While the cost to produce corn ethanol averaged approximately 67 cents per liter ($2.54 per gallon), the cost to produce cellulosic ethanol was about 94 cents per liter ($3.55 per gallon).he reduced cost of enzymes has also be a factor contributing to the reduction in cellulosic ethanol production costs. BNEF said enzymes contributed 30 percent of the total production cost in 2008, but represented only 16 percent of the cost in 2012, a 72 percent reduction.

Avoid strong sunlight, uv lamps or tanning booths while using Differin. Use a high SPF when outside in sunny weather.
