I was curious how the bacteria get into the plant if it is grown
in culture. I was told they are in the air and on the prey but I
feared that it takes a certain (maybe rare) type of bacteria for
the Heliamphora. I am more than happy if everything works fine
without intervention.

I only mentioned the reverse osmosis water to make sure I don't
use rain water (with another possible source for bacteria).

Yes, that was my intended question.

Exactly my train of thought as I often found references to papers
on special species of pitcher plant micro-organisms.
Thanks for all contributions!!!
