Now, a liquid culture jar, if it were to become contaminated, it would be rather evident, correct? This has been sitting on a darkish shelf in my coolish, non basementy- basement, for about 9 months. I used it successfully about 7 months ago.
What's throwing me off, is the brownish liquid. Before I stirred it recently, there was a pristine white layer over 1/4" thick floating on the surface.
The brown liquid, it's brown. The non pure white appearance has gotten into my head, that this jar is contaminated.
I don't need it, but man it would sure help if I could use this.
If I try it on say, a grain hat, I'd know fairly quickly that I had a problem correct? Yellow, green, black hues in the grain ect....
Let's hear some stories about how long a liquid culture had lasted.
