Baker's Yeast
Baker's yeast is a leavening agent used in baking bread. Use of this leavening agent in bread-making results in a light and tasty bread. Without yeast, bread has a heavier texture, is less tasty and often called flatbreads.

Yeast belong to Kingdom Protista. Animals have eukaryotic cells.
no carbon dioxed does
Answer:
The bubbles in beer fall into two categories:
- In naturally fermentation the bubbles are caused by carbon dioxide released by a secondary fermentation byyeast added to the beer after primaryfementation and shortly before bottling
- In industrial production the carbon dioxide captured during primary fermentation is captured and reinjected into the beer as bottled to provide the bubbles. SOme bottlers (Guiness stout_ use nitrogen to provide a smaller and creamier bubble for a firmer head.
Even though some articles state that only aged or ripened cheese contain yeast, most sources indicate that all cheese does.
Here's a good source of foods to avoid in Related Links.
Also watch out for these ingredients on labels: Vegemite, Promite, Bovril, Marmite, Cenovis, Oxo. They are derived from yeast. If you're planning to go on a totally yeast-free diet, it's best if you check with the manufacturer.
What is a substitue for yeast?
Yeast has a very specific function, so there is no substitute.
There are different forms of yeast (compressed, active dry, instant) and these can generally be substituted for each other.
3 factors which affect the growth in yeast?
temperature (30 degrees celcius is the optimum temp for yeast growth), nutrients (e.g. sucrose, fructose, glucose, lactose - (does not affect yeast growth), pH level (5 - 6 is the optimum pH level for growth)
Yeast dough is used to make all types of bread and pizza crusts. It is also used for rolls, including bagels, and snacks, including pretzels.
How long does it take to travel by train from Venice to San Mariano?
San Mariano is in the Philippines (according to Wikipedia). There is no way you can get a train there from Venice!
What flour should be used for yeast?
Can you? Yes.
Should you? No. For best results, all the ingredients for baking bread should be at room temperature unless otherwise specified in the recipe. Having ingredients too cold can cause the bread to not rise sufficiently, which will give you dense and tough bread.
Baker's yeast has the scientific name of Saccharomyces cerevisiae. This means that the genus of baker's yeast is Saccharomyces and the species is cerevisiae.
What happens to yeast when added to water?
When yeast is in cold water, it goes dormant. If the water is too cold, though, it will kill the yeast.
Does pancakes have yeast in them?
Using yeast would not give you something you can call a "pancake", but a "griddle cake" instead. You can, but you must give the yeast time to multiply (which you would not need to do with baking powder), which means making the yeasted batter and leaving it for about an hour to double in volume, before you can cook with it. Otherwise the griddle cakes will not rise.
You can make pancakes without any leavening agents; see French crepes.
What is rolled-in yeast dough?
Yeast dough is dough (basically a mixture of flour, water, salt) to which yeast (a form of fungi) has been added to cause the dough to 'rise', add in dimension by filling the dough with carbon dioxide given off by the yeast. Dough without yeast does not expand.
What is the function of fat in yeast dough?
The main purpose is to make the bread more tender, but it also adds flavor and helps it to brown when baking.
It is sometimes called "dried yeast". It is yeast that has had all of it's moisture removed (so that it can be stored indefinitely), but becomes active again as soon as it is dissolved in water. It is sort of the opposite of "fresh yeast", but it still gives good results when used in baking. (To use it in cooking, you should always use half of the amount of yeast that's recommended for when using "fresh yeast", since dried yeast is twice as concentrated.)
Describe two techniques for preparing yeast breads?
Mixing Yeast Doughs is for making bread rise as the yeast in the bread releases gas which allows the bread to rise usually in a period called resting the bread. Hope I helped ^_^
Unpressed yeast does not. However, "autolyzed yeast" or "yeast extract" is subject to processing. During the processing, protein is broken down, and glutamic acid is freed. The finished autolyzed yeast product will contain processed free glutamic acid (MSG).
Can brewers yeast cure candidiasis?
I don't have a definitive answer, but I can share a few bits from my own google searchings. This study seemed to indicate the effectiveness of a "proanthocyanidin-enriched cranberry fraction" against oral candida: http://iadr.confex.com/iadr/2008Toronto/techprogram/abstract_105102.htm This article describes how cranberry may be useful for candida because it will "inhibit 'bad' bacteria such as Candida from clinging on to the walls of your urinal tract" and "balance out the pH level in your vagina, which makes it inhospitable for yeast to live in": http://ezinearticles.com/?Candida-Help---3-Tips-For-Chronic-Yeast-Infections&id=1025336 It doesn't give reference to any research supporting though, doctors do pretty commonly prescribe cranberry juice for urinary tract infections. Here is an article that talks about some of the research done with cranberry, and seems to indicate that the research is not conclusive. http://74.125.93.132/search?q=cache:http://164.41.105.58/farmacologiaclinica/crawberryeinfeccaourinaria.pdf
Is the yeast the same yeast that give women yeast infections?
no, yeast is for bread baking or used to make dough rise. yeast infections are like jock itch except in women. easy simple way to get rid of it is an ointment prescribed by a docter or over the counter.
It was first founded by the Egyptians, archaeologists have found hieroglyphics and paintings of early bakeries, also they have found bakeries in which grinding bowls were ready to utilize yeasted bread.
I did some research on the web and thanks to Dakotayeast.com, the website for a major commercial yeast manufacturer for Baker's yeast had the information. Here it is:
Yeasts can be considered man's oldest industrial microorganism. It's likely that man used yeast before the development of a written language. Hieroglyphics suggest that that ancient Egyptians were using yeast and the process of fermentation to produce alcoholic beverages and to leaven bread over 5,000 years ago. The biochemical process of fermentation that is responsible for these actions was not understood and undoubtedly looked upon by early man as a mysterious and even magical phenomenon.
It is believed that these early fermentation systems for alcohol production and bread making were formed by natural microbial contaminants of flour, other milled grains and from fruit or other juices containing sugar. Such microbial flora would have included wild yeasts and lactic acid bacteria that are found associated with cultivated grains and fruits. Leaven, referred to in the Bible, was a soft dough-like medium. A small portion of this dough was used to start or leaven each new batch of bread dough. Over the course of time, the use of these starter cultures helped to select for improved yeasts by saving a "good" batch of wine, beer or dough for inoculating the next batch. For hundreds of years, it was traditional for bakers to obtain the yeast to leaven their bread as by-products of brewing and wine making. As a result, these early bakers have also contributed to the selection of these important industrial microorganisms.
It was not until the invention of the microscope followed by the pioneering scientific work of Louis Pasteur in the late 1860's, that yeast was identified as a living organism and the agent responsible for alcoholic fermentation and dough leavening. Shortly following these discoveries, it became possible to isolate yeast in pure culture form. With this new found knowledge that yeast was a living organism and the ability to isolate yeast strains in pure culture form, the stage was set for commercial production of baker's yeast that began around the turn of the 20th century. Since that time, bakers, scientists and yeast manufacturers have been working to find and produce pure strains of yeast that meet the exacting and specialized needs of the baking industry.

No yeast can't harm the human body because that is one of the ingredients to make bread. Look for a bread book to see for yourself.
yes although first the sucrose needs to be broken down into monosaccharides such as glucose this is done by an enzyme found in the yeast from here the zymase in the yeast can then breakdown the monosaccharides
