彩虹色是由产生颜色的结构产生的。细菌菌落的彩虹色最近已被描述和说明。闪光般的彩虹色类，特别是为Cellulophaga lytica的一些菌株创造的，在直接照明下表现出强烈的彩虹色。这种颜色外观效应以前与拟杆菌门的其他细菌有关，但没有明确的说明和说明。为此，我们比较了各种细菌菌株的虹彩特性。研究了来自海洋和陆地环境的所有Cellulophaga物种和其他拟杆菌属菌株。一些细菌，大多数是海洋细菌，被发现是彩虹色的。虽然一个共同的反射波长的模式被记录的物种调查，光学光谱和物理测量揭示了一系列不同的闪光般的虹彩强度和颜色配置文件。重要的是，滑翔运动被发现是所有虹彩殖民地的共同特征。对C.溶藻菌落显示彩虹色与层重叠相关。滑动运动和未知的细胞间通讯过程，可能需要建立，在时间和空间上，必要的周期性结构负责虹彩外观的拟杆菌。
Iridescence results from structures that generate color. Iridescence of bacterial colonies has recently been described and illustrated. The glitter-like iridescence class, created especially for a few strains of Cellulophaga lytica, exhibits an intense iridescence under direct illumination. Such color appearance effects were previously associated with other bacteria from the Bacteroidetes phylum, but without clear elucidation and illustration. To this end, we compared various bacterial strains to which the iridescent trait was attributed. All Cellulophaga species and additional Bacteroidetes strains from marine and terrestrial environments were investigated. A selection of bacteria, mostly marine in origin, were found to be iridescent. Although a common pattern of reflected wavelengths was recorded for the species investigated, optical spectroscopy and physical measurements revealed a range of different glitter-like iridescence intensity and color profiles. Importantly, gliding motility was found to be a common feature of all iridescent colonies. Dynamic analyses of “glitter” formation at the edges of C. lytica colonies showed that iridescence was correlated with layer superposition. Both gliding motility, and unknown cell-to-cell communication processes, may be required for the establishment, in time and space, of the necessary periodic structures responsible for the iridescent appearance of Bacteroidetes.
