Identification and characterisation of staphylococci isolated from PDO salsiccia, soppressata and capocollo di Calabria

摘要

Seventy-eight strains of Gram-positive, cataiase-positive and iysostaphin-sensitive cocci were isolated from Calabria DPO sausages and identified. All strains belong to genus Staphylococcus; 62.8% was identified as S. xylosus; 59% of S. xylosus isolates grows at pH of 5.1 and at 15°C. Most strains do not metabolise throat fat but do carry out tributyrin lysis. Thirty-one isolates out of 34 tested reduce nitrates under pH, temperature and lactic acid level similar to those found during production.
