Used primarily in microbiological research to support the growth and isolation of bacteriophages that infect Bacteroides species, this medium provides optimal nutrients and environmental conditions for phage propagation. It is commonly applied in environmental monitoring, particularly in detecting fecal contamination in water sources, as Bacteroides phages serve as indicators of human sewage. The broth facilitates the recovery and quantification of phages through host enrichment techniques, making it valuable in public health studies, viral ecology, and wastewater treatment assessments. Its formulation enhances phage stability and host bacterial susceptibility, improving detection sensitivity in laboratory assays.
