With all bacteria tested, addition of phenylacetaldehyde leads to light emission. The latter is markedly stronger with gram-negative bacteria, presumably because they possess a thinner wall and an extra external lipophilic membrane. Consistent with this explanation, the bactericidal effect of phenylacetaldehyde is also stronger with gram-negative bacteria. The spectrum of the emitted light shows maximal emission in the 500 nm region and is very similar to that observed when a protein (bovine serum albumin), free amino acids or isopropylamine reacts with phenylacetaldehyde.
对所有测试的细菌而言，添加苯乙醛会导致发光。革兰氏阴性菌的发光明显更强，推测是因为它们的细胞壁较薄且有一层额外的外部亲脂性膜。与这一解释相符的是，苯乙醛对革兰氏阴性菌的杀菌作用也更强。发射光的光谱在500纳米区域显示出最大发射，并且与蛋白质（牛血清白蛋白）、游离氨基酸或异丙胺与苯乙醛反应时观察到的光谱非常相似。
