北原酒球菌（Oenococcus kitaharae）是酒球菌属（Oenococcus）中第二个被鉴定的成员，也是工业上重要的葡萄酒细菌Oenococcus oeni的近亲。为了深入了解这一新物种，对O. kitaharae，DSM 17330进行测序。通过对两个种的基因组序列的比较，发现O. kitaharae DSM 17330含有许多在细胞防御中具有预测功能的基因（细菌素、抗微生物剂、限制修饰系统和CRISPR基因座），这些基因在O. oeni。这两个基因组似乎也差异编码与氨基酸生物合成和碳水化合物利用相关的几种代谢途径，并具有直接的表型后果。这表明这两个物种进化出了不同的生存技术，以适应其特定的环境生态位。O. oeni已经适应了在严酷但可预测的葡萄酒环境中生存，这种环境提供了很少的竞争物种。然而O.北原似乎已经适应了一种生长环境，在这种环境中，生物竞争通过在其整个基因组中积累生物防御分子，如细菌素和限制修饰系统，提供了显著的选择压力。
Oenococcus kitaharae is only the second member of the genus Oenococcus to be identified and is the closest relative of the industrially important wine bacterium Oenococcus oeni. To provide insight into this new species, the genome of the type strain of O. kitaharae, DSM 17330, was sequenced. Comparison of the sequenced genomes of both species show that the genome of O. kitaharae DSM 17330 contains many genes with predicted functions in cellular defence (bacteriocins, antimicrobials, restriction-modification systems and a CRISPR locus) which are lacking in O. oeni. The two genomes also appear to differentially encode several metabolic pathways associated with amino acid biosynthesis and carbohydrate utilization and which have direct phenotypic consequences. This would indicate that the two species have evolved different survival techniques to suit their particular environmental niches. O. oeni has adapted to survive in the harsh, but predictable, environment of wine that provides very few competitive species. However O. kitaharae appears to have adapted to a growth environment in which biological competition provides a significant selective pressure by accumulating biological defence molecules, such as bacteriocins and restriction-modification systems, throughout its genome.
