1.   Yeast is essential for the fermentation that produces alcohol.

2.   Alcohol can be produced from plants such as sugar cane and cassava by fermentation and distillation.

3.   In so doing it multiplies many times over and produces alcohol.

4.   It did not indicate that a body often produces alcohol after death.

5.   Other researchers had previously modified the bacterium to produce alcohol from organic waste.

6.   The bacteria that cause decomposition produce alcohol as a byproduct.

7.   The bacteria are generally present in air and water, and if the weather at the crash scene is warm enough, they will produce alcohol within hours.

8.   The ethanol key would be a little broader, fitting in a whole class of bacteria that produce alcohol.
