But unlike biodiesels based on soya or other plants, it does not divert crops or land from food production into fuel production.
如今是有很多种方法来制造生物燃料，但多数情况下还是采用化学反应，发酵和热能来分解植物中的淀粉、糖分以及其他分子。
There are various ways of making biofuels, but they generally use chemical reactions, fermentation, and heat to break down the starches, sugars, and other molecules in plants.

Biofuel from food plants like corn is simply a bad idea - it does little to reduce carbon emissions, and drives up grain prices.
在此目的的驱动下，美国与欧洲对生物燃料进行了利用，这是一种可从植物中提炼的液体并能够用作为汽车与其它机动车辆的能量供应。
As part of that drive, both America and Europe have embraced biofuels-liquids derived from plants that can be used to power cars and other vehicles.
目前，大多数生物燃料或是通常由甘蔗或玉米制成的乙醇，或是由植物油制成的生物柴油。
At the moment, most biofuels are either ethanol, usually made from sugarcane or maize, or biodiesel, made from plant oils.
不过，考虑到植物在生长过程中是会吸收二氧化碳的，因而用于制造生物燃料的植物可以抵消一部分由它们作为汽车燃料而释放的二氧化碳。
But since plants absorb carbon dioxide as they grow, crops grown for biofuels should suck up about as much carbon dioxide as comes out of the tailpipes of cars that burn these fuels.
它也许是把池塘里面的藻类变成燃油，以及把植物肥料变成燃料的的关键，而不是像现在一样把有价值的食物变成生物燃料。
It might be the key to boosting oil yields from algae grown in ponds and to turning plant wastes into fuel, rather than converting valuable food into biofuel, as happens now.
生物燃料产生者利用蛋白质把植物细胞内的碳水化合物分解成一种可以被酶菌食用的粘稠状单糖混合物。
Biofuel producers use the proteins to break down the complex carbohydrates in plant cells into a soup - like mixture of simple sugars that yeast can eat.
来自纤维素质的先进生物燃料-植物废物和木头-更好，因为他们不直接同食物竞争，但他们仍然需要适度肥沃的土地来生长。
Advanced biofuels from cellulosic material - plant waste and wood - are better, because they don't compete directly with food, but they still need reasonably fertile land in which to grow.
生产生物柴油时，植物油中的脂肪需要与一种酒精作用——通常为甲醇——生成生物燃料分子。
To make biodiesel fats in the vegetable oil are reacted with a form of alcohol-usually methanol-to form the biodiesel molecule.
生产生物柴油时，植物油中的脂肪需要与一种酒精作用——通常为甲醇——生成生物燃料分子。
To make biodiesel, fats in the vegetable oil are reacted with a form of alcohol-usually methanol-to form the biodiesel molecule.
