Method and apparatus for the determination of biomass in a suspension, such as a culture, in `real` time and a fermentation process using the method. In the method the electrical capacitance of the suspension is measured and from the measurement the volume fraction of the suspension enclosed by the cytoplasmic membranes of the cells (biovolume) is determined.
