Abstract
A variety of antibiotics and other possible inhibitors were tested against C. pyrenoidosa in both long-term growth tests and in short-term tests of ability to assimilate carbon dioxide in the light. Under conditions of growth inhibition bacitracin, erythromycin, and oxytetracycline appeared to have some stimulatory effect on carbonate-fixation. Gliotoxin, thiolutin, poly-myxin B, and streptomycin inhibited the carbonate-fixation. For the latter 3 compounds, a study of cell extracts by chromatography-autoradiography provided some evidence that the carbonate-fixation inhibitions were consequences of other, more direct inhibitions.
