✦ Synopsis


Transport of ferrous iron by phospholipids, from various Thiobacillus species and commercial sources, was studied as a liquid membrane permeability phenomenon using a modified apparatus of Schulman. It was observed that phosphatidyl serine enhanced the iron transport at a considerably higher level than phosphatidyl glycerol, phosphatidyl ethanolamine or phosphatidyl choline in that order. No difference was observed in the iron transporting ability of the phospholipids from thiobacilli and the standard phospholipids. Phosphatidyl serine was found to have more cation exchanging properties under the given conditions, than any of the other phospholipids tested.
