Yeast adhesion to and biofilm formation on surfaces is present in many different environments. In food industry, biofilms may be a source of contaminations, causing food spoilage and reducing quality of products. and are two common yeast genera involved in the spoilage of some food products. The aim of this study is to assess the potential of and species to adhere to two types of wooden surfaces (smooth and rough), one of the materials typical for the food processing industry, and investigate the influence of surface roughness of wood on the degree of yeast adhesion. The adhesion of the cells to the wooden surfaces was determined by rinsing them from the surface, followed by methylene blue staining, and quantification after imaging under microscope by automatic counting of viable cells. The results showed that all and strains were able to adhere to the wooden surfaces in a species- and strain-dependent manner. On the other hand, our data indicated that adhesion by these yeasts was not significantly affected by the roughness of the wood surfaces.
酵母在许多不同环境中都会附着于表面并形成生物膜。在食品工业中，生物膜可能是污染源，会导致食品变质并降低产品质量。[此处两个酵母属名称缺失]是涉及某些食品变质的两个常见酵母属。本研究的目的是评估[此处酵母属名称缺失]和[此处酵母属名称缺失]物种附着于两种木质表面（光滑和粗糙）的潜力，木质表面是食品加工业的典型材料之一，并研究木材表面粗糙度对酵母附着程度的影响。通过从表面冲洗细胞，然后进行亚甲基蓝染色，并在显微镜下成像后通过自动计数活细胞进行定量，来确定细胞对木质表面的附着力。结果表明，所有[此处酵母属名称缺失]和[此处酵母属名称缺失]菌株都能够以物种和菌株依赖的方式附着于木质表面。另一方面，我们的数据表明，这些酵母的附着力并未受到木材表面粗糙度的显著影响。
