The production strain of the food enzyme fulfils the requirements for the qualified presumption of safety approach to safety assessment. Consequently, in the absence of other concerns, the Panel considered that toxicological studies were not needed for the safety assessment of this food enzyme. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and two matches with respiratory allergens were found. The Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme cannot be excluded (except for the production of distilled alcohol), but the likelihood is low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Taxonomic identity of the Bacillus licheniformis strains used to produce food enzymes evaluated in published EFSA opinions.

Bacillus paralicheniformis, a species known to produce the antimicrobial bacitracin, could be misidentified as Bacillus licheniformis, depending on the identification method used. For this reason, the European Commission requested EFSA to review the taxonomic identification of formerly assessed B. licheniformis production strains. Following this request, EFSA retrieved the raw data from 27 technical dossiers submitted and found that the taxonomic identification was established by 16S rRNA gene analyses for 15 strains and by whole genome sequence analysis for 12 strains. As a conclusion, only these 12 strains could be unambiguously identified as B. licheniformis.
