Enzymy katabolizmu weglowodanow z Cysttidicola farionis [Cystidicolidae]

The content of glycogen, glucose and trehalose was measured in larvae and adults of Cystidicola farionis, the parasite isolated from the swim bladder of Osmerus eperlanus from Vistula Lagoon. Activity of glycogen phosphorylase, α-amylase, glucoamylase. maltase, trehalase. And trehalose phosphorylase were measured. The highest activity was recorded for α-amylase 10,07 ± 0,97 mu/mg and 7,47 ± 0,24 mu/mg, next maltase 1,34 ± 0,63 μmol /mg and 2,06 ± 1,65 μmol/mg respectively for larvae and adults. The activity of glucoamylase was nearly the same for adults and larvae (about 0,20 μmol/mg). The trehalase activity was higher at adults (0,49 ± 0,42 μmol/mg) than at larvae (0,18 ± 0,12 μmol/mg). The activity of glycogen phosphorylase was much higher at larvae (3,58 ± 1,49 μmol/mg) than at adults parasite (0,10 ± 0,02 μmol/mg). The trehalose phosphorylase was present in both stages of parasite, but its activity was low. The content of glycogen and glucose was two-limes higher in the adults' body than in larvae.
