Baird-Parker 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: Tryptone, beef extract powder and yeast extract powder supply carbon and nitrogen sources, vitamins and growth factors. Sodium pyruvate and glycine stimulate the growth of staphylococci. Lithium chloride and potassium tellurite inhibit microorganisms other than staphylococci. Staphylococci producing lecithinase degrade egg yolk, forming clear zones around colonies, while lipase activity results in opaque precipitate rings. Coagulase-positive staphylococci can also reduce potassium tellurite to produce black colonies. Agar serves as the gelling agent for the medium.
