In the context of increasing trap age, we characterized microbial community composition using phospholipid fatty acid (PLFA) analysis and microscopy. Nutrient content in various fractions of the trap fluid was analyzed and the abundance of free-suspended bacteria estimated. The activities of extracellular phosphatase in the trap fluid were determined using fluorometry and the contribution of the microbial community to phosphatase production assessed by epifluorescence microscopy. Our findings support the hypothesis that mutualism is an important association in aquatic Utricularia traps and that the trap-associated microbial community may be of benefit to the rootless aquatic Utricularia species facing problems with P acquisition due to the loss of roots in their evolution.
