The stabiliser that comes in C-41 presskits

Probably older technology - note the use of the term "stabilizer".
And just because you don't have problem with environmental bacteria .....

Fuji EU uses Miconazole in E6 final rinse. Commonly used antifungal.

The stabiliser that comes in C-41 presskits always leaves white residue spots on the film. I can wipe them off the non-emulsion side with some isopropanol, but it is tempting to give a quick dunk in a PhotoFlo solution after the stabiliser.
I've got many years worth of XP2 developed in B&W chemicals that has never seen stabiliser. No signs of fungus even on the oldest (kept in plastic sleeves).

XP2 developed in b/w chemistry gives a silver image. Silver is a heavy metal and highly toxic to microorganisms. No need for preservatives.
