Sry… soyabean Hiveg media.

Ya soyabean but not agar

we use soyabean casein digest medium in mediafill simulation study in aseptic area. in these we use 3% concentration of media.

so my question was why we use 3% concentration of soyabean casein digest medium? is their any guidelines or any recommendation by regulatory???

If we take more than 3% media ,it will be more viscous and there will be chance of chocking of filter during filtration and after media fill ,cleaning of equipment will be difficult.
If we take less than 3% concentration it will be not suitable media for microbial growth so 3% media solution is optimum concentration.
Refer USFDA guideline
