    Yeast cell (Saccharomyces Cerevisiae) metabolism has an important role in many biotechnological processes, such as in the production of bioethanol. The aerobic metabolism of yeast uses glucose to produce carbon dioxide, ethanol and heat. The growth of yeast cells consists of different stages, depending on the energy source of the cells. Calorimetry allows the determination of the growth phase from the cell culture, thus allowing the control of the metabolic cycle. In this paper, a nanocalorimetric heat sensor based on MEMS technology is used for the monitoring of small yeast cell populations, and an improved microsystem for cell measurements is proposed.
