    Who knows what is the composition of CPS agar and CPSP agar?

    I just know that they are different in quantity of starch, but who have more? or what other components have these agar?

    I'm not familiar with this agar, if it's casein, peptone, serine I don't know what it would have to do with starch I tried searching for it but couldn't find it. Is this name English or a different language?

    Edit: Could it be CP agar? Complex polysaccharide agar?

    Edit2: If you can't find anything I'll dig out a text book and see if I can find something >.>

    Can you tell us what they are used to culture, i.e. gram negs, etc. Are they selective, enriched or a general growth media ? I've worked in a micro lab for a number of years, and never came across this one..unless it is used to grow non-human pathogens.

    I'm thinking it could be casein, peptone, starch from her description but I have no idea how that would be useful, I think this might be a language barrier issue.

    CPS is Casein Peptone Starch agar.

    If this was the medium intended, obscure is right - it's never gotten broad usage. A casein starch medium is used to isolate Acinomycetes.
