Safety and efficacy of l‐lysine monohydrochloride and concentrated liquid l‐lysine (base) produced by fermentation using Corynebacterium glutamicum strain KCCM 10227 for all animal species

Abstract

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 and concentrated liquid l‐lysine (base) produced using Corynebacterium glutamicum KCCM 10227 when used as nutritional additives in feed and water for drinking for all animal species. The active substance is l‐lysine. l‐lysine HCl and concentrated liquid l‐lysine (base) produced by the strain C. glutamicum KCCM 10227 do not represent a risk for the target species, the consumer and the environment. l‐lysine HCl produced by C. glutamicum KCCM 10227 is hazardous by inhalation, it is not irritant to skin but mildly irritant to eyes and it is not a skin sensitiser. Concentrated liquid l‐lysine (base) produced by C. glutamicum KCCM 10227 is hazardous by inhalation, not irritant to skin and eyes and it is not a skin sensitiser. 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.
