Additional Selective and Differential Cell Culture Media
NEOGEN Lauryl Sulfate Broth, 500 g
Lauryl Sulfate Broth is used for the detection of coliform bacteria in water and wastewater in a laboratory setting. Lauryl Sulfate Broth is not intended for use in the diagnosis of disease or other conditions in humans.The coliform group of bacteria includes aerobic and facultative anaerobic, Gram-negative, non-sporeforming bacilli that ferment lactose and form acid and gas at 35°C within 48 hours. Members of the Enterobacteriacae comprise the majority of this group, but organisms such as Aeromonas spp. may also be included. Procedures to detect and confirm coliforms are used in testing water, foods, dairy products, and other materials.Lauryl Sulfate Broth, also referred to as Lauryl Tryptose Broth, is prepared according to the formula of Mallmann and Darby. During their investigation, Sodium Lauryl Sulfate produced the best results for inhibition of organisms other than coliforms.

NEOGEN Buffered Peptone Water (BPW), 10 kg
Buffered Peptone Water (BPW) is used for the non-selective pre-enrichment of Salmonella spp. from food and is not intended for use in the diagnosis of disease or other conditions in humans. Edel and Kamelmacher found that food preservation techniques involving heat, desiccation, preservatives, high osmotic pressure, or pH changes cause sublethal injury to Salmonella spp. Preenrichment in a non-selective medium allows for repair of cell damage and facilitates the recovery of Salmonella. Lactose Broth is frequently used for this purpose, but it may be detrimental to recovering Salmonellae. Buffered Peptone Water maintains a high pH over the pre-enrichment period and allows in repair of injured cells that may be sensitive to low pH. This is particularly important for vegetable specimens which have a low buffering capacity. Buffered Peptone Water is used in standard methods.

NEOGEN UVM Broth, 500 g
This item has a minimum qty of 2 per supplier requirements.
UVM Broth is used for the selective enrichment of Listeria spp and is not intended for use in the diagnosis of disease or other conditions in humans.UVM Broth is a modification of the formula described by Donnelly and Baigent. This formula is used for the selective enrichment of Listeria spp. from food samples. Listeria spp. grow over a pH range of 5.0 - 9.6 and survive in food products with pH levels outside these parameters. Listeria spp. are microaerophilic, Gram-positive, asporogenous, non-encapsulated, non-branching, short, motile rods. Motility is pronounced at 20°C. Identification of Listeria is based on successful isolation of the organism, biochemical characterization, and serological confirmation.For more information visit https://www.neogen.com/solutions/Microbiology/uvm-broth
NEOGEN Sabouraud Dextrose Agar, 5 kg
Sabouraud Dextrose Agar is used for the cultivation of fungi. Conforms to Harmonized USP/EP/JP performance requirements and is not intended for use in the diagnosis of disease or other conditions in humans. A medium recommended by the Harmonized Pharmacopeia for the isolation and identification of Candida albicans from non-sterile samples. Conforms to USP/EP/JP performance specification. The medium is commonly abbreviated to SDA. The medium is also used for the preparation and maintenance of fungal test strains as described by the Harmonized Pharmacopeia. The peptone digests and dextrose provide a nutritious base for luxuriant fungal growth and the acidic pH affords selectivity against bacteria. Due to the high carbohydrate content and low pH this medium is highly sensitive to overheating which will cause a drop in the gel strength.For more information visit https://www.neogen.com/solutions/Microbiology/sabouraud-dextrose-agar
NEOGEN Tryptic Soy Agar with Lecithin and Tween 80, 500 g
Tryptic Soy Agar with Lecithin and Tween 80 is used for the isolation of microorganisms from surfaces sanitized with quaternary ammonium compounds and is not intended for use in the diagnosis of disease or other conditions in humans. In 1955, Leavitt et al. discovered Tryptic Soy Agar supported excellent growth of aerobic and anaerobic microorganisms. Tryptic Soy Agar is a nutritious base and a variety of supplements are added to enhance the medium, including Lecithin and Tween 80. The Lecithin and Tween 80 inactivate some preservatives that may inhibit bacterial growth, reducing “preservative carryover”. Tryptic Soy Agar with Lecithin and Tween 80 is recommended for determining the sanitation efficiency of containers, equipment, and work area (environmental monitoring).For more information visit https://www.neogen.com/solutions/Microbiology/tryptic-soy-agar-with-lecithin-and-tween-80
NEOGEN Violet Red Bile Glucose Agar (VRBGA), 500 g
Violet Red Bile Glucose Agar is used for the enumeration of Enterobacteriaceae in foods. Violet Red Bile Glucose Agar conforms to Harmonized USP/EP/JP requirements and is not intended for use in the diagnosis of disease or other conditions in humans. A medium recommended by the Harmonized USP/EP/JP for isolation and identification of bile-tolerant Gram-negative bacteria from non-sterile products. Conforms to Harmonized USP/EP/JP performance specification. Yeast extract provides vitamins and gelatin serves as source of carbon and nitrogen. Glucose is a fermentable carbohydrate and sodium chloride maintains the osmotic balance. Bile salts and crystal violet act as selective agents inhibiting many Gram-positive bacteria. The formulation is a modification of Violet Red Bile Agar by Mossel which substitutes lactose for glucose.For more information visit https://www.neogen.com/solutions/Microbiology/violet-red-bile-glucose-agar
NEOGEN Hektoen Enteric (HE) Agar, 500 g
Hektoen Enteric Agar is used for the isolation and differentiation of enteric pathogens. Hektoen Enteric Agar is not intended for use in the diagnosis of disease or other conditions in humans. Hektoen Enteric Agar was developed in 1967 by King and Metzger. Compared to other enteric differentiating media commonly used, Hektoen Enteric Agar increased the isolation rate of Salmonella spp. and Shigella spp. This was accomplished by increasing the carbohydrate and peptone content of the medium in order to counteract the inhibitory effects of bile salts and indicators. King and Metzger formulated a medium that slightly inhibited growth of Salmonella and Shigella, while inhibiting Gram-positive microorganisms. Enzymatic Digest of Animal Tissue provides nitrogen, carbon, and amino acids required for organism growth.For more information visit https://www.neogen.com/solutions/Microbiology/hektoen-enteric-agar
