The creminis are the darker variety, but you could also use white button mushrooms.

creminis 是颜色较深的品种，但你也可以使用白色蘑菇。

The current they generate is thanks to cyanobacteria, a kind of aquatic bacteria, which the researchers 3D-printed onto plain old button mushroom caps, along with a conductive graphene ink.

它们产生的电流要归功于蓝藻，一种水生细菌，研究人员将其 3D 打印到普通的旧纽扣蘑菇帽上，以及导电石墨烯墨水。

So they bought some white button mushrooms from a local grocery store, the same kind you might pick up to make a tasty batch of stroganoff or sprinkle on your pizza.

所以他们从当地的杂货店买了一些白蘑菇，这种蘑菇可以用来做一批美味的奶油批萨或洒在比萨饼上。
