W. Borzani et al., A simple method to control the moisture content of the fermenting medium during laboratory-scale solid-state fermentation experiments, BRAZ J CH E, 16(1), 1999, pp. 101-102
When the moisture content of the fermenting medium significantly decreases
during laboratory-scale solid-state fermentation tests, the quantity of wat
er to be periodically added to the medium in order to control its moisture
content may be evaluated from the water evaporation rate of the non-inocula
ted medium.
