The adhesion of cells of Salmonella typhimurium to albite, biotite, felspar, magnetite and quartz was correlated to the presence of fimbriae and degree of hydrophobicity and charge of the bacterial surface. It was found that the presence of fimbriae resulted in a higher degree of adhesion compared to adhesion of nonfimbriated cells. The significance of the physico-chemical characteristics of fimbriae was shown by a direct linearity between high hydrophobicity of fimbriated cells and degree of adhesion to the mineral particles. Fimbriated cells exhibited higher negative as well as positive surface charge as compared to nonfimbriated cells. Adhesion to several of the minerals was shown to be independent of the extent of negative charges on the bacterial surfaces. A high degree of adhesion to biotite, possibly due to a combination of characteristics of the particles, was not related to either bacterial fimbriation or a physico-chemical characteristic of the bacterial surface. The results of the nonspecific adhesion observed are discussed in terms of available binding sites and distribution of physico-chemical characteristics on the bacterial cell surface structures.
鼠伤寒沙门氏菌细胞对白长石、黑云母、长石、磁铁矿和石英的黏附与菌毛的存在、细菌表面的疏水性程度和电荷有关。研究发现，与无菌毛细胞的黏附相比，菌毛的存在导致更高程度的黏附。菌毛细胞的高疏水性与对矿物颗粒的黏附程度之间的直接线性关系表明了菌毛物理化学特性的重要性。与无菌毛细胞相比，有菌毛细胞表现出更高的负电荷以及正电荷。对几种矿物质的黏附被证明与细菌表面负电荷的程度无关。对黑云母的高度黏附可能是由于颗粒特性的综合作用，与细菌菌毛形成或细菌表面的物理化学特性均无关。根据细菌细胞表面结构上可用的结合位点和物理化学特性的分布，讨论了观察到的非特异性黏附结果。
