches with respiratory and two matches with food allergens were found. The Panel considered that, under the intended conditions of use, the risk of allergic reactions upon dietary exposure to this food enzyme, particularly in individuals sensitised to muskmelon or pomegranate, cannot be excluded, but would not exceed the risk of consuming these foods. Due to the presence of bacitracin, the Panel concluded that the food enzyme subtilisin produced with the non‐genetically modified Bacillus paralicheniformis strain DP‐Dzx96 cannot be considered safe.
