Descripción general

Buffered peptone water being suitable as first diluent is helpful since the same homogenate can be used for detection of other microorganisms. Pre-enrichment of the culture media is performed using buffered peptone water to increase target concentration and improve sensitivity. It is also useful for the non-selective pre-enrichment of media for bacteria, in particular pathogenic members of the Enterobacteriaceae (sub-lethal damaged), from food and other material.

Aplicación

Buffered peptone water may be used to homogenize poultry samples. It may also be used in microbial culture of Staphylococcus aureus and followed by GC-MS analysis to determine the chemical composition of galangal extraxt and HPLC analysis to isolate compounds of Indian gooseberry extract.

Nota de preparación

Dissolve 20 g in 1 litre distilled water. Sterilize by autoclaving at 121°C for 15 minutes.

Almacenamiento y estabilidad

  • Store prepared media below 8°C, protected from direct light.
  • Store dehydrated powder, in a dry place, in tightly sealed containers at 2-25°C.

Studies have been carried out in which growth patterns of a Salmonella sp. and competing micro-organisms, especially other Enterobacteriaceae, were followed during pre-enrichment in buffered peptone water (BPw) and subsequent selective enrichment in tetrathionate broth (TBB). Pre-enrichment cultures were inoculated
