Lab 11 & 12: Fuel from newspaper?

In this lab we'll explore the possibility of converting cellulose, for example, newspaper, tissue paper, and - obviously - dried switchgrass. into ethanol. Ethanol can be used as fuel.

Right now, the US EPA requires that gasoline in some parts of the country contain 10% ethanol. Can we get some of this ethanol from newspaper and other waste paper?

Here is an article (
2011) on enzymatic breakdown of cellulose and the production of ethanol. Here are the prompts I gave you in class.

Note also further information by Nam Sun Wang at the following page: http://www.eng.umd.edu/~nsw/ench485/lab4.htm . This page has protocols for both acid and enzyme degradation of cellulose. It's for background reading only.

We'll assess the production of glucose by two methods - thin-layer chromatography, and fermentation by yeast.
