NEOGEN Sabouraud Dextrose Agar, Emmons, 500 g
Sabouraud Dextrose Agar, Emmons is used for the cultivation of fungi in a laboratory setting. Sabouraud Dextrose Agar, Emmons is not intended for use in the diagnosis of disease or other conditions in humans. Sabouraud Dextrose Agar (SDA), Emmons is a modification of Dextrose Agar described by Sabouraud. SDA is used for cultivating pathogenic and commensal fungi and yeasts. Emmons modified the formula by adjusting the pH and reducing the dextrose concentration. This neutral pH enhances recovery of some pathogenic fungi. Sabouraud Dextrose Agar, Emmons is an excellent basal medium, and antibiotics and inhibitors may be added for the selective cultivation and isolation of various microorganisms.For more information visit https://www.neogen.com/solutions/Microbiology/sabouraud-dextrose-agar-emmons

NEOGEN Lowenstein-Jensen Medium, 5 kg
Lowenstein - Jensen Medium is used with fresh egg and glycerol for the isolation and differentiation of Mycobacterium spp. in a laboratory setting. Lowenstein - Jensen Medium is not intended for use in the diagnosis of disease or other conditions in humans.The use of egg-based media for primary isolation of mycobacteria have two significant advantages. First, egg-based media support a wide variety of mycobacteria. Second, growth of mycobacteria on egg media can be used for niacin testing. Liquefaction of Lowenstein-Jensen Medium can occur if contaminated with proteolytic organisms.Lowenstein-Jensen Medium is a modification of Lowenstein Medium, modified by Jensen. Jensen modified the medium by alternating the citrate and phosphate contents, eliminating congo red dye, and increasing malachite green concentration.For more information visit https://www.neogen.com/solutions/Microbiology/lowenstein-jensen-medium
NEOGEN Terrific Broth, Modified, 10 kg
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 Vogel Johnson Agar, 500 g
Vogel Johnson Agar is used for the isolation of staphylococci in a laboratory setting. Vogel Johnson Agar is not intended for use in the diagnosis of disease or other conditions in humans. Coagulase-positive staphylococci, primarily Staphylococcus aureus, are among the microorganisms that cause spoilage or chemical changes in cosmetic products. To isolate coagulase-positive, mannitol fermenting staphylococci, Vogel and Johnson modified Tellurite-Glycine Agar by Zebovitz, Evans, and Niven. The modification included increasing mannitol and adding a pH indicator. Vogel Johnson Agar selects and differentiates coagulase-positive staphylococci that ferment mannitol and reduce tellurite. Vogel Johnson (VJ) Agar is specified in standard methods testing for cosmetics and nutritional supplements.For more information visit https://www.neogen.com/solutions/Microbiology/vogel-johnson-agar
NEOGEN Brilliant Green Agar, 10 kg
Brilliant Green Agar is used for the selective isolation of Salmonella spp. in a laboratory setting. Brilliant Green Agar is not intended for use in the diagnosis of disease or other conditions in humans.Kristensen, Lester, and Jurgens first described the use of Brilliant Green Agar as a primary plating medium for the isolation of Salmonella. The report described the medium as useful for the differentiation of “paratyphoid B” from other intestinal gram-negative bacilli. Kaufmann modified their formula and used Brilliant Green Agar in addition to Tetrathionate Broth for the isolation of Salmonella from stool specimens. The outstanding selectivity of this medium permits use of moderately heavy inocula, which should be evenly distributed over the surface. Brilliant Green Agar is used in the microbial limits test. Brilliant Green Agar supplemented with novobiocin is used in food testing.For more information visit https://www.neogen.com/solutions/Microbiology/brilliant-green-agar-ncm0283

NEOGEN m-HPC Agar, 5 kg
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
