Stefan was curious whether or not the biochar mix may later release the phosphate it had taken up. Then that nutrient is likely to be returned to the soil as a plant fertilizer. To test the thought, the teen ready small cups of sand during which he would grow lettuce seeds. Some cups had solely sand. These served as his control. The others additionally contained his phosphate-loaded mixture. After 12 days, the teen measured how massive the lettuce seedlings had grown.

Cellulose derived from plant materials is produced by any of a variety of enzymes, depending on the form of plant materials getting used. These catalysts dine on complex carbohydrates, like sugars, and expel cellulose and carbon dioxide as waste in the process. These enzymes are costly, nonetheless, round 20 cents for every gallon of purified ethanol [source: Federal Trade Commission]. What’s extra, the fermentation technique of cellulose with yeast requires a different enzyme, Pimtaş additional raising prices. In 2006, plant geneticist Albert Kausch stated that with present cultivation and production strategies, the cost per gallon of cellulosic ethanol can be $2.70. That’s nonetheless cheaper than gas­oline, but Kausch believes it could be introduced right down to round $1 per gallon [source: Newswise]. One of many methods to realize this dramatic value discount is to develop cheaper enzymes and find a single enzyme that can both break down cellulose and ferment ethanol.
