Staph saprophyticus can also form adherent biofilms on medical implants, typically the indwelling urinary catheters.

腐生葡萄球菌还可以在医疗植入物上，通常是留置导尿管上，形成粘附的生物膜。

Now, a little biofilm isn't gonna hurt you.

一点点生物膜不会有什么伤害。

Biodegradable carbon-based electrodes printed on a piece of paper are covered with a layer of fluid called the biofilm.

可降解的碳源电极被印在一张纸上，并覆盖了一层叫做生物膜的可流动薄膜。

An absence of biofilms means fouling will never get going in the first place.

没有生物膜意味着从一开始就不会产生污垢。

Researchers say when mass-produced, this biofilm device will cost just over 1 dollar.

研究人员称，当此生物膜检水设备大规模生产时，每个只售一美元多一点。

But in reality, microbes gather by the millions to form vast communities known as biofilms.

但实际上，微生物以数百万计地聚集，形成一种叫做生物膜的巨大组织。

However, in a biofilm, the extracellular matrix shields microbes from external threats.

但是，如果生活在生物膜中，细胞外基质能够为微生物提供保护。

Additionally, indwelling medical devices should be removed and replaced when there is suspicion of biofilms.

此外，当怀疑有生物膜形成时，应拆除并更换留置的医疗设备器械。

It can also colonize indwelling medical devices, where it forms biofilms.

它还可以在留置的的医疗器械上定植，并形成生物膜。

To see how biofilms come about, let's watch one as it develops on a submerged river rock.

为了了解生物膜如何产生，我们以一个生长在河石上的生物膜为例。
