Among the 68 isolates, selected from 13 raw-milk samples in Finland (that originate from farm, truck or silo tanks), 60 (88%) were psychrotrophs. All the isolates were characterized by the determination of their spoilage and phenotypic features: proteolytic and lipolytic activities, the production of lecithinases and hemolytic factors were considered. Phenotypic characterization of the isolates was mainly performed with API 20NE and BIOLOG GN2 identification systems; the results were system-dependent, although the presence of representatives of the Pseudomonas genus (for the majority of the isolates) was suggested by both systems. The results of the numerical profile analyses by API 20NE proposed that some strains might be members of Stenotrophomonas, Burkholderia and Acinetobacter genera; however, the identity of many isolates remained doubtful or controversial.
