2020427日,據(jù)歐盟食品安全局(EFSA)消息,應(yīng)歐盟委員會的要求,歐盟動物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就轉(zhuǎn)基因谷氨酸棒桿菌(Corynebacterium glutamicumDSM 32932發(fā)酵生產(chǎn)的L-賴氨酸鹽酸鹽(L-Lysine Monohydrochloride)作為所有動物物種添加劑的安全性和有效性發(fā)表科學(xué)意見。

經(jīng)過評估,專家小組認(rèn)為該添加劑對目標(biāo)物種、消費者和環(huán)境都是安全的,是非反芻動物賴氨酸的有效來源。

部分原文報道如下:

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on l‐lysine monohydrochloride produced by fermentation with the genetically modified strain of Corynebacterium glutamicum DSM 32932. Neither the production strain nor its recombinant DNA were detected in the final product. The additive does not pose any safety concern associated with the genetic modification of the production strain. l‐Lysine HCl produced by C. glutamicum DSM 32932 is considered safe for the target species, for the consumer and for the environment. l‐Lysine HCl produced by C. glutamicum DSM 32932 is not toxic by inhalation; it is not irritant to skin and not a skin sensitiser. The additive is not corrosive to eyes but it should be considered as an eye irritant. In general, l‐lysine HCl is considered as an efficacious source of the essential amino acid l‐lysine for non‐ruminant animal species. For the supplemental l‐lysine to be as efficacious in ruminants as in non‐ruminant species, it would require protection against degradation in the rumen.
