Enzymatic activities in traps of four aquatic species of the carnivorous genus Utricularia.

Original language description

Enzymatic activity of five hydrolases was measured fluorometrically in the fluid collected from traps of four aquatic Utricularia species and in culture water. In empty traps, the highest activity always exhibited phosphatases (6.1-29.8 micromol l-1 h-1)and &#946;-glucosidases (1.35-2.95 micromol l-1 h-1), while the activities of &#945;-glucosidases, &#946;-hexosaminidases, and aminopeptidases were usually lower by one or two orders of magnitude. Two days after prey addition, all enzymatic activities in the traps decreased conspicuously in U. foliosa and U. australis but markedly increased in U. vulgaris. Phosphatase activity in the empty traps was 2-18 times higher than that in the culture water at the same pH of 4.7, but activities of the other trapenzymes were usually higher in the water. Correlative analyses did not show any clear relationship between these activities. Trap comensals (Euglena) could partly be responsible for production of some trap enzymes. The traps can produce
