This material, which was thought to be the oxidized form of a powerful oxidation-reduction system, was found to have baetericidal and fungicidal properties (Stuart and Harris, 1942), to inhibit fermentation of wheat mashes (Balls and Harris, 1944), and to be toxic to laboratory anim?is (Coulson et al., 1942). %P 31-60 %B Oxford Surveys of Plant Molecular and Cell Biology %V 6 %D 1989 %C UK %I Oxford University Press %L upm6055
