SEM of yeast cells
Yeast. Coloured scanning electron micrograph (SEM) of yeast cells, Saccharomyces cerevisiae, commonly known as Bakers or Brewers yeast, growing on potato dextrose agar. Yeast is able to ferment sugar, producing alcohol & carbon dioxide in the process. It has long been used in the brewing of beer, the production of wine, and in baking of leavened bread (carbon dioxide causes the dough to rise). Medically, dried yeast is used as a source of vitamin B1, riboflavin & nicotinic acid. Yeast divide rapidly by budding off new cells (visible here). They may also reproduce sexually. Magnification: X945 at 35mm size. Coloured orange. Original is BW print B250/174. 12 -- damaged

EDITORS COMMENTS
This print showcases a coloured scanning electron micrograph (SEM) of yeast cells, specifically Saccharomyces cerevisiae, also known as Bakers or Brewers yeast. The image captures the yeast cells growing on potato dextrose agar, highlighting their intricate structures and vibrant orange hue. Yeast is renowned for its ability to ferment sugar, producing both alcohol and carbon dioxide in the process. This remarkable quality has made it an essential ingredient in brewing beer, producing wine, and leavening bread dough by causing it to rise through the release of carbon dioxide. Beyond culinary applications, dried yeast serves as a valuable source of vitamin B1, riboflavin, and nicotinic acid in medical contexts. In this SEM image, we can observe how yeast cells rapidly divide by budding off new cells—a fascinating sight that emphasizes their reproductive capabilities. The magnification level of X945 at 35mm size allows us to appreciate the intricate details of these tiny organisms. While this particular print suffered some damage during its journey through time, it still manages to captivate viewers with its scientific beauty. Overall, this photograph offers a glimpse into the microscopic world of fungi—showcasing nature's incredible diversity and reminding us of the significant role that yeasts play in various fields such as food production and medicine.
