溶糖消化球菌ATCC 14963 T DNA的鸟嘌呤+胞嘧啶（G+C）含量（T =模式菌株）、吲哚消化球菌ATCC 29427 T、普氏消化球菌ATCC 9321 T和大型消化球菌ATCC 15794 T的DNA的G+C含量范围为29-34摩尔%，而黑消化球菌ATCC 27731 T，消化球菌属的模式种，为51mol%。厌氧消化链霉菌ATCC 27337 T（消化链霉菌属的模式种）的DNA的G+C含量为33mol%。解淀粉消化球菌、吲哚消化球菌、普氏消化球菌和大消化球菌的DNA碱基组成类似于消化链球菌属模式种的DNA碱基组成，而不是消化球菌属模式种的DNA碱基组成。消化球菌属不希望包括G+C含量与该属的模式种的G +C含量相差甚远的任何种。厌氧消化链霉菌ATCC 27337 T与4种消化球菌属的DNA-DNA同源性比较。低G+C DNA含量范围为23- 36%。解淀粉消化球菌、吲哚消化球菌、普氏消化球菌和大消化球菌的细胞脂肪酸谱也类似于消化链球菌模式种的细胞脂肪酸谱。这些物种的其他生化特征显示其与厌氧消化链霉菌的相似性。由于这些原因，建议将4种消化球菌属转移到G+C含量较低的菌株作为Peptostreenasterolyticus（Distaso 1912）comb. nov.，吲哚消化链霉菌（Christiansen 1934）comb. nov.，普氏消化链霉菌（Foubert and道格拉斯1948）comb. nov.和大消化链霉菌（Peptostreenium magnus）（Pretenium 1933）Smith 1957 comb. rev.一组以前被称为贾夫基氏厌氧菌（Choukevitch）Pretenium的生物是一种基于表型和基因型特征可识别的消化链霉菌属。建议将这组生物命名为Peptostrepteniumtetradius sp. nov.。菌株GIFU 7672（= ATCC 35098）被指定为模式菌株。用常规方法鉴定的非糖解消化链球菌临床菌株可分为2个同源群和1个未分类群（A-1）。普氏消化链霉菌的模式菌株和作为普氏消化链霉菌接收的临床菌株之间的DNA-DNA同源性范围为0- 73%。
The guanine-plus-cytosine (G+C) contents of the DNA of Peptococcus assaccharolyticus ATCC 14963T (T = type strain), Peptococcus indolicus ATCC 29427T, Peptococcus prevotii ATCC 9321T and Peptococcus magnus ATCC 15794T ranged from 29-34 mol%, whereas the G+C content of the DNA of Peptococcus niger ATCC 27731T, the type species of the genus Peptococcus, is 51 mol%. The G+C content of the DNA of Peptostreptococcus anaerobius ATCC 27337T, the type species of the genus Peptostreptococcus, was 33 mol%. The DNA base compositions of Peptococcus asaccharolyticus, Peptococcus indolicus, Peptococcus prevotii and Peptococcus magnus resemble the DNA base composition of the type species of the genus Peptostreptococcus rather than the DNA base composition of the type species of the genus Peptococcus. It is not desirable for the genus Peptococcus to include any species whose G+C content is far from the G+C content of the type species of the genus. The levels of DNA-DNA homology between Peptostreptococcus anaerobius ATCC 27337T and the 4 Peptococcus spp. with low G+C DNA contents ranged from 23-36%. The cellular fatty acid profiles of Peptococcus asaccharolyticus, Peptococcus indolicus, Peptococcus prevotii and Peptococcus magnus also resembled the cellular fatty acid profile of the type species of Peptostreptococcus. Other biochemical characteristics of these species revealed their close resemblance to Peptostreptococcus anaerobius. For these reasons it is proposed to transfer the 4 Peptococcus spp. that have low G+C contents to the genus Peptostreptococcus as Peptostreptococcus asaccharolyticus (Distaso 1912) comb. nov., Peptostreptococcus indolicus (Christiansen 1934) comb. nov., Peptostreptococcus prevotii (Foubert and Douglas 1948) comb. nov. and Peptostreptococcus magnus (Prevot 1933) Smith 1957 comb. rev. A group of organisms previously referred to as Giaffkya anaerobia (Choukevitch) Prevot is an identifiable Peptostreptococcus sp. based on phenotypic and genotypic characteristics. The name of Peptostreptococcus tetradius sp. nov. is proposed for this group of organisms. Strain GIFU 7672 (= ATCC 35098) is designated the type strain. Clinical strains of Peptostreptococcus asaccharolyticus that were identified by conventional methods were divided into 2 homology groups and 1 unclassified group (A-1). DNA-DNA homology between the type strain of Peptostreptococcus prevotii and clinical strains received as Peptostreptococcus prevotii ranged from 0-73%.
