EU Authorises L-Isoleucine Feed Additive Produced with Corynebacterium glutamicum for All Animal Species
The European Commission has formally authorised L-isoleucine produced by fermentation with the bacterial strain Corynebacterium glutamicum CCTCC M 2022764 as a zootechnical additive in animal feed for all species, under Implementation Regulation (EU) 2026/2087 dated 18 September 2026.
The European Commission has authorised a new L-isoleucine feed additive produced through fermentation with a specific bacterial strain, opening the ingredient to feed manufacturers across all EU member states for use in feed for all animal species.
Implementation Regulation (EU) 2026/2087, dated 18 September 2026, formally covers the authorisation. According to regulatory monitoring service Cambios Legales, the regulation authorises "L-isoleucine produced through fermentation with the bacterial strain Corynebacterium glutamicum CCTCC M 2022764 as a zootechnical additive in feed for all animal species."
L-isoleucine is an essential amino acid used in animal nutrition. The new authorisation allows feed manufacturers to incorporate this form of the amino acid — identified by its production organism and strain number — into compound feed and feed materials destined for any animal species in the EU.
The regulation is described as affecting feed manufacturers, animal feed additive producers, and livestock farmers operating within the EU. The full official title of the measure, as recorded in the Official Journal of the European Union, is: Reglamento de Ejecución (UE) 2026/2087 de la Comisión, de 18 de septiembre de 2026, relativo a la autorización de la l-isoleucina producida con Corynebacterium glutamicum CCTCC M 2022764 como aditivo para piensos destinado a todas las especies animales.
The regulation carries the CELEX identifier 32026R2087 and is published in the Official Journal of the EU (DOUE).
