Fermentation Using Yeasts

*This is a lab report from a previous 181 lab written by a student. It has been modified and cut short a little to convey some important pointers to writing lab reports. The left columns indicate the pointers and some instructions. Please read those carefully. The text material has been provided so that you may have an example of a lab that you have already done.
*You should not write the report in table format (this is only for illustration). Also, I expect graphs, tables, and math equations in the result section.
