English name: Selenite Cystine Enrichment Broth (SC)
Specification: Powder, 250 g/bottle (common specification)
Product use: For selective enrichment culture of .
Product introduction: Selenite cystine enrichment broth, inhibiting Escherichia coli and other contaminants and promoting proliferation.
Composition: Peptone, lactose, disodium phosphate, sodium hydrogen selenite, L-cystine, pH approximately 7.0 ± 0.2 (25 °C).
Test principle: Selenite inhibits enterobacteria such as Escherichia coli; cystine promotes growth, achieving selective enrichment.
Usage: Weigh out an appropriate amount of this product, dissolve by heating to boiling (do not autoclave), cool to approximately 45 °C and dispense; inoculate with the sample and incubate at 36 ± 1 °C for 12–18 h, then subculture onto selective plates.
Microbial sensitivity test: Control strains: murium ATCC 14028, ATCC 19430 show good growth; Escherichia coli ATCC 25922 is inhibited.
