We analyzed herbaceous biomasses that have high contents of structural polysaccharides, reserve polyfructans and soluble sugars that can be converted by micro-organisms to ethanol. The present study examined the composition of Perennial ryegrass (Lollium perenne), Hybrid ryegrass (L .hybridum) and Italian ryegrass (L. multiforum), investigated the influence of cultivar, development stage, harvest time in the day, and tedding on carbohydrate availability in the harvested biomass. This study also checked the suitability for a direct conversion...
