The bacteria secrete the alkanes, which can then by easily collected and used as a fuel.

They confirmed their discovery by incorporating the genes into e. coli and measuring the alkanes that the bacteria subsequently made.

他们通过将产烷必须的基因植入大肠杆菌并对最终产生的烷进行测量，验证了他们的发现。

Such alkanes are the main ingredients of diesel fuel.

这种烷烃是柴油的主要成分。
