Palcam Agar
Palcam Agar is used for the selective isolation and enumeration of Listeria monocytogenes from foods and environmental samples. Columbia Blood Agar Base is a general-purpose growth medium. Mannitol and Phenol Red have been added to differentiate Mannitol-fermenting strains of possible contaminants. Polymyixin B, Acriflavin, Ceftazidime, and Lithium Chloride are selective agents used to suppress the growth of Gram-negative and certain Gram-positive bacteria. Esculin and Dextrose are the main energy sources for bacterial growth. Members of the Listeria group hydrolyze Esculin to 6,7-dihydroxycoumarine, which reacts with Ferric Ammonium Citrate and results in the blackening of the medium. Agar is the gelifying agent. There is a choice of 3 sizes - 500g, 2kg, and 10kg.
PREPARATION: Mix 74 grams of the medium in one liter of purified water until evenly dispersed. Heat with repeated stirring to dissolve completely. Distribute and autoclave at 121°C for 15 minutes. Cool to 45-50°C. Aseptically add sterile solution of Polymyixin B 10mg/L, Acriflavin 5.0mg/L and Ceftazidime, 20mg/L.

Not for side sleepers
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
These pillows are quite soft and flat, and offer very little support. I sleep on my side and can't use these pillows. I don't know why they're recommended for side sleepers.

A pillow made of extras soft lumps and clumps. Defective.
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
This pillow should not even be sold. It's simple a super soft pillow with lumps of clumps of softness. Part of my head was even touching the mattress through the clumps. I ended up throwing it on the floor at 2 am and my head and neck hurt from it. I have never had a pillow of lumps before. I hope I can return this thing.

Super comfortable!!!!
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.
