　　据了解，该添加剂是由Komagataella phaffii DSM 33574以及贝莱斯芽孢杆菌DSM 21836和地衣芽孢杆菌ATCC 53757 的活孢子生产的。部分原文报道如下：

　　Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of the product EnzaPro co ntaining viable cells/spores of strains of Bacillus velezensis (DSM 21836) and Bacillus licheniformis (ATCC 53757) and an endo-1,4-��-xylanase produced by a genetically modified strain of Komagataella phaffii (DSM 33574) as a zootechnical additive in chickens for fattening, chickens reared for laying/breeding, turkeys for fattening, turkeys reared for breeding and minor poultry species for fattening or raised to the point of lay. The strains B. velezensis DSM 21836 and B. licheniformis ATCC 53757 were co nsidered to meet the qualified presumption of safety (QPS) requirements. The K. phaffii xylanase production strain is genetically modified. No viable cells and no recombinant DNA of the genetically modified production strain were detected in the final product. Therefore, the Panel co ncluded that the additive does not pose any safety co ncern regarding the xylanase production strain. EnzaPro is safe for all poultry species for fattening or reared to the point of lay at the proposed co nditions of use. The FEEDAP Panel co ncluded that the use of EnzaPro in animal nutrition is safe for the co nsumers and the environment. EnzaPro is not a skin irritant but should be co nsidered an eye irritant and a respiratory sensitiser. No co nclusions could be drawn on the potential of the additive to cause skin sensitisation. Due to the lack of data, the FEEDAP Panel could not co nclude on the efficacy of EnzaPro for the target species. EnzaPro is compatible with diclazuril, halofuginone and nicarbazin.
