A recent systematic-phylogenetic reevaluation of Gram-positive bacteria with a base composition (G+C) of DNA higher than 50 mol% has led to the description of the class Actinobacteria (Stackebrandt et al., 1997) that embraces six orders. The order Actinomycetales (Buchanan 1917, emend Stackebrandt, Rainey and Ward-Rainey 1997) has been defined to include 10 suborders, one of which is Propionibacterineae, containing the family Propionibacteriaceae (Delwiche 1957, emend Rainey, Ward-Rainey and Stackebrandt, 1997) with the genera Propionibacterium (Orla-Jensen, 1909), Luteococcus (Tamura et al., 1994), Microlunatus (Nakamura et al., 1995) and Propioniferax (Yokota et al., 1994). Recently, four new genera have been added to the family, i.e., Friedmanniella (Schumann et al., 1997), Tessaracoccus (Maszenan et al., 1999b), Micropruina (Shintani et al., 2000) and Propionimicrobium (Stackebrandt et al., 2002; Table 1). As the majority of the recently described species ar ...
