LITERATURE
Al3+
-
best as chloride at lower concentrations around 0.1 mM, inhibitory at higher concentrations
CaCl2
-
the ability of cold-water-extractable, heat-stable polymers (CHPs) to solubilize XTHs from Arabidopsis cell walls is mimicked by NaCl and CaCl2. The effect plateaues above about 30 mM CaCl2, while the CHP effect does not plateau even at the highest concentration tested (1.8 mg/ml). The relative effect of CHP is greatest (34fold promotion) in the absence of CaCl2, but strong CHP effects (4.6 to 9.1fold promotion) and much higher absolute XET activities are still detected in the presence of 15 mM CaCl2, indicating synergy between CHP and the inorganic salt
