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.

The snow is melting, the days are getting longer, and I can almost smell the springtime ahead. Soon, we'll be cruising around town on ebikes and electric scooters instead of burning fossil fuels. For now, the weather hasn't quite caught up, which is great for markdowns. Many of the best electric scooters are still seeing significant discounts. If you've been thinking about buying one, now's the best time: prices are low, and sunny commuting days are just ahead.
