Deoxycholate Lactose Agar Culture Media

Recovery of coliforms in milk and water.

Deoxycholate Lactose Agar was formulated by Leifson for the detection of coliforms in water, dairy products and other food materials. MyBioSource recommends Violet Red Bile Agar as the medium of choice for isolating coliforms from food products. Growth of coliforms which ferment lactose produce red colonies surrounded by a zone of red precipitate. The fermentation of lactose produces acid products which lowers the pH of the medium and the neutral red dye in the medium turns bright red. Sodium citrate and sodium deoxycholate are added to inhibit the growth of Gram positive bacteria.

Small volumes of Deoxycholate Lactose Agar culture media vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
