WebPhytase has been used to increase the absorption of several divalent ions, amino acids, and proteins in the bodies and to decrease the excessive phosphorus release in the manure to prevent negative effects on the environment. To date, microbial phytase has been mostly produced in solid-state fermentations with insignificant production volumes. Web1 jan. 2024 · Acids quickly dissociate into positive and negative ions when dissolved in water or aqueous solution. HCl acid, for example, dissociates into H+ can Cl- ions. The charged particles in the solution (H+ ions) make it much easier to transmit a current through a medium.
