Ra. Rossellomora et al., BIOCHEMICAL AND CHEMOTAXONOMIC CHARACTERIZATION OF PSEUDOMONAS-STUTZERI GENOMOVARS, Journal of Applied Bacteriology, 76(3), 1994, pp. 226-233
A total of 48 strains representing the seven Pseudomonas stutzeri geno
movars (DNA/DNA homology groups) were studied for cellular fatty acid
composition, physiological characteristics and protein profiles. All s
trains were found to be homogeneous with respect to their fatty acid p
atterns. Numerical analysis of physiological properties demonstrated a
considerable phenotypic heterogeneity within the genomovars. Characte
rization of the individual genomic groups on the basis of biochemical
tests was not possible. In a numerical study of cellular protein patte
rns, two main clusters were obtained, one representing genomovars 1, 6
and 7 characterized by a high G + C content (mean value > 64 mol%), t
he other representing genomovars 2, 3, 4 and 5 with a low G + G conten
t (< 64 mol%). The standardized cellular protein patterns have potenti
al for differentiation of the genomic groupings within the species Ps.
stutzeri as currently circumscribed.
