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.
對於此次默茨訪華，麥永剛直接表示德國難有具體的成果：德企去風險化（derisking）的工作遠遠不足，卻需抵禦中國進口衝擊，不僅是汽車產業，德國的生物科技及化工產業情況都很險峻。他認為，有些長期在華德國人吸收了宣傳觀點，卻忽略西方經濟現實，成為「熊貓擁抱者」，其樂觀看法常誤導了在德國的總部。。业内人士推荐safew官方版本下载作为进阶阅读
