Ale yeast is the species Saccharomyces cerevisiae.
As a general rule, apply compressed baker's yeast species Saccharomyces cerevisiae.
Many of these are not strains of brewer's yeast(Saccharomyces cerevisiae) and may have significant differences in aroma and sourness.
Yeast(Saccharomyces cerevisiae) acts as a growth and flavoring agent, either alone
or in association with other microorganisms such as lactic bacteria.
Horizontal transfer of genes from bacteria to eukaryotes such as the yeast Saccharomyces cerevisiae
and the adzuki bean weevil Callosobruchus chinensis has occurred.
Horizontal transfer of genes from bacteria to eukaryotes such as the yeast Saccharomyces cerevisiae and the adzuki
bean beetle Callosobruchus chinensis may also have occurred.
Saccharomyces cerevisiae, the type of yeast used for making bread and beer,
is just one representative of more than 1,500 yeast species found around the world.
We do know that strains like Bifidobacterium, Lactobacillus, and Saccharomyces have been shown to improve gut health
and most supplements contain one or all of these(8).
Also called Bulgarian yogurt, it is a fermented milk product of the combination of probiotic bacteria(Lactobacillus acidophilus)
and yeast(Saccharomyces kefir) in a matrix of proteins, lipids and sugars.
In all of the known cases, some type of yeast(in this man's case Saccharomyces cerecisiae, or brewer's yeast)
ferments the sugars coming from carbohydrates or any sugary foods into ethanol(ethyl alcohol).
By fermentation the yeast species Saccharomyces cerevisiae converts carbohydrates to carbon dioxide and alcohols-
for thousands of years the carbon dioxide has been used in baking and the alcohol in alcoholic beverages.
Lager yeast is a cool bottom-fermenting yeast(Saccharomyces pastorianus)
and typically undergoes primary fermentation at 7-12 °C(45-54 °F)(the fermentation phase), and then is given a long secondary fermentation at 0-4 °C(32-39 °F) the lagering phase.
