YM-11 Agar is used for the selective enumeration of yeasts and molds using the ISO-GRID® and/or NEO-GRID® Membrane Filtration System. YM-11 Agar is not intended for use in the diagnosis of disease or other conditions in humans.
YM-11 Agar was formulated to stimulate rapid growth and colonial development of a wide range of fungi. Peptone sources were selected to maximize growth is this medium. YM-11 Agar is buffered at a neutral pH, and selective agents were included to inhibit bacteria growth.
YM-11 Agar is recommended for the rapid enumeration of yeasts and molds in all foods using the ISO-GRID and/or NEO-GRID Membrane Filtration System method.
