Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and the efficacy of the feed additives cellulase (produced by CBS 120604), beta-glucanase (produced by MUCL 39199) and xylanases (produced by MUCL 39203 and CBS 614.94) as silage additives for all animal species. In 2018, the FEEDAP Panel evaluated 11 enzymes to be used as silage additives. In that opinion, the additives, including the production strains, were characterised in full and their safety and efficacy were evaluated. However, the Panel could not conclude on the identification of the production strains of the xylanase produced by the strain with deposit number MUCL 39203 (product referred as to J) and the glucanase produced by strain with deposit number MUCL 39199 (product referred as to L). The Panel could not conclude either on the efficacy of the products J, L as well as for the cellulase produced by the strain with deposit number CBS 120604 (product referred as to H) and the xylanase produced by the strain with deposit number CBS 614.94 (product referred to as K). The newly submitted information showed that the species for the xylanase produced by the strain with deposit number MUCL 39203 (product J), should be changed into and that the species of the production strain for the glucanase produced by the strain with deposit number MUCL 39199 (product L), should be changed into . The Panel concluded that the four additives have the potential to reduce the protein degradation during the ensiling process when added at the corresponding inclusion levels in different types of forages.
应欧盟委员会的要求，欧洲食品安全局（EFSA）被要求就饲料添加剂纤维素酶（由CBS 120604生产）、β-葡聚糖酶（由MUCL 39199生产）和木聚糖酶（由MUCL 39203和CBS 614.94生产）作为所有动物物种青贮添加剂的安全性和有效性发表科学意见。2018年，饲料添加剂和动物产品中微生物小组评估了11种用作青贮添加剂的酶。在该意见中，对添加剂（包括生产菌株）进行了全面表征，并评估了它们的安全性和有效性。然而，小组无法就保藏编号为MUCL 39203的菌株所产木聚糖酶（产品称为J）和保藏编号为MUCL 39199的菌株所产葡聚糖酶（产品称为L）的生产菌株鉴定得出结论。小组也无法就产品J、L以及保藏编号为CBS 120604的菌株所产纤维素酶（产品称为H）和保藏编号为CBS 614.94的菌株所产木聚糖酶（产品称为K）的有效性得出结论。新提交的信息表明，保藏编号为MUCL 39203的菌株所产木聚糖酶（产品J）的物种应改为 ，保藏编号为MUCL 39199的菌株所产葡聚糖酶（产品L）的生产菌株物种应改为 。小组得出结论，当以相应的添加水平添加到不同类型的草料中时，这四种添加剂有可能减少青贮过程中的蛋白质降解。
