This was not the first time that microbiologists experienced problems with agar. A phenomenon called “The Great Plate Count Anomaly” baffled researchers in the early 20th century when they observed that the number of cells seen under a microscope didn’t match the actual number of colonies growing on an agar plate. Investigating this discrepancy, researchers found agar itself to be the culprit: when nutrient broths are heated with agar during boiling, harmful byproducts (hydroperoxide) can form due to the reaction of agar with phosphate minerals contained in the media. Researchers can avoid this by autoclaving agar separately from the nutrient broth, or by reducing the amount of agar used.

第三方驿站大家对于驿站的印象基本都是从菜鸟驿站开始的，而菜鸟驿站就是阿里为了解决快递的最后一公里问题而发展的管理网络。早期菜鸟最先瞄准的是校园，帮助快递解决进校园的难题。后来菜鸟能发家，很大程度是归功于淘宝上庞大的用户体量和下单量，所以菜鸟驿站和淘宝购物联通也就梳理成章，这也就是为什么我们最早看到的驿站几乎都是菜鸟驿站。但本质上，菜鸟和淘宝并不是同一家公司，对快递公司来说就更是如此——菜鸟驿站其实就是一个第三方平台，只是因为联动了淘宝所以看起来拿到了很多家快递公司的快递。
