4·Biofilm, the researchers think, could serve a dual function: it could help bacterial colonies grow toward resources as a collective swarm, and it might also help block out competing colonies.
研究人员们认为，生物膜具有双重作用，一方面它能够是菌落朝着营养源成群生长，同时它又能够阻止竞争菌落对于资源的掠夺。

1·Staining from coffee is very superficial, effecting just the biofilm, a thin layer of bacteria which covers the teeth and gums, and doesn't penetrate through the enamel itself.
咖啡的着色是浅表性的，仅仅影响菌膜——覆盖牙齿和牙龈的一个很薄的细菌层，并不能穿透牙釉质。
