NEOGEN Bismuth Sulphite Agar, 5 kg
Bismuth Sulfite Agar is used for the selective isolation of Salmonella spp. In a laboratory setting. Bismuth Sulfite Agar is not intended for use in the diagnosis of disease or other conditions in humans and conforms to FDA/BAM formulation. Salmonellosis can result from consumption of raw, undercooked, or improperly processed foods contaminated with Salmonella. U. S. federal guidelines require various poultry products to be routinely monitored before distribution for human consumption. Bismuth Sulfite Agar is a modification of Wilson and Blair formula. The typhoid organism grows luxuriantly on the medium, forming characteristic black colonies. Gram-positive bacteria and coliforms are inhibited on Bismuth Sulfite Agar. The inhibitory action of Bismuth Sulfite Agar permits the use of a large inoculum, increasing the possibility of recovering pathogens that may be present in small numbers.For more information visit https://www.neogen.com/solutions/Microbiology/bismuth-sulfite-agar

Peptone, beef and yeast extract provide a source of nitrogen, essential vitamins and amino acids. Starch aids the detoxification of harmful metabolites and glucose is a fermentable carbohydrate. Sodium chloride provides osmotic balance and sodium acetate acts as a buffer. L-Cysteine hydrochloride acts as a reducing agent to create an anaerobic environment and maintain a low Eh.For more information visit https://www.neogen.com/solutions/Microbiology/reinforced-clostridial-medium
NEOGEN Lauryl Tryptose (LST) Broth, 5 kg
Lauryl Tryptose (LST) Broth is used for the detection of coliform bacteria in water and wastewater. Lauryl Tryptose Broth is not intended for use in the diagnosis of disease or other conditions in humans.Lauryl Tryptose Broth is a selective medium for the detection of coliforms in water, dairy products and other foods. The American Public Health Authority (APHA) recommend Lauryl Tryptose Broth for the Most Probable Number Presumptive Test of coliforms in waters, effluent or sewage and as a confirmation test of lactose fermentation with gas production from milk samples and for the detection of coliforms in foods.Lauryl Tryptose Broth is prepared according to the formulation of Mallmann and Darby. Mallmann and Darby showed that tryptose at a concentration of 2% increased the early logarithmic growth phase when compared to meat peptone.For more information visit https://www.neogen.com/solutions/Microbiology/lauryl-tryptose-broth
NEOGEN Yeast Extract, 5 kg
Yeast Extract is an autolysate of yeast cells used in preparing microbiological culture media in a laboratory setting. Yeast Extract is not intended for use in the diagnosis of disease or other conditions in humans.Yeast Extract is the water-soluble portion of autolyzed yeast. The autolysis is carefully controlled to preserve naturally occurring B-complex vitamins. Yeast Extract is prepared and standardized for bacteriological use and cell cultures and is an excellent stimulator of bacterial growth. Yeast Extract is generally employed in the concentration of 0.3% - 0.5%. Yeast Extract is typically prepared by growing baker’s yeast, Saccharomyces spp., in a carbohydrate-rich plant medium. The yeast is harvested, washed, and resuspended in water, where it undergoes autolysis, i.e., self-digestion using the yeast’s enzymes.For more information visit https://www.neogen.com/solutions/Microbiology/yeast-extract
NEOGEN Agar, Bacteriological No. 1, 5 kg
Agar, Bacteriological No. 1 is a solidifying agent for use in preparing microbiological culture media in a laboratory setting. Agar, Bacteriological No. 1 is not intended for use in the diagnosis of disease or other conditions in humans. Agar, Bacteriological No. 1 conforms with the testing specified in the USP/EP Pharmacopeia.Agar is a phycocolloid extracted from a group of red-purple algae, usually Gelidium spp. Agar was first suggested for microbiological purposes in 1881 by Fannie Hesse. By the early 1900’s, agar became the gelling agent of choice over gelatin because agar remains firm at growth temperature for many pathogens and agar is generally resistant to a breakdown by bacterial enzymes. The use of agar in microbiological media significantly contributed to the advance of microbiology, paving the way to study pure cultures.For more information visit https://www.neogen.com/solutions/Microbiology/agar-bacteriological-number-1
NEOGEN Columbia CNA Agar, 5 kg
Columbia CNA Agar is used with blood for the selective isolation of Gram-positive cocci in a laboratory setting. Columbia CNA Agar is not intended for use in the diagnosis of disease or other conditions in humans.Ellner et al. described Columbia CNA Agar as a variation of Columbia Blood Agar Base that is selective for Gram-positive cocci. Colistin and Nalidixic Acid are added to the formula, selecting for Gram-positive organisms and fungi by suppressing Gram-negative bacteria.For more information visit https://www.neogen.com/solutions/Microbiology/columbia-cna-agar
NEOGEN APT Agar, 5 kg
APT Agar is used for the cultivation of heterofermentative lactobacilli in a laboratory setting. APT Agar is not intended for use in the diagnosis of disease or other conditions in humans.Evans and Niven investigated the cultivation of heterofermentative lactobacilli, causing the faded or green discoloration of cured meat products. Deibel, Evans, and Niven tested thiamine-requiring bacteria, specifically Lactobacillus viridescens. Their formulations led to the development of APT Agar.Lactic acid bacteria, a group of acid-producing bacteria, include the genera Streptococcus, Leuconostoc, Pediococcus, and Lactobacillus. These organisms are widespread in nature, associated with bacterial spoilage of foods including dairy products, meat, and vegetables. APT Agar is used for cultivating heterofermentative lactic acid bacteria from food products.For more information visit https://www.neogen.com/solutions/Microbiology/apt-agar
NEOGEN Letheen Agar Base Modified without Tween, 5 kg
Letheen Agar Base Modified (without Tween) is used with Tween 80 (Polysorbate 80) for the isolation of microorganisms from cosmetics in a laboratory setting. Letheen Agar Base Modified 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 Tween 80 (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. Disinfectant residues can result in a false negative (no-growth) test.For more information visit https://www.neogen.com/solutions/Microbiology/letheen-agar-base-modified-without-tween
NEOGEN Bile Salts No. 3, 5 kg
