The influence of humic acids on phytase activity isolated from wheat seeds

  • F. Pospíšil
  • Marie Hrubcová


Humic acids can inhibit the activity of wheat phytase in model experiments, because they are able to form complexes with hexainositol phosphates and have considerable adsorption properties. Decarboxylated humic acids do not show any inhibitory effects.

Vliv huminových kyselin na aktivitu fytázy isolovanou z obilek pšenice


Huminové kyseliny inhibují v modelových pokusech aktivitu pšeničné fytázy, vzhledem k tomu, že jsou schopné tvořit komplexy s hexainositolfosfáty a mají význačné adsorpční vlastnosti. Dekarboxylované huminové kyseliny nemají inhibiční účinky.
