Abstract.
A computer assisted probabilistic identification system was
used to identify 7 species of Streptomyces, characterised by
high extracellular protease activity, which were isolated from
different ecosystems. The probability matrices for major and
minor clusters using 25 and 28 phena respectively were
provided by MICRO-IS. Sixty-three morphological, physiological
and biochemical tests were used and the results quantified in
probability terms. Out of the 7 isolates, 5 were identified as
Streptomyces diastaticus, S.anulatus, S.albidoflavus (2
strains) and S.exofoliatus and the remaining 2 to the minor
clusters as S.misakiensis and S.longisporoflavus, all with a
score of 0.9900 to 0.9343.
