小舅的命运，是这个家族伤痕中最沉重的一笔。年仅十七八岁的他曾被送入再教育营，度过一年光阴。在那里，他每天写检讨，凌晨四点起床去农场工作。关于他为何未被赎回，原因已湮没在混乱的时局中。
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.
