What is YGC agar culture medium?
Yeast Glucose Chloramphenicol Agar or YGC agar is a selective culture medium used to count yeasts and molds in milk and dairy products. The selectivity of this culture medium is due to the presence of chloramphenicol in its compounds, which prevents the growth of other microorganisms in the culture medium. YGC Agar culture medium is a nutrient medium and yeast extract is an essential nutrient. The traditional method of acidifying agar to count yeasts and molds in dairy products has now been replaced by antibiotic agar methods.

It also provides better control of bacteria and less interference when counting precipitated food particles.
