1) Various redox and endogenous pigments were used for the growth experiments, and little effects were observed in the growth rate.The effect of Fe^<2+> on the growth rate was observed to some wrong hypenation degree.2) The trace matal solution, which was modified by Vishniac's solution, little effected either the rate of growth or the sulfate formation.3) In a previous paper, it was reported that ammonium nitrate partially inhibited the growth, but it was not clear whether or not nitrate ion was utilized as a nitrogen source by the organism.In this research the authors have studies further the inhibitory effect of nitrate on growth and on the utilizazation of nitrate ion as a nitrogen source, and as terminal respiratory electron acceptor by the organism. About 60 per cent inhibition of normal growth was observed, but sulfate formation was only slightly inhibited by the sodium nitrate present. The nitrate ion as both a nitrogen source and a terminal respiratory electron acceptor was not able to be utilized. From these results, ammonium ion was an convenient source of nitrogen.A decrease in the economy of utililzation of energy was observed in the cases where there was a presence of nitrate.4) By determing the sulfate formed and oxygen gas consumed in the flask, the oxygen was almost completely transformed into sulfuric acid ; and this would lead us to conclude that the sulfur was oxidized according to the following reaction. S^0+3O+H_2O→SO_4^<2->+2H^+ As well, the free energy efficiencey of growth was studied under various conditions.
