據(jù)了解，這種6-植酸酶是由里氏木霉CBS 126897生產(chǎn)的。經(jīng)過(guò)評(píng)估，專(zhuān)家小組認(rèn)為在建議的使用條件下該添加劑對(duì)目標(biāo)物種和環(huán)境是安全的。該添加劑在500 FTU/千克全價(jià)飼料的使用水平下對(duì)鮭魚(yú)和觀賞魚(yú)是有效的，在2500 FTU/千克全價(jià)飼料的使用水平下對(duì)其他有鰭魚(yú)類(lèi)是有效的。部分原文報(bào)道如下：

 

　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of 6-phytase (Quantum® Blue) as a zootechnical feed additive for fin fish. The additive is authorised for use in poultry and pigs. The additive is available in solid and liquid forms, and the 6-phytase contained in the product is produced by fermentation with a genetically modified strain of Trichoderma reesei. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the genetic modification of the production strain does not give rise to safety concerns; viable cells of the production strain and its DNA were not detected in the final products. The FEEDAP Panel concluded that, based on the data available, the additive tested is safe for fin fish at the highest recommended level of 2500 phytase activity unit (FTU)/kg complete feed. The Panel concluded that Quantum® Blue is not an irritant to skin and eyes nor a skin sensitiser. Owing to the proteinaceous nature of the active substance, 6-phytase (Quantum® Blue) is considered a respiratory sensitiser. The use of Quantum® Blue as a feed additive is considered safe for the environment. The additive is considered to be efficacious as a zootechnical additive for salmonids and ornamental fish at 500 FTU/kg complete feed and other fin fish at 2500 FTU/kg complete feed.
