Ga. Dykes et al., PLASMID PROFILES OF LACTIC-ACID BACTERIA ASSOCIATED WITH VACUUM-PACKAGED VIENNA SAUSAGE MANUFACTURE AND SPOILAGE, Letters in applied microbiology, 17(4), 1993, pp. 182-184
Plasmid profiles of lactic acid bacteria from spoiled vacuum-packaged
vienna sausages (61) and the corresponding manufacturing environment (
50) were determined to assess the use of this technique for pinpointin
g sources of spoilage populations. Although plasmids were present in >
60% of the strains, no profiles were common to these two groups. The o
ccurrence of specific individual plasmids in several isolates from the
spoilage population may, however, be useful in diagnosing the spoilag
e potential of individual strains.
