Abstract
The soluble cellular proteins of strains of P. magnus and P. micros were examined by polyacrylamide gel electrophoresis. The protein patterns were distinctive and repeatable and the 2 spp. could be separated readily. The protein pattern of strain ATCC 23195, the type strain of P. glycinophilus (Cardon and Barker 1946) Douglas 1957, was identical to that of strain ATCC 33270 (= VPI 5464), the type strain of P. micros (Prevot 1933) Smith 1957. Because these 2 strains were 84% homologous as determined by DNA-DNA homology experiments, the name P. glycinophilus is a later subjective synonym of P. micros. Preliminary results indicated that Peptococcus variablis (Foubert and Douglas 1948) Douglas 1957 may be a valid species, but reinstatement is not proposed at this time.
