New-ish year, new Samsung phones. Let's deal with the out-and-out bad news first. The S26 and S26+ are each $100 more expensive than their predecessors (the RAM shortage isn't exactly helping to keep prices down). They start at $900 and $1,100, respectively, for variants with 256GB of storage.
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.
