Abstract

A numerical analysis based on 231 phenotypic characteristics was performed with 100 isolates from 4 natural mineral waters so as with forty-nine type or collection strains belonging or related to fluorescent Pseudomonas strains. Since this study has been the continuation of a previously published work (ELOMARI et al., 1995) seven strains from the two former phenotypic groups Ia or IIb were included among the type orcollection strains which have been used before in order to make easier the link with the two studies. The data were processed by the Dice similarity coefficient and unweighted pair group algorithm with arithmetic averages as well. Eight clusters (IX to XV, III) were defined at the 58% similarity level. Clusters XII, XIII, XIV and XV were further divided into 18 subclusters. Type and collection strains clustered intoeight groups which correlated closely with those generated by the previous numerical analysis (Ia, Ic, IIb, III, IVa, IVb, IVc, VII). The three phenotypically characterized groups of mineral water strains Ib, IIa and V were also defined again. Furthermore most of the isolates ofthe present study, fell into four new groups which did not include any type or collection strains: IX (10 strains), XIIIb (12 strains), XIIIc (9 strains), XVa (9 strains). Later on DNA/DNA hybridization studies would be necessary to specify the taxonomic status of these four groups within the genus Pseudomonas.
