The growth of microorganisms inhibited by trialkyltin chloride (TAT) appreciably re-covered on the addition of potassium dihydrogen phosphate, and uptake of TAT by microbial cells was intensely inhibited by the same reagent. When TAT was mixed with potassium di-hydrogen phosphate or sodium pyrophosphate, a white sediment was found in the reaction mix-ture. This reaction proceeded most intensely in the range of pH 6.0_??_7.0. According to infrared analysis, this reaction product was shown to be a new compound which evidently dif-fers from the original ones. Elemental analysis of it showed that triethyltin chloride and potas-sium dihydrogen phosphate reacted in a molar ratio of 3 to 1. The interaction of TAT with phospholipids was also examined by silica gel thin layer chromatography, the results showing new reaction products having different Rf values from the original ones.
