The luciferin-luciferase bioluminescence method was used to estimate the number of bacteria retained in neutral and amphiphilic gels and those in the eluate to determine the hydrophobic surface properties of bacteria by using hydrophobic interaction chromatography. Good correlations were found between viable counts and ATP content for Escherichia coli, Pseudomonas fragi, and Listeria monocytogenes. ATP determination was more rapid than viable counts for characterizing the relative hydrophobicity of L. monocytogenes. Quantitative estimations of adsorption of L. monocytogenes on octyl-Sepharose indicate that this microorganism is hydrophilic.
采用荧光素-荧光素酶生物发光法,通过疏水相互作用色谱法来估算保留在中性和两亲性凝胶中的细菌数量以及洗脱液中的细菌数量,以确定细菌的疏水表面特性。对于大肠杆菌、脆弱拟杆菌和单核细胞增生李斯特菌,发现活菌计数与ATP含量之间具有良好的相关性。在表征单核细胞增生李斯特菌的相对疏水性方面,ATP测定比活菌计数更快。对单核细胞增生李斯特菌在辛基琼脂糖上的吸附进行定量估计表明,这种微生物是亲水的。
