High performance liquid chromatography (HPLC) analysis was applied for determination of guanine plus cytosine (G + C) contents of DNA of Butyrivibrio fibrisolvens. By values of G + C contents, a reference strain and 20 wild strains of B. fibrisolvens were classified into at least two distinct subgroups, i.e. G + C contents of 18 strains were 38-40 mol% and those of 3 strains including the reference strain were 43-45 mol%. Clear relationships were not observed between G + C contents and biological properties of 21 strains of B. Fibrisolvens.
