Isolated from intertidal sediment of the Yellow Sea, China, Bremerella sp. P1 putatively represents a novel species within the genus Bremerella of the family Pirellulaceae in the phylum Planctomycetota. The complete genome of strain P1 comprises a single circular chromosome with a size of 6,955,728 bp and a GC content of 55.26%. The genome contains 5772 protein-coding genes, 80 tRNA and 6 rRNA genes. A total of 147 CAZymes and 128 sulfatases have been identified from the genome of strain P1, indicating that the strain has the capability to degrade a wide range of polysaccharides. Moreover, a gene cluster related to bacterial microcompartments (BMCs) formation containing genes encoding the shell proteins and related enzymes to metabolize fucose or rhamnose is also found in the genome of strain P1. The genome of strain P1 represents the second complete one in the genus Bremerella, expanding the understanding of the physiological and metabolic characteristics, interspecies diversity, and ecological functions of the genus.
从中国黄海潮间带沉积物中分离得到的 Bremerella sp. P1 可能代表了 Pirellulaceae 家族 Bremerella 属中的一个新种，该属属于浮霉菌门。菌株 P1 的全基因组由一个大小为 6955728bp、GC 含量为 55.26%的单环染色体组成。基因组包含 5772 个蛋白编码基因、80 个 tRNA 和 6 个 rRNA 基因。从菌株 P1 的基因组中总共鉴定出 147 个 CAZymes 和 128 个硫酸盐酶，表明该菌株具有降解广泛多糖的能力。此外，在菌株 P1 的基因组中还发现了一个与细菌微区室 (BMCs) 形成相关的基因簇，其中包含编码壳蛋白的基因以及代谢岩藻糖或鼠李糖的相关酶。菌株 P1 的基因组代表了 Bremerella 属中的第二个完整基因组，扩展了对该属生理和代谢特征、种间多样性和生态功能的理解。
