Oxytetracycline Glucose Yeast Extract Agar (500 gram)
LV002-02107
Productomschrijving
Oxoid Oxytetracycline Glucose Yeast Extract Agar is recommended for the selection and enumeration of yeasts and moulds from foodstuffs. The medium using oxytetracycline as the selective agent is based on the formulation developed by Mossel et al. who stated that the use of this antibiotic in a medium with a neutral pH gave increased counts of yeasts and moulds from a variety of foodstuffs compared with media which relied on a low pH to suppress bacterial growth. Physically stressed yeast cells give higher counts on media which depend upon broad-spectrum antibiotics rather than a low pH for selectivity. In earlier work Mossel found that Glucose Yeast Extract Agar was as favourable a basal medium as `Mycophil’ Agar later recommended by Sharf. Addition of the oxytetracycline was found to make the Glucose Yeast Extract Agar more selective than `Mycophil’ Agar by inhibiting the growth of lactobacilli, most of which grow at the acid pH of the latter medium.
