They then grew model plants in the lunar soil simulant containing these three bacteria species.

随后，研究人员在这三种细菌处理后的模拟月壤中播种了实验模式植物。

Besides, levels of chlorophyll — responsible for harvesting energy from light — in the model plants were about double that of those grown without bacteria.

此外，种植 24 天后，这些植物的叶绿素含量（负责从光中吸收能量）也比没有细菌的对照模拟物中的植物增加一倍。
