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.
中东地区对全球半导体，尤其是AI产业的重要性，已从单纯的“消费者”演变为“不可或缺的基础设施提供者”。人工智能的竞争归根结底是能源的竞争。随着大语言模型的训练需求不断推高电网负荷，像中东这样能够同时提供极低成本能源、大量资本以及相对灵活监管环境的地区，将成为AI工业化的主战场 。
