The carbohydrate composition and the specific activity of the trehalase of cyclic partially synchronised yeast populations have been investigated. Under glucose limitation and appropriate cultural conditions synchronous growth in a chemostat was achieved. The cells accumulated the reserve carbohydrates during the single cell phase between two buddings. The rapid degradation of part of these reserves began shortly before the swelling of the bud. The importance of the mobilisation of endogenous reserves for the development of the cell is discussed.
The specific activity of the trehalase changed during the budding cycle. The result gives rise to the assumption that the synthesis of this enzyme is linked to the growth cycle.
