摘要: Abstract Although Saccharomyces cerevisiae and Debaryomyces hansenii are important for food fermentation, they considered as spoilage yeasts in various processed foods. In this study, we investigated the quantity-dependent effects of milk, egg yolk, orange juice on survival rates food-spoilage when desiccated a stainless steel surface. The protective yeast cells before after drying against disinfectants UV-C irradiation were also investigated. Microbial suspensions (0.1 mL) placed dish (50 mmφ). After 2 h at room temperature absence residue, viable cell counts S. cerevisiae D. hansenii decreased from 6 to
