A dash of baking soda increases the Maillard reaction (a.k.a. the chemical process that creates a golden exterior) in recipes like zucchini bread and sugar cookies.
Aspergillus sp. growing in potato dextrose agar Potato dextrose agar (BAM Media M127) and potato dextrose broth are common microbiological growth media made from potato infusion and dextrose. Potato dextrose agar (abbreviated "PDA") is the most widely used medium for growing fungi and bacteria. PDA has the capability to culture various bacteria and fungi found in the soil. This agar can be ...
More immediately though, baking soda is not intended for eating. Being an alkali, it can froth in the stomach acid (think those baking-soda-and-vinegar volcanoes) and cause dogs to feel really ill.
Vinegar (dilute acetic acid), especially white vinegar, is also a common acidifier in baking; for example, many heirloom chocolate cake recipes call for a tablespoon or two of vinegar. [49] Where a recipe already uses buttermilk or yogurt , baking soda can be used without cream of tartar (or with less).
In order to prepare 1 liter of the Farrell's medium, the following quantities are added to 1 liter of serum dextrose agar: polymyxin B sulfate (5000 units =5 mg), bacitracin (25,000 units = 25 mg), natamycin (50 mg), nalidixic acid (5 mg), nystatin (100,000 units), and vancomycin (20 mg).
Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse), typically at a 5–10% concentration. BAPs are enriched, and differential media is used to isolate fastidious organisms and detect hemolytic activity. β-Hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony.
Here, the inoculum is added to the molten agar before pouring the plate. The molten agar is cooled to about 45 degrees Celsius and is poured using a sterile method into a petri dish containing a specific diluted sample. From here, the plates are rotated to ensure the samples are uniformly mixing with the agar.
On Potato Dextrose agar, colonies are white with a silky texture and a peach-coloured underside. [ 10 ] [ 16 ] Microsporum audouinii can be differentiated from non-sporulating strains of the similar M. canis by culture on autoclaved rice.
