✦ Synopsis

Determination of the primary structure of the peptidoglycan of 8 strains of Peptococcus showed that 4 different peptidoglycan types occur. P. prevotii ATCC 9321 and P. grigoro]]ii tt4O/10 contain the L-Lys-D-Glu type with glycine in position 1 of the peptide subunit. _P. variabilis ATCC 14955 and H 39/5, P. activus H22/12 and _P. anaerobius It/7 show the L-Lys-Gly type with glycine in position 1 of the peptide subunit. P. aerogenes ATCC 14963 contains the L-Orn-D-Glu type and P. 8accharolyticus ATCC 14953 the L-Lys-Gly 4, T.-Serltype. The occurrence of these different peptidoglycan types is a valuable criterion for the classification of peptococci. The following conclusions were made: P. saccharolyticus had to be excluded from Peptococcus. P. variabilis and P. anaerobius c~n be united within one species, whereas P. prevotiiATCC 9321 andP. aerogenes ATCC 14963 can not be included in one species as has been suggested before. P. grigoro]]ii It40/10 and P. activus H22/12 were wrongly classified.
