By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
陆逸轩：这肯定是我这辈子经历过的最大压力。即便从一个相对客观的角度来说，因为我之前在肖赛已经得过奖，再加上利兹比赛的一等奖，可以说在比赛的层面上，没有哪个钢琴家曾经面对过这种程度的压力。就获奖而言，那是一种“输不起”的状态，这种心理负担是非常真实的。准备过程中，我从来没有完全下定决心要参赛。2025年4月份，也就是5月要公布参赛名单之前，我大概有八成的倾向是不想去，只有两成是想去的。后来即便已经到了华沙，我也想退赛，尤其是在第三轮前。
