Nope, yeast is yeast and not several types of bacteria. Yeast is our friend in bread and beer but not in our girlfriends. Bacteria is a whole different ballgame!screwdriver said:I think yeast is several types of bacteria. That bacteria can be used to breakdown the organic nutrients we add to our soil or teas.
What are yeasts? Yeasts belong to the phylum Thalophytes. Members of this phylum form the most basic division of organisms in the plant kingdom, and are an undifferentiated group. Yeasts belong to this phylum along with other funghi, algae, and bacteria. Since funghi lack chlorophyll, they are dependent for food upon other organism's production of organic food matter. (Pyler) Thus, yeast must be fed to accomplish the task of leavening the dough. Yeast used in bread baking belongs to the genus Saccharomycetes and the species cerevisiae. More about this below.
hxxp://www.theartisan.net/The_Artisan_Yeast_Treatise_Section_One.htmYeast are a tiny form of fungi or plant-like microorganism (visible only under a microscope) that exist in or on all living matter i.e. water, soil, plants, air, etc. A common example of a yeast is the bloom we can observe on grapes. As a living organism yeast needs sugars, water and warmth to stay alive. In addition, albumen or nitrogenous material are also necessary for yeast to thrive.
There are hundreds of different species of yeast identified in nature, but the genus and species most commonly used for baking is Saccharomyces cereviae. The scientific name Saccharomyces cerevisiae, means 'a mold which ferments the sugar in cereal (saccharo-mucus cerevisiae) to produce alcohol and carbon dioxide'. Yeast needs energy to survive, and has a number of ways to attain that energy. Fermentation and respiration are two ways The ultimate reaction of importance in this process is the an-aerobic conversion of simple sugars to ethyl alcohol and carbon dioxide during alcoholic fermentation as shown below. Although not shown in the fermentation reaction, numerous other end products are formed during the course of fermentation
what would the bubble do and what kind of maching? like the childs toyKAMSAI said:yeast and water with sugar and a air-bubble machine make decent co2
