What is the difference between Bacto yeast extract & Difco yeast extract?

I e-mailed BD on 2012/03/01 and asked "What is the difference between Difco Yeast Extract and Bacto Yeast Extract? I only see Difco Yeast Extract UF in this: http://www.bd.com/ds/technicalCenter/misc/br_3_2547.pdf so it is hard to compare. I have an old bottle of Difco Yeast extract that is not UF and I wonder if it can be substituted for Bacto Yeast extract. It is also old (1999) -- does it go bad?"
