Description

Application

OGYE ChromoSelect Agar Base is a selective and differential medium which facilitates rapid isolation of yeasts and moulds from milk and milk products. Oxytetracycline makes the medium more selective by inhibiting the growth of Lactobacilli. A. niger appears as light blue colored colonies with black spores due to presence of chromogenic mixture, C. albicans shows green colored colonies and S. cerevisiae gives colorless colonies.

Notes préparatoires

Suspend 18.55 g in 500 ml distilled water. Boil to dissolve the medium completely. Sterilise by autoclaving at 121°C for 15 min. Cool to 50°C and aseptically add reconstituted contents of one vial of Oxytetra Selective Supplement (Cat. No. 51239). Mix well and pour into sterile petri plates.
