Various kinds of organic metal compounds have recently been synthesized. Some of them have preservative effects on textile fibers. Experiments were carried out on Finechem N-5, 10 % aqueous solution of an organic tin compound, to study its preservative effects on pulp and its antibacterial power against slime forming microorganisms. The following observations were made: 1. A total of 83 strains of bacteria and fungi were isolated from pulp slime. Of them all, 23 strains were found to be capable of forming slime. 2. This organic tin compound inhibited the multiplication of most of slime forming microorganisms at concentrations lower than 50 p.p.m. Inoculation with slime forming microorganisms of ground pulp, that had been treated with this chemical at concentrations higher than 10 p.p.m., did not cause any change until the fourth day following inoculation. 3. Fungi were generally more resistant to this chemical than bacteria. 4. It is concluded that, while organic tin compounds are slightly inferior to organic mercurial compounds in their antibacterial power against slime forming microorganisms and preservative effects on pulp, the former nonetheless have a number of advantages from economic and hygienic viewpoints, and, therefore, have some commercial value.
