“…The genus Corynebacterium belongs to the group of actinomycetes that includes the CMN group (Corynebacterium, Mycobacterium, Nocardia and Rhodococcus species) (Hard, 1969;Songer et al, 1988;Songer, 1997;Paule et al, 2004;Dorella et al, 2006a). These Grampositive bacteria constitute a very heterogeneous group that shares particular characteristics, such as a specific cell wall organization (Hard, 1975;Funke et al, 1995;Collins et al, 1982Collins et al, , 1998Connor et al, 2000;Bayan et al, 2003;Hall et al, 2003;Dorella et al, 2006a) and high G + C content (47-74%) (Garg et al, 1985;Goodfellow, 1989;Funke et al, 1995;Navas, 1996;Dorella et al, 2006a).…”
