Safety evaluation of the food enzyme phospholipase D from the genetically modified Streptomyces violaceoruber strain pPDN

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract The food enzyme phospholipase D (phosphatidylcholine phosphatidohydrolase; EC 3.1.4.4) is produced with the genetically modified Streptomyces violaceoruber strain pPDN by Nagase ChemteX. The production strain of the food enzyme contains several antimicrobial resistance genes, of which at least one is acquired.
