返回实验室之后，他们在营养基中使这种细菌生长。

Back at the lab, they grew the bacteria in a broth of nutrients.

每次他们的试验结果都一样：处于营养贫乏培养基种的细菌菌落越是靠近生长于富营养基中生长的细菌，那么前者越粘稠。

Each time they found the same effect: the closer a nutrient-deprived colony grew to bacteria in a nutrient-rich medium, the slimier the former got.

通常这些细胞被放在富含营养的培养基上并在冷冻前进行复制。

Normally these cells would be placed in nutrient-rich cultures and be replicated before freezing.
