[Characterization of telluric bacteria attributable to Pseudomonas maltophilia].

The taxonomic position of some telluric non-fermenting Gram-negative bacteria collected into a phenon representing about a quarter of the soil isolates by an earlier numerical analysis is specified. The Shapiro--Chargaff coefficient determined by thermal-transition curves of the DNA and their hybridization by nitrocellulose filters method show a close affinity with Pseudomonas maltophilia.
