Remarks: |
The 16S ribosomal DNA sequences of representative members of the family Peptococcaceae were determined. The members of the family examined were divided into the following four phylogenetic groups: Peptococcus niger ATCC 27731T (T = type strain), the Sarcina-Peptostreptococcus anaerobius group, the ruminococcus-coprococcus group, and the peptostreptococcus group. Peptococcus niger, the type species of the family, was not related to other members of the family. Peptostreptococcus anaerobius ATCC 27337T, the type strain of the type species of the genus Peptostreptococcus, was closely related to Clostridium sordellii NCIB 10717T (level of sequence similarity, 85%). Sarcina ventriculi GIFU 7886, a spore-forming anaerobic gram-positive coccus, clustered with Clostridium perfringens ATCC 13124T at a similarity value of 91%. Members of the Sarcina-Peptostreptococcus anaerobius group clustered with clostridia at similarity values ranging from 85 to 91%. The type strains of Peptostreptococcus prevotii, Peptostreptococcus asaccharolyticus, Peptostreptococcus micros, and Peptostreptococcus magnus clustered at levels of sequence homology of 84 to 93%. This cluster was not included in the Peptococcus niger group or the Peptostreptococcus anaerobius group. Thus, these members of the genus Peptostreptococcus should be separated from the other members of the genus and also from members of the family Peptococcaceae. The sequence of Peptostreptococcus productus ATCC 27340T was different from the sequences of Peptostreptococcus anaerobius and Peptococcus niger. The sequence of Streptococcus hansenii ATCC 27752T, a strictly anaerobic strain, was different from the sequences of other streptococci; this strain clustered with Peptostreptococcus productus, coprococci, and ruminococci. Several phenotypic characteristics of Streptococcus hansenii ATCC 27752T were similar to characteristics of ruminococci.(ABSTRACT TRUNCATED AT 250 WORDS) |

Remarks: |
In previous studies, gram-positive bacteria which grew rapidly with peptides or an amino acid as the sole energy source were isolated from bovine rumina. Three isolates, strains C, FT (T = type strain), and SR, were considered to be ecologically important since they produced up to 20-fold more ammonia than other ammonia-producing ruminal bacteria. On the basis of phenotypic criteria, the taxonomic position of these new isolates was uncertain. In this study, the 16S rRNA sequences of these isolates and related bacteria were determined to establish the phylogenetic positions of the organisms. The sequences of strains C, FT, and SR and reference strains of Peptostreptococcus anaerobius, Clostridium sticklandii, Clostridium coccoides, Clostridium aminovalericum, Acetomaculum ruminis, Clostridium leptum, Clostridium lituseburense, Clostridium acidiurici, and Clostridium barkeri were determined by using a modified Sanger dideoxy chain termination method. Strain C, a large coccus purported to belong to the genus Peptostreptococcus, was closely related to P. anaerobius, with a level of sequence similarity of 99.6%. Strain SR, a heat-resistant, short, rod-shaped organism, was closely related to C. sticklandii, with a level of sequence similarity of 99.9%. However, strain FT, a heat-resistant, pleomorphic, rod-shaped organism, was only distantly related to some clostridial species and P. anaerobius. On the basis of the sequence data, it was clear that strain FT warranted designation as a separate species. The closest known relative of strain FT was C. coccoides (level of similarity, only 90.6%). Additional strains that are phenotypically similar to strain FT were isolated in this study.(ABSTRACT TRUNCATED AT 250 WORDS) |
