An obligately anaerobic, Gram-stain-negative, rod-shaped bacterium, designated strain 2CBH44^T, was isolated from the fecal sample of a healthy Japanese man. This strain was initially assigned as a novel species of the genus Coprobacter based on the 16S rRNA gene sequence similarities compared with other Coprobacter species. The 16S rRNA gene sequence analysis revealed strain 2CBH44^T had relatively low 16S rRNA gene sequence similarity (97.5%) to Coprobacter secundus 177^T. However, strain 2CBH44^T showed 96.9% average nucleotide identity value with C. secundus 177^T, indicating that strain 2CBH44^T and C. secundus 177^T belong to the same species. On the other hand, the digital DNA-DNA hybridization value between strain 2CBH44^T and C. secundus 177^T was 73.5%, indicating that strain 2CBH44^T is a subspecies of C. secundus. Another anaerobic, Gram-stain-variable, rod-shaped bacterium, designated strain 12CBH8^T, was also isolated from human feces. Strain 12CBH8^T had significantly low 16S rRNA gene sequence similarities (<92.0%) to the validated bacterial species within the family Oscillospiraceae. The percentage of conserved protein values between the genome of strain 12CBH8^T and that of the validated related taxa were <50%, suggesting that strain 12CBH8^T belongs to a novel genus. On the basis of the collected data, strain 2CBH44^T represents a novel subspecies of C. secundus, for which the name Coprobacter secundus subsp. similis subsp. nov. (type strain 2CBH44^T = JCM 34079^T = DSM 111570^T) is proposed. Strain 12CBH8^T represents a novel species of a novel genus, for which the name Solibaculum mannosilyticum gen. nov., sp. nov. (type strain 12CBH8^T = JCM 34081^T = DSM 111571^T) is proposed.

Coprobacter secundus 亚种。similis subsp. 十一月 和 Solibaculum mannosilyticum gen。十一月，sp。11月，从人类粪便中分离出来

从一名健康日本男性的粪便样本中分离出一种专性厌氧、革兰氏染色阴性、杆状细菌，命名为菌株 2CBH44 ^T。根据与其他Coprobacter物种相比的 16S rRNA 基因序列相似性，该菌株最初被指定为Coprobacter属的一个新物种。16S rRNA 基因序列分析显示，菌株 2CBH44 ^T与Coprobacter secundus 177 ^T具有相对较低的 16S rRNA 基因序列相似性（97.5%）。然而，菌株 2CBH44 ^T与C. secundus 177 ^T显示 96.9% 的平均核苷酸同一性值，表明菌株 2CBH44^T和C. secundus 177 ^T属于同一物种。另一方面，菌株2CBH44 ^T和C. secundus 177 ^T之间的数字DNA-DNA杂交值为73.5%，表明菌株2CBH44 ^T是C. secundus的一个亚种。另一种厌氧、革兰氏染色可变的杆状细菌，命名为菌株 12CBH8 ^T，也从人类粪便中分离出来。应变12CBH8 ^Ť有显著低16S rRNA基因序列的相似性（<92.0％），以在家庭中的验证的细菌物种Oscillospiraceae. 菌株12CBH8 ^T基因组与已验证相关分类群的保守蛋白值百分比<50%，表明菌株12CBH8 ^T属于一个新属。根据收集到的数据，菌株 2CBH44 ^T代表了C. secundus 的一个新亚种，其名称为Coprobacter secundus subsp。similis subsp. 十一月 （型菌株2CBH44 ^Ť  = JCM 34079 ^Ť  = DSM 111570 ^Ť）提出。菌株 12CBH8 ^T代表一个新属的新物种，其名称为Solibaculum mannosilyticum gen。十一月，sp。十一月 （型菌株 12CBH8^{建议 T}  = JCM 34081 ^T  = DSM 111571 ^T )。
