Saccharomyces cerevisiae Cultivation

Yeast is the earliest microorganism that was domesticated and utilized by humans. The Caucasians learned to use yeast to brew alcoholic beverages in 8000 BC; in 1845, Louis Pasteur discovered and isolated pure yeast;christian Hansen, a contemporary of Pasteur, began to study yeast in depth in order to brew high-quality beer, and pure cultured and classified yeast study research.

Saccharomyces cerevisiae is the earliest microorganism to achieve industrial-scale manufacturing, and it is also the most widely used strain among yeast species. Its industrial application process also reflects the development of the biological industry. Saccharomyces cerevisiae, also known as baker's yeast or budding yeast. Saccharomyces cerevisiae is the most widely related yeast to humans, not only because it is traditionally used to make food such as bread and steamed bread and wine, but also used as a eukaryotic model organism in modern molecular and cellular biology, and its role is equivalent to model organism Escherichia coli. Saccharomyces cerevisiae is the most commonly used biological species in fermentation. Saccharomyces cerevisiae cells are spherical or oval, 5–10μm in diameter. The method of reproduction is budding.

Yeast cells have two life forms, haploid and diploid. Haploids have a simpler life cycle and reproduce by mitosis. It usually dies in times of high environmental stress. Diploid cells (the predominant form of yeast) also reproduce by simple mitosis, but can enter meiosis when external conditions are poor, producing a series of haploid spores. Haploids can mate and re-form diploids.

All strains of S. cerevisiae can be grown under aerobic conditions using glucose, maltose and trehalose. Galactose and fructose have been shown to be the two fermenting sugars that work best when Saccharomyces cerevisiae can be cultivated. The ability of yeast to use different sugars depends on whether they grow aerobically or anaerobic. Some strains cannot grow anaerobic on sucrose and trehalose.

All strains can use ammonia and urea as nitrogen sources for the medium, but cannot use nitrate because they lack the ability to reduce it to ammonium ions. In addition, S. cerevisiae can also use most amino acids, small peptides and nitrogen bases as nitrogen sources. However, histidine, glycine, cystine and lysine are not available. Saccharomyces cerevisiae does not secrete proteases, so extracellular proteins cannot be metabolized.

Saccharomyces cerevisiae cultures also require phosphorus and sulfur assimilation. Good growth of yeast also requires some metals, such as magnesium, iron, calcium and zinc.
