| Abstract: | The heat output of and the effect of manganese (II) on Tetrahymena shanghaiensis S199 growth metabolism has been determined by means of a LKB-2277 BioActivity monitor. Different concentrations of manganese(II) ions have different effects on the growth of T. shanghaiensis. At low concentrations (0-40 microg/mL) culture growth is promoted, whereas high concentrations (60-800 microg/mL) slow growth. Furthermore, concentrations of 1200 microg/mL or greater stop the growth of this protozooa completely. |
