We as humans are currently unable to digest much cellulose from plants. This is due to the fact that the cell is so dense and tightly packed that our enzymes cannot attack the beneficial cellulose. Cellulose is a great product that can be converted to ethanol. If we could create this ethanol in our bodies, it could be used for biofuel and become very useful. The biomass can be used for the fermentable sugars which can process the ethanol. Now the only process we have involves toxic chemicals and requires a large amount of energy. Scientists attempted to see what happens to the cells when pre-treated with ammonia. This experiment had worked since it weakened the cell more than usual, by loosening hydrogen bonds within the cells. With this we have found a step that can lead us in a great way towards changing some of our diets if we could perfect this system.
