Proteose Peptone Medium

I've got a problem with my medium for Neisseria gonorrhoeae, Proteose
Peptone. After autoclaving, there's some (a lot!) precipitation. The
clots have a rather waxy appearance, and do hardly dissolve even after
heating in the microwave.

Did anybody else ever encounter this problem? Could it be the starch?

I felt a bit unhappy "feeding" this to the bacteria...

Thanks a lot,
