A little aquatic microbe called a cyanobacterium drifts by.

一种叫做蓝藻的水生微生物漂过。

A toxic flowering of " cyanobacterium" was found in seasonal water sources in the area.

在该地区的季节性水源中发现了有毒的“蓝藻细菌”。

Once the cyanobacterium is fully engulfed, it's inside you, surrounded by a bubble of your own membrane.

一旦蓝藻被完全吞没，它就到了你体内，被你自己的膜泡包围着。

It's not like botanists were around over a billion years ago when that humble, hungry, single-celled organism stumbled upon that cyanobacterium.

十多亿年前，当那个卑微、饥饿的单细胞生物偶然发现蓝藻时，植物学家们并不在场。

Hundreds of millions of years ago, some other prehistoric microbe swallowed a cyanobacterium whole in a process called endosymbiosis.

数亿年前，其他一些史前微生物在称为内共生的过程中吞噬了整个蓝藻。

The aim was to find out why the animals had died. The test results suggested that the elephants died from cyanobacterium, or blue-green algae, poisoning.

目的是找出大象的死因。测试结果表明，大象死于蓝藻或蓝绿藻中毒。

But instead of bursting the bubble to digest it, something weird happens — the cyanobacterium just hangs out inside you and keeps photosynthesizing, providing you with a steady supply of sugar.

但奇怪的事情发生了——蓝藻只是在你体内徘徊，继续进行光合作用，为你提供稳定的糖供应。
