黄杆菌IR1是一种滑翔细菌，具有高度的殖民地组织，作为二维光子晶体，在光照下产生生动的结构颜色。阴沟肠杆菌B12是一种不相关的细菌，从与IR1相同位置的褐藻墨角藻中分离得到。IR1被发现是B12的捕食者。B12的包围、浸润、削弱和杀死过程支持IR1的生长。运动性和毛细性的结合促进了IR1对B12菌落的吞噬。捕食与光照无关。与野生型相比，形成光子晶体效率较低的IR1突变体在捕食时减少。相反，光子晶体的形成不利于抵抗红球菌PIR4的捕食。这些观察结果表明，创造结构颜色所需的组织具有生物功能（促进捕食），但与群体的光子特性没有直接关系。这项工作是第一个实验证据，支持黄杆菌中这种广泛存在的细胞组织类型的作用。
Flavobacterium IR1 is a gliding bacterium with a high degree of colonial organization as a 2D photonic crystal, resulting in vivid structural coloration when illuminated. Enterobacter cloacae B12, an unrelated bacterium, was isolated from the brown macroalga Fucus vesiculosus from the same location as IR1. IR1 was found to be a predator of B12. A process of surrounding, infiltration, undercutting and killing of B12 supported improved growth of IR1. A combination of motility and capillarity facilitated the engulfment of B12 colonies by IR1. Predation was independent of illumination. Mutants of IR1 that formed photonic crystals less effectively than the wild type were reduced in predation. Conversely, formation of a photonic crystal was not advantageous in resisting predation by Rhodococcus spp. PIR4. These observations suggest that the organization required to create structural colour has a biological function (facilitating predation) but one that is not directly related to the photonic properties of the colony. This work is the first experimental evidence supporting a role for this widespread type of cell organization in the Flavobacteriia.
