Oxford Listeria Agar Base
Oxford Listeria Agar, with addition of antibiotics, is used for the selective isolation of Listeria monocytogenes from food. This medium is utilized with a Ferric Ammonium Citrate supplement for the rapid detection of L. monocytogenes from food and environmental samples. Columbia Blood Agar Base is a general-purpose growth medium. Esculin is the main energy source. All members of the Listeria spp. hydrolyze Esculin to 6,7-dihydroxycoumarine. This compound reacts with Ferric Ammonium Citrate, resulting in the blackening of the medium. Selectivity for Listeria is achieved through the Lithium Chloride included in the formulation and the addition of sterile antimicrobiotic supplements. L. monocytogenes is typically visible after 24 hours, but continued incubation may allow for the detection of slower growing strains. There is a choice of 3 sizes - 500g, 2kg, and 10kg.
PREPARATION: Mix 57.5 grams of the medium in one liter of purified water until evenly dispersed. Heat with repeated stirring and bring to a boil to dissolve completely. Distribute and autoclave for 15 minutes at 121°C. Aseptically add a filter sterilized solution of Oxford Antimicrobic Supplement (Acriflavin 5mg, Cefotetan 2mg, Colistin Sulfate 20mg, Cycloheximide 400mg, and Phosphomycin 10mg) or Modified Oxford Antimicrobic Supplement (Colistin Sulfate 10mg, Moxalactam 20mg).

Sturdy

Love the shelves. Nice touch to my bathroom. Easy enough to install. They're not holding anything too heavy so can't speak too much on that but they do have a nice width.

Good for light stuff
Color: Black, Size: 15 inches, Color: Black, Size: 15 inches
Good product. Very light though and if it’s in dry wall won’t hold something really heavy. I don’t think it would hold 20 pounds just light. I put over my washer and dryer and put one right on top that way I can put heavy stuff on that side without it weighing down and being ripped out of the wall. I won’t be putting heavy stuff on the right side I used 4 pieces and the wall is about 60-62 inches long

Perfect sized floating shelves
Color: Black, Size: 24 inches, Color: Black, Size: 24 inches
These are great and the perfect width. I had my contractor install them because my tile had to have a hole drilled into it. I love that it looks seemless and flat to the tile. New bathroom renovation. I am very pleased. Holds a few towels also candles and a little plant with extra space. Perfect for a minimal look or if you have a small bathroom. Color was spot on.
