Abstract.
Streptomycetes were constantly recovered from surface-
sterilised roots of 156 plant species. Following a grouping of
the isolate population (1422 strains), a more detailed
characterisation was carried out on 82 representative
isolates. Identification by probabilistic methods showed the
predominance of three Streptomyces clusters, namely
S.anulatus, S.halstedii and S.albidoflavus, and allowed a
physiological characterisation of the streptomycete population
inhabiting plant roots.
