The potential to produce biogenic amines was investigated for 56 coagulase-negative staphylococci isolated during industrial Spanish dry-cured ham processes. The presence of biogenic amines from bacterial cultures was determined by thin-layer chromatography. The percentage of strains that decarboxylated amino acids was very low (3.6%). The only staphylococci with aminogenic capacity were an his...

The complete sequence of rpoB, the gene encoding the beta subunit of RNA polymerase was determined for Staphylococcus saccharolyticus, Staphylococcus lugdunensis, S taphylococcus caprae, and Staphylococcus intermedius and partial sequences were obtained for an additional 27 Staphylococcus species. The complete rpoB sequences varied in length from 3,452 to 3,845 bp and had a 36.8 to 39.2% GC con...
