據(jù)了解，L-賴氨酸硫酸鹽是由谷氨酸棒桿菌 KFCC 11043經(jīng)發(fā)酵制成的添加劑。經(jīng)過評(píng)估，專家小組認(rèn)為該添加劑對(duì)目標(biāo)物種、消費(fèi)者和環(huán)境是安全的。L-賴氨酸硫酸鹽被認(rèn)為是非反芻動(dòng)物物種必需氨基酸L-賴氨酸的有效來源，為了使補(bǔ)充的L-賴氨酸對(duì)反芻動(dòng)物和非反芻動(dòng)物一樣有效，需要防止其在瘤胃中降解。部分原文報(bào)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 sulfate produced by fermentation using Corynebacterium glutamicum KFCC 11043 when used as a nutritional additive in feed for all animal species. The active substance is l ‐lysine. The production strain qualifies for the qualified presumption of safety （QPS ） approach to safety assessment and was not detected in the final product. l ‐Lysine sulfate produced using C. glutamicum KFCC 11043 does not pose any safety concern associated with the production strain. l ‐Lysine sulfate produced by C. glutamicum KFCC 11043 is considered safe for the target species. When using l ‐lysine sulfate, the background sulfur/sulfate content in the compound feed should be taken into account. l ‐Lysine sulfate produced by C. glutamicum KFCC 11043 is safe for the consumer and for the environment. From the results of studies on the safety for the user of l ‐lysine sulfate produced by a different production strain, it was possible to conclude on the safety for the user of the product under assessment. l ‐Lysine sulfate produced by C. glutamicum KFCC 11043 is considered non‐toxic by inhalation, non‐irritant to skin or eyes and it is not a skin sensitiser. l ‐lysine sulfate 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.
