Starch-you use an enzyme e.g. amylase to convert the starch to sugar ,add an enzyme which breaks the starch or cellulose into sugars. The yeast will then ferment the sugars. Not sure about cellulose...

How are yeast cells in alternative fuel?
yeast can be used to ferment starch, the result alcohol can be used as fuel

Starches. All potable alcohol and most fermentation industrial alcohol is currently made principally from grains. Fermentation of starch from grain is somewhat more complex than fermentation of sugars because starch must first be converted to sugar and then to ethanol. Starch is converted enzymatically to glucose either by diastase presents in sprouting grain or by fungal amylase. The resulting dextrose is fermented to ethanol with the aid of yeast producing CO2 as co-product. A second co-product of unfermented starch, fiber, protein and ash known as distillers grain (a high protein cattle feed) is also produced.Cellulosic Materials. Each step in the process of the conversion of cellulose to ethanol proceeded with 100% yield; almost two-thirds of the mass would disappear during the sequence, most of it as carbon dioxide in the fermentation of glucose to ethanol. This amount of carbon dioxide leads to a disposal problem rather than to a raw material credit. Another problem is that the aqueous acid used to hydrolyze the cellulose in wood to glucose and other simple sugars destroys much of the sugars in the process.One way of making cellulose wastes more susceptible to hydrolysis is by subjecting them to a short burst of high energy electron beam radiation. An alternative to acid hydrolysis is the use of enzymes. Although they avoid the corrosion problems and loss of fuel product associated with acid hydrolysis, enzymes have their own drawbacks. Enzymatic hydrolysis slows as the glucose product accumulates in a reaction vessel. This end-product inhibition eventually halts the hydrolysis unless some way is found to draw off the glucose as it is formed.Last Updated: 06/06/2012
When supplied with Glucose Sucrose and starch yeast will produce the most CO2 in the presence of?
Proper temperature .
Is yeast pathogen?
Pathogenic yeast is yeast that has spread throughout the body and is causing various symptoms. It should be treated and addressed so the symptoms don't get worse.
If iodine were not available how would you determine whether starch hydrolysis had occurred?
If iodine is not available, determine whether starch hydrolysis has occurred using a refractometer or plot the yeast that forms.
How is starch and cellulose treated to allow them to be used by yeast?
The yeast has to be abled to fit into the active zone of the enzyme!
How starch and cellulose are treated to alow them to be used by yeast?
bob
How is wood treated differently to starch to make it suitable for yeast?
basically, wood and cellulose wank
Is corn starch the same as starch?
No jut like cooking yeast and brewers yeast are different.
How is cellulose changed so it can be used by yeast?
yep
Is potato starch the same as corn starch?
Tapioca starch has similar properties to corn starch. The amylose content of tapioca starch is about the same as corn starch but there are some phosphate groups present in tapioca which I think affect the solubility of starches in water.
Can yeast eat paper?
Most likely not. Yeast is only attracted to its favorite foods sugar and starch.
How are yeast cells in alternative fuel?
yeast can be used to ferment starch, the result alcohol can be used as fuel
What ingredient in making yeast bread are altered by the microbial processing?
The yeast eats the starch from the flour and produces a gas.
Will a yeast infection leave after your period?
No. The yeast infection can remain for years if you don't get it treated.
What do yeast feed on?
yeast is the thing that makes bread fluffy
Why must barley be malted before it can be used by the yeast?
to change the starch to maltose
