They are highly vulnerable to fungal and bacterial contamination, due to the aqueous nature of the medium, the possible presence of plant fragments and the low content of organic compounds (some of which may have bactericidal and/or bacteriostatic properties). Such contamination can have several consequences.

As micro-organisms grow, they can feed on organic compounds, degrading them ...
