Effect of Particle Size on
Consolidated Bioprocessing Performance
• Particle size is an important limiting factor in enzymatic hydrolysis as it increases surface area accessible to enzymes
• Decreased Particle size increased conversion rates • Although at particle size 0.5 mm CBP sugar conversions were close to those of SSCF’s, SSCF reached almost the same conversions in 5 days reaction, twice as fast as CBP. |

In this study, they compared the optimal conditions for CBP with C. phytofermentans to the same conditions using SSCF using S. cerevisiae. It is important to note that SSCF at this point in time can achieve the same conversion rates of glucose and xylose as CBP in much less time and at higher loading times. However, our study indicates that CBP with the micro organism has a large potential impact on reducing the price of ethanol in the future.
