PALCAM Agar Base

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: Enzymatic digest provides essential carbon and nitrogen sources for growth. Yeast extract and corn starch supply carbon and nitrogen sources, vitamins and growth factors. Sodium chloride maintains osmotic balance, and glucose acts as a carbon source. Listeria hydrolyzes aesculin, which reacts with iron ions to form black 6,7-dihydroxycoumarin. Mannitol is a fermentable sugar and phenol red serves as a pH indicator. Lithium chloride and other antibiotics inhibit Gram-negative bacteria and most Gram-positive bacteria. Agar functions as the gelling agent of the medium.
