据了解,这种6-植酸酶是由里氏木霉CBS 126897生产的。经过评估,专家小组认为在建议的使用条件下该添加剂对目标物种和环境是安全的。该添加剂在500 FTU/千克全价饲料的使用水平下对鲑鱼和观赏鱼是有效的,?500 FTU/千克全价饲料的使用水平下对其他有鳍鱼类是有效的。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 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 co
ntained 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) co
ncluded 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 co
ncluded that, ba
sed 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 co
ncluded 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 co
nsidered a respiratory sensitiser. The use of Quantum
?Blue as a feed additive is co
nsidered safe for the environment. The additive is co
nsidered to be efficacious as a zootechnical additive for salmo
nids and ornamental fish at 500 FTU/kg complete feed and other fin fish at 2500 FTU/kg complete feed.
