海洋假单胞菌与聚苯乙烯的附着取决于培养物浓度、附着时间、培养物的生长期和温度。贴壁细胞的数量随着培养物浓度和贴壁时间的增加而增加，直到贴壁表面接近饱和。贴壁细胞的数量和贴壁率在对数期培养物中最大，在稳定期和死亡期培养物中逐渐减少。温度为 3°C。 C.+-.与 20°C 下的细胞相比，1°C 下附着的稳定期细胞的比例明显降低。 C.+-. 1. 这些结果可以通过基于物理化学吸附的模型来描述，这表明非生物过程可能在细菌粘附的初始事件中发挥重要作用。
The attachment of a marine pseudomonad to polystyrene was dependent upon culture concentration, the time allowed for attachment, the growth phase of the culture and temperature. The number of attached cells increased with culture concentration and the time allowed for attachment, until the attachment surface approached saturation. The number of cells which attached and the rate of attachment was greatest with log-phase cultures and progressively decreased with stationary and death-phase cultures. A temperature of 3.degree. C .+-. 1 noticeably decreased the proportion of stationary phase cells which attached, compared with cells at 20.degree. C .+-. 1. These results can be described by a model based on physicochemical adsorption, which suggests that non-biological processes may play a major role in the initial events of bacterial adhesion.
