Crassaminicella sp. 143-21, a putative new species isolated from deep-sea hydrothermal vent chimney on the Central Indian Ridge (CIR), is an anaerobic, thermophilic and rod-shaped bacterium belonging to the family Clostridiaceae. In this study, we present the complete genome sequence of strain 143-21, comprising 2,756,133 bp with a G + C content of 31.1%. In total, 2427 protein coding genes, 121 tRNA genes and 33 rRNA genes were obtained. Genomic analysis of strain 143-21 revealed that numerous genes related to organic matter transport and catabolism, including peptide transport, amino acid transport, saccharide transport, ethanolamine transport and corresponding metabolic pathways. Further, the genome contains a large proportion of genes involved in translation, ribosomal structure, and signal transduction. These genes might facilitate microbial survival in deep-sea hydrothermal vent environment. The genome of strain 143-21 will be helpful for further understanding its adaptive strategies in the deep-sea hydrothermal vent environment.
深海热液喷口烟囱中分离出的假定新种 Crassaminicella sp. 143-21 是一株厌氧、嗜热、杆状菌，属于梭菌科。本研究介绍了菌株 143-21 的全基因组序列，其基因组大小为 2,756,133bp，G+C 含量为 31.1%。共获得 2427 个蛋白编码基因、121 个 tRNA 基因和 33 个 rRNA 基因。对菌株 143-21 的基因组分析表明，存在大量与有机物运输和代谢相关的基因，包括肽运输、氨基酸运输、糖运输、乙醇胺运输及相应的代谢途径。此外，基因组中还包含大量与翻译、核糖体结构和信号转导相关的基因。这些基因可能有助于微生物在深海热液喷口环境中的生存。菌株 143-21 的基因组将有助于进一步了解其在深海热液喷口环境中的适应策略。
