Anaerococcus jeddahensis sp. nov., a New Bacterial Species Isolated From Healthy Nomadic Bedouin Woman From Saudi Arabia.

An understanding of the microbial diversity of the human body has generated significant interest in recent years. With the advent of MALDI-TOF mass spectrometry, high-speed sequencing, and the rebirth of microbial culture, knowledge of human microbiota is growing. Using culturomics, a strategy to explore the microbial diversity of samples, coupled with a taxono-genomic strategy, we isolated a new bacterium named Anaerococcus jeddahensis sp. nov. strain SB3T. This strain was isolated from the stool sample of a healthy nomadic Bedouin woman from Saudi Arabia. Here, we describe the characteristics of this organism, and the complete genome sequence and annotation. Strain SB3T is a Gram-positive obligate anaerobic coccus which is non-motile and non-spore forming. Fatty acid analysis shows that the major fatty acid is by far hexadecanoic acid (C16:0; 52%). Its genome is 1,903,534 bp long and has 29.70 mol% of G+C content. It contains 1756 protein-coding genes and 53 RNA genes. These results show that strategy provides a better understanding of the microorganism and that is a good methodology for microbial identification and characterization.
