the maltose-fermenting strains will change the Bromcresol purple indicator into yellow

Carbenicillin is a beta-lactam type inhibitor of bacterial cell wall synthesis

The resulting steriometric change of the molecular structure of the antibiotic prevents it from binding at its ribosome binding site

Yeast Nitrogen Base Size:250g 2 at 25°C Suspend 70Yeast Nitrogen Base is based upon the formulation of Yeast Agar except that Ammonium Sulfate is the sole nitrogen source and that addition of carbon source is required. The medium may be used to test carbon assimilation in the presence of a carbon source like glucose, galactose or raffinose. Suspend 6. 9 gram powdered medium in 1 litre distilled water Store dry at room temperature
