Yeast. Coloured scanning electron micrograph of yeast cells,Saccharomyces cerevisiae,commonly known as baker's or Brewer's 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 & in baking of leavened bread (carbon dioxide causes the dough to rise). Medically,it is used as a source of vitamin B1,riboflavin & nicotinic acid. Yeast divide rapidly by budding off new cells (visible here). They also reproduce sexually.
