Brochothrix thermosphacta is one of the dominant bacterial species associated with spoilage of chilled meat and seafood products through the production of various metabolites responsible for off-odors. However, metabolic pathways leading to meat and seafood spoilage are not all well known. The production of spoiling molecules seems to depend both on strains and on food matrix. Several B. thermosphacta genome sequences have been reported, all issued from meat isolates. Here, we report four genome sequences, one complete and three as drafts. The four B. thermosphacta strains CD 337, TAP 175, BSAS1 3, and EBP 3070 were isolated from different ecological niches (seafood or meat products either spoiled or not and bovine slaughterhouse). These strains known as phenotypically and genetically different were selected to represent intraspecies diversity. CD 337 genome is 2,594,337 bp long, complete and circular, containing 2593 protein coding sequences and 28 RNA genes. TAP 175, BSAS1 3, and EBP 3070 genomes are arranged in 57, 83, and 71 contigs, containing 2515, 2668, and 2611 protein-coding sequences, respectively. These genomes were compared with two other B. thermosphacta complete genome sequences. The main genome content differences between strains are phages, plasmids, restriction/modification systems, and cell surface functions, suggesting a similar metabolic potential but a different niche adaptation capacity.

四种嗜热溴化拟南芥菌株的完整序列和三个基因组草图草案，CD 337，TAP 175，BSAS1 3和EBP 3070

嗜热芽孢杆菌是通过产生引起异味的各种代谢产物而与冷藏肉类和海鲜产品变质相关的主要细菌之一。然而，导致肉类和海鲜变质的代谢途径并不是众所周知的。破坏分子的产生似乎既取决于菌株又取决于食物基质。已经报道了数种嗜热芽孢杆菌的基因组序列，这些序列均来自肉分离物。在这里，我们报告了四个基因组序列，一个完整，三个为草图。从不同的生态位（海鲜或肉类产品是否变质以及是否有牛屠宰场）中分离出四种嗜热芽孢杆菌菌株CD337，TAP 175，BSAS1 3和EBP 3070。选择这些表型和遗传上不同的菌株来代表种内多样性。CD 337基因组长2,594,337 bp，完整且呈环状，包含2593个蛋白质编码序列和28个RNA基因。TAP 175，BSAS1 3和EBP 3070基因组排列在57、83和71个重叠群中，分别包含2515、2668和2611个蛋白质编码序列。将这些基因组与另外两个嗜热芽孢杆菌的完整基因组序列进行比较。菌株之间的主要基因组含量差异是噬菌体，质粒，限制/修饰系统和细胞表面功能，表明具有相似的代谢潜能，但具有不同的生态位适应能力。将这些基因组与另外两个嗜热芽孢杆菌的完整基因组序列进行比较。菌株之间的主要基因组含量差异是噬菌体，质粒，限制/修饰系统和细胞表面功能，表明具有相似的代谢潜能，但具有不同的生态位适应能力。将这些基因组与另外两个嗜热芽孢杆菌的完整基因组序列进行比较。菌株之间的主要基因组含量差异是噬菌体，质粒，限制/修饰系统和细胞表面功能，表明具有相似的代谢潜能，但具有不同的生态位适应能力。
