Binding to surfaces by fungal spores is a prerequisite to biofilm formation. The interactions of polytetrafluoroethylene (PTFE), glass, and silicon with three fungal spores, of differing shapes and sizes ( 1957, 1988, and ), were investigated. A multifractal analysis was conducted to provide quantitative measures of density, dispersion, and clustering of spores on the surfaces. The PTFE, glass, and silicon surfaces presented a range of surface topographies and wettabilities. PTFE was the roughest and most non-wettable surface, whereas silicon was the opposite in terms of both these aspects. The species were more non-wettable than . Overall, 1957 attached in higher numbers to PTFE, whereas 1988 and bound in highest numbers to glass. The results of this work demonstrated that the overall substratum surface roughness influenced spore binding rather than the physicochemical or chemical properties of surfaces or spores.
真菌孢子与表面的结合是生物膜形成的前提条件。研究了聚四氟乙烯(PTFE)、玻璃和硅与三种形状和大小不同的真菌孢子(1957、1988和 )之间的相互作用。进行了多重分形分析,以提供孢子在表面上的密度、分散度和聚集的定量测量。PTFE、玻璃和硅表面呈现出一系列表面形貌和润湿性。PTFE是最粗糙且最不亲水的表面,而硅在这两个方面则相反。 物种比 更不亲水。总体而言,1957以更高的数量附着于PTFE,而1988和 以最高的数量附着于玻璃。这项工作的结果表明,总体基质表面粗糙度影响孢子结合,而不是表面或孢子的物理化学或化学性质。
