Tissierella Collins and Shah 1986
General information
Description and emendation
Obligately anaerobic, gram-negative, non-sporeforming rods. Weakly or non fermentative. Major metabolic end products in peptone-yeast extract-glucose broth are acetic, butyric, and isovaleric acids together with low levels of other acids. 6-Phosphogluconate dehydrogenase is produced. Glucose-6-phosphate dehydrogenase, glutamate dehydrogenase, and malate dehydrogenase are absent. meso-Diaminopimelic acid is present in the cell wall peptidoglycan. Nonhydroxylated and 3-hydroxylated long-chain fatty acids are present. The fatty acids are primarily of the straight-chain saturated and iso-methyl branched-chain types. Menaquinones are absent. The DNA base composition of the type species is 28 mol% G+C.
1: Gram negative or gram positive: meso-Diaminopimelic acid or D-ornithine is present in the cell wall peptidoglycan. The cellular fatty acids are primarily straight-chain saturated and iso-methyl branched-chain or unsaturated fatty acids. Strains preferentially growing on creatinine typically produce acetate, sarcosine, N-carbamoylsarcosine, ammonia, and CO2. The G+C content of the DNA is 28 to 32 mol%.
2: Cells are all Gram-positive and D-ornithine and meso-diaminopimelic acid are present in the peptidoglycan. Some species possess malate dehydrogenase and glutamate dehydrogenase activity.
3: Terminal oval spores could be formed by some species. Genomic sizes range from 2.41 to 5.75 Mb with 4 rrn copies (except for T. creatinophila that possess 2 rrn copies).
