H. Mordarska et M. Pasciak, A SIMPLE METHOD FOR DIFFERENTIATION OF PROPIONIBACTERIUM-ACNES AND PROPIONIBACTERIUM-PROPIONICUM, FEMS microbiology letters, 123(3), 1994, pp. 325-329
TLC glycolipid profiles of several culture collection and clinical str
ains of Propionibacterium acnes and Propionibacterium propionicum were
examined. The former were characterized by weak orcinol-positive mino
r glycolipids of type g, while the others had mainly strong orcinol-po
sitive major glycolipids of type G. The simple and rapid small scale p
rocedure seemed to be useful for differentiation of these phenotypical
ly similar and genotypically closely related species irrespective of t
heir serotypes.
