Buffered Listeria Enrichment Broth (BLEB) Base Wide Mouth Glass Jars

Packaged in a convenient 12 oz wide mouth glass jar, this base format provides easy access for adding the required selective supplements and facilitates efficient pouring into enrichment vessels during sample preparation workflows. The wide mouth opening simplifies media preparation and reduces spill risk during supplement addition and dispensing, while the glass construction ensures superior chemical resistance, thermal stability, and compatibility with autoclaving for supplement incorporation. As a base formulation, this medium requires the addition of selective agents (such as acriflavine, nalidixic acid, and cycloheximide) to achieve full selective enrichment capability for Listeria isolation from food matrices with high background microflora. The buffering system maintains optimal pH conditions throughout the enrichment period, preventing pH shifts that could inhibit Listeria recovery while allowing gradual resuscitation of stressed organisms commonly encountered in processed food samples. This product is intended for food safety testing applications and is not designed for the diagnosis of human disease.
