🧀 3 concerned cheese(s) & family(ies)  •  🦠 1 linked living taxon(s)

🔍 Clinical, Sensory & Functional Diagnosis

Alvéoles gazeuses précoces à intermédiaires, fentes internes (slits), bombement des emballages et goût acide-vinaigré

🧬 Biochemical, Enzymatic & Genetic Mechanism

Voie de la 6-phosphogluconate/phosphocétolase convertissant le glucose et le galactose en lactate, éthanol/acétate et CO2, plus hydrolyse de l'arginine (voie ADI : NH3 + CO2)

🌡️ Physicochemical Parameters & Target Matrices

Fin de pressage et première moitié d'affinage (2 jours à 6 semaines) • Thermorésistance au chauffage en cuve et au filage (croissance jusqu'à 45 °C), présence de galactose résiduel et d'arginine

🛡️ Cellar Protocol, Prophylaxis & Biocontrol

Utilisation de levains Streptococcus thermophilus Gal-positifs, maîtrise du refroidissement après filage ou pressage et hygiène des saumures/moulages
