Hypothesis
Can co-hydrolysis improve sugar yields from pretreated biomass compared to conventional methods?
Conclusion
Co-hydrolysis is a viable method for improving sugar yields from pretreated biomass, especially at lower solid concentrations.
Supporting Evidence
- Co-hydrolysis achieved good yields of glucose and xylose for poplar slurries at solid concentrations up to 2%.
- High enzyme loadings were necessary to achieve yields from co-hydrolysis similar to those from conventional methods.
- The influence of pretreatment severity on enzymatic hydrolysis was discernible even with co-hydrolysis.
Takeaway
This study shows that mixing everything together instead of separating it can help get more sugar from plants when making biofuels.
Methodology
The study used a high-throughput screening method to perform co-hydrolysis on pretreated biomass slurries without separating solids and liquids.
Limitations
The study primarily focused on specific pretreatment methods and may not generalize to all biomass types.
