Zygosaccharomyces bailii yeast, SEM

Coloured scanning electron micrograph (SEM) of Zygosaccharomyces bailii - yeast spoilage fungus. Zygosaccharomyces bailii formerly known as Saccharomyces bailii is a well known yeast that is involved in food and beverage spoilage. Shown here are yeast cells reproducing asexually by multilateral budding. The buds can arise from various sites on the cells. Z. bailii has caused significant economic losses to the food industry. A wide range of acidic and high sugar products such as fruit concentrates, wines, soft drinks, syrups, ketchup, mayonnaise, pickles and salad dressings are susceptible to spoilage, but they are considered to have a stable shelf life. They are however included in the list of foods that can be affected by dangerous spoilage yeasts including Z. bailii . Z. bailii possesses the most significant and diversified resistance characteristics enabling it to survive and proliferate in very extreme conditions. Magnification: x800 when
