Tomato Juice Agar, prepared according to Kulp and White’s modification, is especially useful in cultivating L. acidophilus from foodstuffs.For more information visit https://www.neogen.com/solutions/Microbiology/tomato-juice-agar
NEOGEN Mycobiotic Agar, 500 g
Mycobiotic Agar is used for the selective isolation of fungi in a laboratory setting. Mycobiotic Agar is not intended for use in the diagnosis of disease or other conditions in humans. The value of selective media for initial cultivation of pathogenic fungi has been demonstrated by numerous investigators. Historically, media for fungi generally relied on an acid pH to make the media less suitable for growth of many bacteria. Recently developed media use neutral or slightly alkaline reactions, antibiotics, bile salts, and dyes as selective agents against bacteria. Mycobiotic Agar is an excellent basal medium and antifungal agents, cycloheximide and chloramphenicol, are added to study their affect on fungi. This medium is proven useful in the isolation of dermatophytes and other fungi from samples.For more information visit https://www.neogen.com/solutions/Microbiology/mycobiotic-agar
NEOGEN m-HPC Agar, 500 g
m-HPC Agar is used for the enumeration of heterotrophic organisms in water by the membrane filtration technique in a laboratory setting. m-HPC Agar is not intended for use in the diagnosis of disease or other conditions in humans.m-HPC Agar, also known as m-Heterotrophic Plate Count Agar, was developed by Taylor and Geldreich in 1979. Monitoring the levels of heterotrophic bacteria, those microorganisms that can grow on minimal organic nutrients, is currently performed to indicate problems with treatment methods within distribution systems. There is evidence that heterotrophic bacteria are not hazardous to healthy individuals, but may be opportunistic pathogens capable of infecting individuals with impaired immune systems.m-HPC Agar is used in standard methods for the detection of heterotrophic bacteria using the membrane filtration technique.For more information visit https://www.neogen.com/solutions/Microbiology/m-hpc-agar
NEOGEN Harlequin Tryptone Bile Glucuronide Agar (TBX), 500 g
Harlequin Tryptone Bile Glucuronide Agar (TBX) is used for the enumeration of E. coli in food and animal feed and is not intended for use in the diagnosis of disease or other conditions in humans. Tryptone Bile Glucuronide Agar is recommended by ISO 16649-1:2001, ISO 16649-2:2001 and ISO 16649-3:2015 for enumeration of β-glucuronidase positive Escherichia coli in products intended for human consumption or for the feeding of animals. The medium contains tryptone as a source of nitrogen and amino acids, bile salts act as a selective against Gram-positive organisms and agar is the gelling agent. 5-bromo-4-chloro-3-indolyl-β-D-glucuronide (X-glucuronide) is a chromogen for the detection of the β-D-glucuronidase enzyme which is present in most E. coli* but not other coliforms.*96-97% of E.coli are β-D-glucuronidase positive. A notable exception is E. coli O157:H7 For more information visit https://www.neogen.com/solutions/Microbiology/harlequin-tryptone-bile-glucuronide-agar-tbx
NEOGEN Harlequin mLGA, 500 g
Membrane Lactose Glucuronide Agar (mLGA) is a medium for the detection and identification of E. coli and coliforms from water samples and is not intended for use in the diagnosis of disease or other conditions in humans.Traditionally, membrane Lauryl Sulphate Broth (mLSB) has been used as the standard media for isolating coliforms (including E. coli) from water potentially contaminated with sewage. Harlequin membrane Lactose Glucuronide Agar (mLGA) is a modification of mLSB aimed at reducing costs by reducing the number of filters used per test sample and aiding in the recovery and identification of coliforms and E. coli. The medium has been modified from the mLSB formulation by the incorporation of X-glucuronide (BCIG), sodium pyruvate and agar.*96-97% of E. coli strains positive.

NEOGEN Terrific Broth, Modified, 500 g
Terrific Broth, Modified is used with glycerol in cultivating recombinant strains of Escherichia coli in a laboratory setting. Terrific Broth, Modified is not intended for use in the diagnosis of disease or other conditions in humans. Terrific Broth, Modified was developed by Tartoff and Hobbs to increase yields of plasmid DNA from transformed E. coli and is a popular choice of media available for plasmid preps. While cells grown in Terrific Broth, Modified can grow slower than other liquid media, the final cell density and plasmid yields are 2 – 4 fold higher. The higher yield is a result of the increased concentration of Enzymatic Digest of Casein and Yeast Extract in this formula. Glycerol is used as a carbohydrate source, and unlike glucose, is not fermented to acetic acid.For more information visit https://www.neogen.com/solutions/Microbiology/terrific-broth-modified

NEOGEN Letheen Broth with Tween, Modified, 10 kg
Letheen Broth with Tween, Modified is used for the recovery of microorganisms from cosmetics in a laboratory setting and is not intended for use in the diagnosis of disease or other conditions in humans.In 1948, Weber and Black described the value of a highly nutritional solid medium containing neutralizing agents for quaternary ammonium compounds in sanitizers. The addition of Lecithin and Polysorbate 80 to Tryptone Glucose Extract (TGE) Agar resulted in a medium that effectively neutralizes quaternary ammonium compounds in testing of germicidal activity. Total neutralization of disinfectants is critical as disinfectant residues can result in a false negative (no-growth) test result.Letheen Broth with Tween, Modified is based on the formula described in FDA Bacteriological Analytical Manual, and a modification of Letheen Broth Base.For more information visit https://www.neogen.com/solutions/Microbiology/letheen-broth-with-tween-modified

NEOGEN Raka-Ray No. 3 Agar, 5 kg
Raka-Ray No.3 Agar is for the detection of lactic acid bacteria in beer and for monitoring in-process beer quality, and is not intended for use in the diagnosis of disease or other conditions in humans. It is recommended for this application by the European Brewing Convention (EBC) and the American Society of Brewing Chemists (ASBC).Contamination of beer and the beer making process by members of the lactobacilli family results in spoilage, primarily through their production of metabolic products which are detrimental to the flavor of the final product. Detection of these organisms is complicated by their diverse nutritional and environmental requirements.A number of different formulations have been described for the isolation of lactic acid bacteria in brewing products and processes. Raka-Ray Agar was developed by the addition of various growth promoting compounds to Universal Beer Agar.For more information visit https://www.neogen.com/solutions/Microbiology/raka-ray-3-agar
