Before agar, microbiologists had experimented with other foodstuffs as microbial media. They turned to substances rich in the starches, proteins, sugars, fats, and minerals that organisms need for growth, testing with broths, bread, potatoes, polenta, egg whites, coagulated blood serums, and gelatine. However, none worked particularly well: all were easily broken down by heat and microbial enzymes, and their surface, once colonized, became mushy and unsuitable for isolating microbes.
Elsewhere, the S26 Ultra runs on the same chipset as its smaller siblings. It comes with 12 or 16GB of RAM and 256GB, 512GB or 1TB of storage. The battery is larger than the ones in the other S26 models, as the Ultra has a 5,000 mAh capacity. There's support for Super Fast Charging 3.0 as well. Alas, Samsung still hasn't seen fit to offer built-in Qi2 charging magnets in the S26 lineup, which seems like a wild oversight in the year 2026.
