Biocalorimetry can aid in the monitoring of solid-state fermentation (SSF) of lignocelluloses and enables to determine fungal growth rates and stages during growth on e. g. wheat straw. It further allows to determine species-specific fungal heat yield coefficients ( Y Q/X ), which indicate the degree of resource investment into fungal biomass versus other functional attributes. Y Q/X values seem suitable to link fungal potenti...
