(单词翻译)
Scientists are tackling that dilemma… Some are developing strains that produce cellulose and sugars, and could produce the same amount of energy as corn using a fraction of the production energy and land area. Others are splicing1 genes2 from other organisms into cyanobacteria to increase the amount of carbon dioxide fixing enzymes3 present in the cells. They have created strains that produce isobutyraldehyde gas that can be easily collected and converted into isobutanol. Using bacteria to produce fuel is not only economical, it has two advantages. First, it recycles carbon dioxide which reduces greenhouse gas emissions4. Secondly5, it uses solar energy to convert carbon dioxide into liquid fuel. It is a win win situation. In the future, there may be no need to worry about petroleum6 dependency or oil spills. Drivers will pull up to the pump and fill up on Cyanogas, the green alternative.
