Abstract

The water activity (aw) of substrates has been related to the mycelial growth and the sporogenesis of two molds. In the absence of other limiting factors, optimal aw values were determined for growth and sporogenesis as 0.99 and 0.98, respectively, for Trichoderma viride TS and 0.97 and 0.96 for Penicillium roqueforti. In all cases, the accuracy of the optimal value would justify the regulation of this parameter. A model was proposed which establishes a relationship between the mycelial growth and the water activity value of the substrate.
