Can someone describe the conditions under which fermentation of sugars is promoted? And also does anyone know what the equation for the fermentation of glucose to ethanol?
Summary for 9.3. Process information from secondary sources to summarise the processes involved in the industrial production of ethanol from sugar cane.
Fermentation requires the enzymes found in yeast.
The fermentation occurs in a sealed flask, with a tube coming out leading into a sealed beaker with a cork lid witha hole in it, in that beaker has lime water. CO2 will change the colour of the lime water.
The best temperature for the reaction is 37 C.
The concentration of ethanol in solution must be 15% or below.
A small amount of yeast nutirents such as phosphate salt must be added.
