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.

Why we like itMost of the time, we see really stellar TV deals sell out as fast as they appeared. That's not the case for the 75-inch Hisense U7 Mini LED TV. We featured this "ultimate mid-premium" model from 2025 last week, but it's still down to just $899.99 at Amazon if you missed it. It's list price is actually near $2,000 (which you can see on the Best Buy website), which means this is an even bigger deal than Amazon is letting on. Standout features of the U7 include Mini LED backlighting with an AGLR-Antiglare low-reflection panel, up to 3,000 nits of brightness, and HDR10, HDR10+ Adaptive, HLG, Dolby Vision IQ and Dolby Atmos. Plus, it features an impressive 165Hz refresh rate, which makes it a top pick for gamers.
