在皮氏细菌培养皿内，细菌数量的增长模式是典型的“S”曲线。
THE population of bugs in a Petri dish typically increases in an S-shaped curve.
他们使用的“画布”很小——只有几厘米直径的圆形培养皿，所以就只能使用很小的“画笔”来蘸取少量细菌，然后涂布在培养基上。
Using a small paintbrush dipped in the bacteria, they are painstakingly 'painted' onto the tiny canvas - a petri dish only a few centimetres wide.
弗莱明注意到，在发霉的培养皿中没有生长任何细菌，由此，他发现了第一种抗生素。
Fleming noticed that Petri dishes with mould on them grew no bacteria, and in doing so discovered the first antibiotic.
他们在一个不锈钢培养皿里培育细菌，然后用激光蒸发它们的信号分子，把这些分子导入到质谱分析仪中并记录他们的状态。
They grow their bacteria on a stainless steel plate, and use a laser to vaporise their signalling molecules, feeding these into a mass spectrometer to catalogue the molecules present.
但当两种抗生素都计入培养基的时候，蓝色细菌几乎把黄色细菌清出地盘——培养皿。
But when both drugs were present, blue bacteria swept the field—or, rather, the Petri dish.
他们的成就包括人造血液，一种探测砷的生物传感器，以及能够在培养皿中像“有生命的计算机”那样解开数学难题的细菌。
Their accomplishments include artificial blood, a biological sensor to detect arsenic and bacteria that can act as "living computers" to solve mathematical problems in lab dishes.
弗莱明(上图)是细菌学教授，那次他外出度假前，把几个装有他研究的金黄色葡萄球菌的培养皿忘在了自己实验室的桃花心木工作台上。
Going on holiday, Fleming (above), then a professor of bacteriology, left several Petri dishes containing staphylococci, which he had been studying, on the mahogany workbench of his lab.
五分钟后，等离子火炬杀死了皮氏培养皿中99%的细菌，而十分钟后，它杀死了老鼠伤口上90%的细菌。
After five minutes, the plasma torch killed 99 percent of bacteria grown in a Petri dish, and after ten minutes, it killed 90 percent of bacteria present in the wounds of a rats.
研究人员说，治疗感染可以通过加入更多的细菌来做到，并指出，他们在皮氏培养皿外用骗术破坏了微生物间的合作。
Infections could be treated by adding more bacteria, say researchers who have shown that cooperation between microbes is undermined outside the bounds of the Petri dish by a few 'cheats'.
玻璃。装细菌用玻璃器皿。“陪氏”培养皿。
他发现了一种在培养皿中生长的物质(不久后被命名为青霉素)杀死了细菌，当代的抗生素开始登上历史舞台。
He found a substance (later named penicillin) growing on it that killed the bugs, and modern-day antibiotics got its start.
