Bacterial luciferase activity was detected in light organ extracts of squids, fishes, and pyrosomes, suggesting that these systems are derived from bacteria-animal symbioses. In none of these cases was it possible to culture luminouis bacteria. Analyses of the decay kinetics show that the luciferases from the squid, ceratioid, and pyrosome light organs are all similar to bacterial luciferases from the genus Photobacterium, while those from the anomalopid light organs are different.
在鱿鱼、鱼类和磷虾的光器官提取物中检测到细菌荧光素酶活性，这表明这些系统是源自细菌-动物共生体。在这些情况下，都不可能培养发光细菌。衰减动力学分析表明，鱿鱼、鳍足类和磷虾光器官的荧光素酶都与 Photobacterium 属的细菌荧光素酶相似，而异常光器官的荧光素酶则不同。
