COMPARATIVE STUDIES ON RESPIRATION : IX. THE EFFECTS OF ANTAGONISTIC SALTS ON THE RESPIRATION OF XXXX .

@entity3282 @entity1219 @entity11150
1. In the presence of 0.05 per cent dextrose the respiration of @entity11150 is increased by @entity1219 in concentrations of 0.25 to 0.5M, and by 0.5M @entity3282 . 2. Stronger concentrations, as 2M @entity1219 and 1.25M CaCl(2), decrease the respiration. The decrease in the higher concentrations is probably an osmotic effect of these salts. 3. A mixture of 19 cc. of @entity1219 and 1 cc. of @entity3282 (both 0.5M) showed antagonism, in that the respiration was normal, although each salt alone caused an increase. 4. Spores of @entity11150 did not germinate on 0.5M @entity1219 (plus 0.05 per cent dextrose) while they did on 0.5M @entity3282 (plus 0.05 per cent dextrose) and on various mixtures of the two. This shows that a substance may have different effects on respiration from those which it has upon growth.
