R Dataset / Package Stat2Data / Ethanol
On this R-data statistics page, you will find information about the Ethanol data set which pertains to Ethanol. The Ethanol data set is found in the Stat2Data R package. You can load the Ethanol data set in R by issuing the following command at the console data("Ethanol"). This will load the data into a variable called Ethanol. If R says the Ethanol data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data with the library() command. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the Ethanol R data set. The size of this file is about 293 bytes.
Ethanol
Description
Ethanol
Format
A dataset with 16 observations on the following 3 variables.
Sugar | Type of sugar: Galactose or Glucose |
O2Conc | Oxygen concentration |
Ethanol | Ethanol concentration |
Details
Many biochemical reactions are slowed or prevented by the presence of oxygen. For example, there are two simple forms of fermentation, one which converts each molecule of sugar to two molecules of lactic acid, and a second which converts each molecule of sugar to one each of lactic acid, ethanol, and carbon dioxide. This experiment was designed to compare the inhibiting effect of oxygen on the metabolism of two different sugars, glucose and galactose, by Streptococcus bacteria. In this case there were four levels of oxygen that were applied to the two kinds of sugar.
