Речь идет и биотехнологическом производстве аминокислот.

According to regulation 1169120lI, carriers and carry-overs used during manufacturing process of amino acids
defined as .,ingredients" acids and derivatives and therefore will fall under the scope of EU GMO
regulations i.e. under manufactured and/or requirements for GMOs authorization and labelling.

В тексте указанного постановления ЕС не нашла никакого упоминания carriers and carry-overs.
У меня есть некоторые предположения, что carryovers - это некие белки трансмембранного переноса, участвующие в переносе продукта реакции против градиента концентраций, как описано, например, здесь:

In 1996, the gene encoding a membrane protein involved in the active export of lysine– lysE – was cloned and sequenced. It is responsible for exporting lysine up a concentration gradient eventually leading to the accumulation of as much as 1 mole per liter of lysine. Mutations in this gene cause lysine to accumulate in the cytoplasm but not in the extracellular medium. Introducing the gene into a multi-copy plasmid in C. glutamicum leads to increases in the rate of efflux of intracellular lysine.

Но что такое carriers?
Буду рада любой помощи.
