(A) Two percent agarose gel electrophoresis of restriction fragments obtained by digestion of 16S rRNA gene products of Peptostreptococcus type strains with the restriction enzymes RsaI and CfoI. Lanes: 1, 11, and 21, 100-bp DNA ladder; 2, P. productus (RsaI); 3, P. prevotii (RsaI); 4, P. micros (RsaI); 5, P. magnus (RsaI); 6, P. anaerobius (RsaI); 7, P. asaccharolyticus (RsaI); 8, P. asaccharolyticus (RsaI); 9, P. indolicus (RsaI); 10, P. indolicus (RsaI); 12 to 20, same as lanes 2 to 10 but digested with CfoI. (B) Two percent agarose gel electrophoresis of restriction fragments obtained by digestion of 16S rRNA gene products of Peptostreptococcus type strains with the restriction enzyme HinfI. Lanes: 1 and 11, 100-bp DNA ladder; 2 to 10, as in Fig. 1A (lanes 2 to 10) but digested with HinfI. (C) Two percent agarose gel electrophoresis of restriction fragments obtained by digestion of 16S rRNA gene products of P. asaccharolyticus and P. indolicus type strains with the restriction enzyme MnlI. Lanes: 1, 100-bp DNA ladder; 2, P. asaccharolyticus; 3, P. indolicus.
