TOS Propionate Agar

( 221 )

TOS Propionate Agar (TPA) is a medium for the direct detection of viable Bifidobacteria. The method is applicable to milk products such as fermented and non-fermented milks, milk powders, infant formulae, and starter cultures where these microorganisms are present and viable, and in combination with other lactic acid bacteria.

In combination with MUP, it allows the direct detection of viable Bifidobacteria.

Cat No. EG-M-TPA-1-1K

Application

-Selective isolation and enumeration of Bifidobacteria
-Microbiological analysis of dairy products (milk, infant formula, fermented products)
-Quality control of probiotic and starter cultures
-Detection of viable Bifidobacteria in mixed cultures with lactic acid bacteria
-Enhanced identification of Bifidobacteria when used with MUP

Preparation

 Suspend 54.7 g of dehydrated medium in 950 ml of distilled water (use 1 liter for non-selective medium).   Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 115 °C for 15 minutes.
 For selective isolation of Bifidobacteria, add the contents of two 25 ml vials of Lithium Mupirocin Supplement.   Mix carefully to avoid air bubble formation and dispense as desired.

 Note: This medium is sensitive to heat; excessive heat treatment may adversely affect its properties.
