Violet Red Bile Glucose Agar (VRBGA)

1.Due to varying microwave power, if the medium is not fully melted within 3 minutes, crush it into pieces before heating on high power, or extend the heating time by 0.5 to 1 minute.
2.Check for contamination. Do not use if microbial growth is observed.
3.Pour plates under aseptic conditions to prevent microbial contamination.
4.Do not overheat in the microwave, as excessive heating will cause severe water loss and reduce the nutritional performance of the product.
5.This product is for single use only. Pour out all the medium in the bottle and avoid repeated melting and solidification.
6.This product is not intended for clinical diagnosis. Test Principle: Peptone and yeast extract serve as basic nutrients, supplying nitrogen sources, vitamins and other mineral elements required for bacterial growth. Glucose is a fermentable carbohydrate. Sodium chloride maintains osmotic balance. Neutral red acts as an indicator; acid produced from glucose fermentation changes its color, turning colonies red. Bile salts and crystal violet inhibit the growth of Gram-positive bacteria.
