2023年10月30日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就一種6-植酸酶（6-phytase）作為育肥雞、用于育肥的其它家禽或飼養用于產蛋和觀賞的鳥飼料添加劑的有效性發表科學意見。
據了解，這種6-植酸酶由Komagataella phaffii CGMCC 7.19產生。經過評估，專家小組得出結論，在擬議的使用條件下，該添加劑可能對目標物種有效。部分原文報道如下：
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.
