| Abstract: | Lignocellulosic biomass was pretreated with lime, and used for the production of VFA (volatile fatty acid) through batch anaerobic digestion. About 0.34 g VFA yield was obtained using 10 g/L reed, after 3 days of fermentation with lime treatment; however, a higher VFA yield (more than 0.5 g/g biomass) was achieved with a modified lime treatment. Overall, our study showed that that the modified lime treatment is better suited for VFA production. VFAs can be widely used in platforms for fuels and chemicals from biomass. |
