Taxono-genomics is an innovative concept coined for the description of new bacterial species. Phenotypic characteristics were combined with a genomic approach to describe two new species within the Clostridium senso stricto genus: Clostridium culturomicium strain CL-6^T and Clostridium jeddahitimonense strain CL-2^T, both isolated from the gut microbiota of an obese man from Saudi Arabia. Strains CL-6^T and CL-2^T shared a similarity of 98.4% with the 16S rRNA gene of Clostridium subterminale strain JCM 1417^T (accession number NR113027) and 98% with that of Clostridium disporicum strain DS1^T (accession number NR026491), respectively. The highest OrthoANI values were shared with Clostridium punense for strain CL-6^T (70.8%) and with Clostridium disporicum for strain CL-2^T (87.1%). Additionally, strain CL-6^T and strain CL-2^T shared a 16S rRNA similarity of 91.4%. Both strains were anaerobic, spore-forming and Gram-stain-positive non-motile bacilli. The genome of Clostridium culturomicium strain CL-6^T is 4,325,182 bp long with 32.2% GC content. As for Clostridium jeddahitimonense strain CL-2^T, the genome is 4,074,758 bp long with 29.2% GC content.

分类基因组学是一个创新概念，用于描述新的细菌物种。将表型特征与基因组方法相结合，描述了狭义梭菌属内的两个新物种：培养梭菌CL-6 ^T和吉达希莫氏梭菌CL-2 ^T菌株，两者均从沙特阿拉伯肥胖男性的肠道微生物群中分离出来。菌株CL-6 ^Ť和CL-2 ^Ť共享98.4％的相似性与16S rRNA基因近端梭菌菌株JCM 1417 ^Ť（登录号NR113027）和98％与的梭菌disporicum菌株 DS1 ^T（登录号 NR026491），分别。最高的 OrthoANI 值与Clostridium punense菌株 CL-6 ^T (70.8%) 和Clostridium disporicum菌株 CL-2 ^T (87.1%)共享。此外，菌株 CL-6 ^T和菌株 CL-2 ^T具有 91.4% 的 16S rRNA 相似性。两种菌株都是厌氧的、形成孢子的和革兰氏染色阳性的非运动性杆菌。Clostridium culturomicium菌株 CL-6 ^T的基因组长4,325,182 bp，GC 含量为 32.2%。至于Clostridium jeddahitimonense菌株 CL-2 ^T，基因组长 4,074,758 bp，GC 含量为 29.2%。
