NEOGEN Buffered Peptone Water (BPW), 5 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 Sabouraud Dextrose Agar, 500 g
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
