What is yeast: However

However, some yeast -like fungal parasites, such as Candida albicans, could cause oral and genital infections in humans 2. Yeast is one of the earliest domesticated organisms. Saccharomyces cerevisiae is the most commercially significant species that has been used by humans to produce bread, wine and beer for hundreds if not thousands of years 3. Yeast , any of about 1,500 species of single-celled fungi, several of which are of economic importance or are pathogenic. Yeasts are found worldwide in soils and on plant surfaces and are especially abundant in sugary mediums, such as flower nectar and fruits. Fresh yeast , dried yeast , and instant yeast work basically the same way, as long as you use the right amount. The difference is mainly in the preparation of the dough or batter. What specific characteristics of yeast make it a “model organism” for study and the focus of so much research? Yeast are single-celled (unicellular) organisms, making them simple to study, but possess a cellular organization similar to that found in higher, multi-cellular organisms such as humans – that is, they possess a nucleus and are therefore eukaryotes, as described above. Most importantly, the similarity in cellular organization between yeast and higher eukaryotes translates to ...
