Calculation of pressure growth during fermentation in a closed container.

The pressure measurement in the fermentation container can be used for the determination of the yeast activity or substrate fermentability. Pressure fermentation in sealed container also allows eliminating the influence of moisture, ethanol and CO2 escape during fermentation, which simplifies the ca...
