A large number of Gram-negative, motile, mesophilic, violacein-producing bacteria were isolated from the soils and roots of Vaccinium macrocarpon Ait. and Kalmia angustifolia L. plants and from irrigation ponds associated with wild and cultivated cranberry bogs in Massachusetts, USA. Phylogenetic analyses of 16S rRNA gene sequences placed these isolates in a clade with Chromobacterium species, but the specialized environment from which they were isolated, their low genomic DNA relatedness with Chromobacterium violaceum ATCC 12472(T) and C. subtsugae PRAA4-1(T), significant differences in fatty acid composition and colony morphology indicate that the cranberry and Kalmia isolates comprise a separate species of Chromobacterium, for which the name Chromobacterium vaccinii sp. nov. is proposed. Strain MWU205(T) ( = ATCC BAA-2314(T) = DSM 25150(T)) is proposed as the type strain for the novel species. Phenotypic analysis of 26 independent isolates of C. vaccinii sp. nov. indicates that, despite close geographical and biological proximity, there is considerable metabolic diversity among individuals within the population.
从美国马萨诸塞州的蔓越莓沼泽地的土壤、根系以及灌溉池塘中分离到大量的革兰氏阴性、运动性、嗜温、产紫罗酮的细菌。16S rRNA 基因序列的系统发育分析将这些分离物置于与 Chromobacterium 属的一个分支中，但它们的特殊生境、与 Chromobacterium violaceum ATCC 12472(T) 和 C. subtsugae PRAA4-1(T) 的低基因组 DNA 相关性、脂肪酸组成和菌落形态的显著差异表明，蔓越莓和 Kalmia 分离物构成了 Chromobacterium 的一个单独种，提议将其命名为 Chromobacterium vaccinii sp. nov.。MWU205(T) 株（ = ATCC BAA-2314(T) = DSM 25150(T)）被提议为该新种的模式株。对 26 个独立的 C. vaccinii sp. nov. 分离物的表型分析表明，尽管地理位置和生物关系密切，但在种群内个体之间存在相当大的代谢多样性。
