What’s the lively as liveliest part of your kitchen, in terms of harboring bacteria? Is it the cutting board, ? The dish bunch, sponge? Or maybe your coffee maker. coffeemaker? Because even though caffeine has antibacterial effects, it turns out that espresso machines can harbor a whole menagerie of bacteria , - including some pathogenic species , more commonly associated with the toilet.

Researchers sampled ten Nespresso brand espresso machines. , zeroing in on an the drip trays, which catch those last drops of bround brown gold after a brew. They found that 9 nine of 10 the ten machines harbored residues rich in Enterococcus bacteria, a typical marker of human feagle fecal contamination. And another typical common resident was Pseudomonas , - which have has both benign and pathogenic strains. Pseudomonas appears to thrives thrive in the presents presence of caffeine, and even breaks it down. Which suggest suggests the bugs might be put to work , decaffeinating coffee, or cleaning caffeine residues from our water wayswaterways. The findings appear in the journal of Scientific Reports.

As for your next espresso shot, ? Don’t worry too much. The researchers did not find any bacteria in the coffee pots pods themselves . - so they say our fingertips might be the to blame for spreading the single soles than datasingle-celled invaders. And they write that it’s absolutely not the case that espresso Nespresso machines are dangerous for human health. Just wash the drip tray more often with soap and water. , just as you would any other food-contaminated surface. So that the only thing that is brewing in your espresso machine , is your coffee.

你厨房里最有生机的地方是哪儿啊,我是说附着的细菌呐?切菜板?刷碗的海绵? 或许,你的咖啡机? 因为即便咖啡因有抗细菌的效果,有研究显示浓缩咖啡机能附着一群细菌——包括一些和厕所马桶有关的致病菌相类似的致病菌呢。

研究人员们对10台Nespresso牌的浓缩咖啡机进行采样,主要范围集中在水盘,那里在煮咖啡之后有些残留暗金色的液滴。他们发现,10台机器中有9台,残留物里含有Enterococcus肠球菌属的细菌,一种人类粪便污染物被细菌感染的标志。另一种Pseudomonas假单胞菌属细菌——则有的是无害的,有些是致病的菌种被发现残留。假单胞菌在有咖啡因存在的情况下会大量繁殖,然后分解咖啡因。这种特性提示我们也许可用它进行去咖啡因咖啡的制作,或者从我们的排水口中清除咖啡因。该研究结果发表在《科学报告》杂志上。

关乎你的下一次煮咖啡嘛?别太担心了。研究人员在咖啡包里没有发现任何种类细菌——因此他们表示我们指尖也许对扩散此类单细胞生物有促进作用。然后他们写道,这绝对不是说浓缩咖啡剂对人类的健康有害。只需要像担心你的其它食物表面会被污染一样,经常用肥皂水清洗一下滴水盘。 所以之后,你的咖啡机里就只有一种你想要煮的,咖啡啦。
