It seems to me that diluted solutions of Photo-Flo are vulnerable to mold.
I don't think either Triton-X or E/P Glycol will support life on their own.
But I have had something with all the appearance of microbial growth in used
working strength PF200/distilled water. I think enough gelatin and
Gawd-knows-what floats off of the film to supply the needed 'essential trace
nutrients' [what my Father would call the day's ration of one's obligatory
"1-pound of dirt in a lifetime"].
I have never had anything grow in a stock of ~1:80 PF600 'pre-dilution' made
up with 71% isopropanol (not at all surprising).
