Hi guys. I'm Catie Wayne. And this is 'Animalist News.'
嗨，朋友们 我是Catie Wayne 这里是动物学人新闻
We humans have been using yeast to make bread, beer, and wine for over 5,000 years.
我们常常用酵母来做面包，啤酒和白酒 已经有5000年历史了
And many humans would agree that alcohol and beer in particular is delicious.
很多人对啤酒是美味深以为然
Yeast, a bunch of microorganisms in the fungi family, is fundamental in the brewing process.
酵母——是霉菌种群中的一种一大团微生组织是发酵过程的基础
It creates the alcohol and carbon dioxide, which makes beer bubbly, obvi.
它们发酵产生二氧化碳产生了啤酒的泡泡。
But the rule of yeast is a little more complicated than that.
但是发酵的规律比这个更复杂
Yeast cells also produce aroma compounds that are essential for the flavor and taste of the beer.
酵母也会产生芳香化合物 那是啤酒尝起来很香的根本原因
But one might wonder why yeast cells produce these aroma compounds that make beer so delightful.
那么问题来了，为什么酵母会产生这些 香味化合物使啤酒如此美味
I mean, it certainly isn't so bearded men everywhere can make that satisfactory ah noise after taking a swig of their favorite beer. Ah.
我的意思，当然不是胡须男在在痛饮一杯最爱的啤酒之后发出满足的一声啊哈
That is some sweet aroma compounds.
这是一种甜的香味
Well, according to a recent study by VIB, the Flanders Institute for Biotechnology,
好的，通过vib最近的研究 那是Flanders生物科技研究机构
these aroma compounds appear to have evolved specifically to attract fruit flies-- much in the same way flowers attract bees —
这些香味化合物看起来吸引了果蝇，和花吸引蜜蜂是同样的方式
so that these yeast cells can hitch a ride on the flies and spread their genetic material elsewhere.
那就是酵母君搭果蝇的便车 传播它的遗传物质到各个地方
In other words, it would appear that we have fruit flies to thank for the taste of beer.
换句话说，显然我们要为我们尝到美味的啤酒感谢果蝇
So, I tip my fedora to you, flies.
所以，我为你点赞，果蝇
Does this make you suddenly love fruit flies?
这会使你突然爱上果蝇吗？
