Passage Translation Directions: Translate the following passage into Chinese. LS9 has used its technology to turn microbes into factories for fatty acids containing between 8 and 20 carbon atoms —the optimal number for biodiesel. But it also plans to make what it calls “biocrude”. In this case the fatty acids would have 18〜30 carbon atoms, and the final stage of the synthetic pathway would clip off the oxygen atoms to create pure hydrocarbons. This biocrude could be fed directly into existing oil refineries, without any need to modify them.
