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.
平台的適老化改造不能再停留在「放大字體」的表面功夫。賈煜建議，「政府可以出台相關規範，引導平台對老年人賬號實施『反成癮機制』；關閉『無限滾動』功能，每隔一段時間強制彈出休息提示。」在支付環節，針對60歲以上用戶的大額消費應當建立「冷靜期」或「親情賬戶二次確認」機制。
