Abstract

Variations in surface hydrophobicity of six Lactobacillus strains with and without an S-layer upon changes in ionic strength are derived from contact angle measurements with low- and high-ionic-strength aqueous solutions. Cell surface hydrophobicity changed in response to changes in ionic strength in three out of the six strains, offering these strains a versatile mechanism to adhere to different surfaces. The dynamic behavior of the cell surface hydrophobicity could be confirmed for two selected strains by measuring the interaction force between hydrophobic and hydrophilic tips with use of atomic force microscopy.

摘要

通过对低离子强度和高离子强度水溶液进行接触角测量，得出了六株有或无S层的乳酸杆菌菌株在离子强度变化时表面疏水性的变化情况。在六株菌株中的三株中，细胞表面疏水性随离子强度的变化而改变，这为这些菌株提供了一种附着于不同表面的通用机制。通过使用原子力显微镜测量疏水和亲水尖端之间的相互作用力，可以证实两种选定菌株的细胞表面疏水性的动态行为。
