Dear All,

I work in a product testing company. Recently we received a complaint
sample of electrolyte solution product (pH around 7) showing white mass as
contaminant. It is assumed to be a fungal contaminant. We did the
necessary TYMC using SDA, SCA, PDA plate, even removed the cottony mass and
placed it on the agar plate. However even on incubating for more than 7
days we did not observe any growth.

We assume that since the fungal mass was in high salt solution for a long
time maybe the fungal growth was stressed and so failed to grow in the
recommended media. Can anyone suggest how to overcome this? We need to grow
the fungus to identify it. Is there any media that will help us to recover
stressed fungus so that it can grow  in the recommended media. Kindly guide
us.

Thanking you in anticipation,

Regards,

Megha Goyal
