Abstract
Investigations were made on the relation between the thiamine content of the medium and the yield of bakers' yeast under and aerobic condition. It was found that the yield of yeast was decreased by the addition of thiamine to the synthetic medium. The removal of thiamine from molasses medium by the adsorption using the acid clay was effective for increasing the yeast crop, but the destruction of thiamine by sodium sulfite was ineffective The addition of KCN was also effective for the elevation of yeast crop.
