2023年10月30日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就一种6-植酸酶（6-phytase）作为育肥鸡、用于育肥的其它家禽或饲养用于产蛋和观赏的鸟饲料添加剂的有效性发表科学意见。
据了解，这种6-植酸酶由Komagataella phaffii CGMCC 7.19产生。经过评估，专家小组得出结论，在拟议的使用条件下，该添加剂可能对目标物种有效。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of 6-phytase produced by Komagataella phaffii CGMCC 7.19 (Nutrase P) as a zootechnical feed additive for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds. In a previous opinion, the FEEDAP Panel concluded on the efficacy of Nutrase P for the target species at the level of 1,500 phytase units (FTU)/kg but could not conclude at the minimum recommended use level of 500 FTU/kg complete feed. The applicant has provided supplementary information, consisting in the statistical re-analysis of the long-term study assessed in the original opinion, in order to support the efficacy of the additive at the minimum recommended level of 500 FTU/kg complete feed. Considering the previously submitted studies and the re-analysis of the long-term study, the Panel concluded that the additive has a potential to be efficacious for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds under the proposed conditions of use.
