An adapted isolation procedure reveals Photobacterium spp. as common spoilers on modified atmosphere packaged meats

This study employed a comparative isolation approach of Photobacterium spp. and aimed to develop an adapted isolation procedure for recovery from food samples, as demonstrated for different meats: Marine broth is used for resuspending and dilution of food samples, and cultivation on marine broth agar supplemented with meat extract and vancomycin at 15 °C for 72 hours. Identification of spoilage‐associated microbiota was carried out via MALDI‐TOF MS using a database supplemented with additional mass spectrometry profiles of Photobacterium spp. This study provides evidence for the common abundance of multiple Photobacterium (P.) species in relevant quantities on various modified atmosphere packaged (MAP) meats. P. carnosum was predominant on beef and chicken, while P. iliopiscarium represented the major species on pork and P. phosphoreum on salmon, respectively. This article is protected by copyright.
