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.
遂想起王安石所言：“贫者不得行礼，贵者得行无礼。”——意思是，普通人有心无力，对天下风俗礼仪，即便想认真隆重，也起不了什么作用；而有权有钱人有条件，却恰恰不带头淳化隆厚风习礼俗，反而争相毁弃文雅、蔑视礼仪，甚至不以粗鄙为耻，反以为荣。这是很危险的，王荆公将此列为末世风俗。
