Lignocellulose integration to 1G-ethanol process using filamentous fungi: fermentation prospects of edible strain of Neurospora intermedia

Table 5 Fermentation profile of N. intermedia in the presence of inhibitors. Mycelial growth in semi-synthetic potato dextrose media at pH 3.5 represents pellets and at pH 5.5 represents filamentous forms, at varying inhibitor concentrations as observed in wheat straw-hydrolysate at different cultivation conditions
