Opis

Opis ogólny

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.

Zastosowanie

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.

Uwaga dotycząca przygotowania
