Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.

卢晓中将其比作“鲇鱼”，认为它们为老牌研究型大学提供了改革参照，激活了发展活力。从更长远的视角看，传统与新型研究型大学的差异会随着改革而淡化。一方面，新型研究型大学会逐步成长为一流研究型大学；另一方面，北大、清华等老牌研究型大学正主动向“新型”靠拢，通过设立书院制、学科交叉融合等方式加速变革。“新型研究型大学最终会成为过渡性概念。”卢晓中说道。
