Over the years, species of the genus have been reclassified
and revised several times (Sneath et al., 1981; Oyaizu &
Komagata, 1983; Vancanneyt et al., 1996; Anzai et al.,
2000). Members of the genus Pseudomonas are widely
distributed in soil, water, air, plants and many other
natural habitats (Palleroni, 1992)
