據(jù)條例，這種L-賴氨酸濃縮液體和L-賴氨酸鹽酸鹽由谷氨酸棒桿菌KCCM 80216發(fā)酵產(chǎn)生。經(jīng)過評估，專家小組認(rèn)為該添加劑對所有動物物種、消費者和環(huán)境是安全的。L-賴氨酸濃縮液體和L-賴氨酸鹽酸鹽被認(rèn)為是非反芻動物物種必需氨基酸L-賴氨酸的有效來源。為了使補(bǔ)充的賴氨酸對反芻動物和非反芻動物同樣有效，需要防止其在瘤胃中降解。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 the safety and efficacy of concentrated liquid l‐lysine (base, minimum 50%) and l‐lysine monohydrochloride (HCl, minimum 99%) produced by fermentation with a genetically modified strain of Corynebacterium glutamicum (KCCM 80216) as nutritional additives for all animal species. Neither the production strain nor its recombinant DNA was detected in the final products. The additives do not pose any safety concern associated with the genetic modification of the production strain. Concentrated liquid l‐lysine (base) and l‐lysine HCl produced by C. glutamicumKCCM 80216 do not represent a risk for the target species, the consumer and the environment. From the results of studies on the safety for the user of concentrated liquid l‐lysine (base) and l‐lysine HCl produced by a different production strain, it was possible to conclude on the safety for the user of the products under assessment. The concentrated liquid l‐lysine (base) and the l‐lysine HCl are not irritant to skin or eyes or skin sensitiser. l‐lysine HCl is not hazardous by inhalation. l‐lysine HCl and concentrated liquid l‐lysine (base) are considered as efficacious sources 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.
