A discretized model for enzymatic hydrolysis of cellulose in a fed-batch process

Techno-economic Implications of Fed-batch Enzymatic Hydrolysis

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Enhancing Enzymatic Hydrolysis of Cellulose by Ultrasonic Pretreatment

Slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). Susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. Maximum glucose yi...

Production of cellulase on mixtures of xylose and cellulose in a fed-batch process.

Cellulase production by the RUT-C30 mutant of the fungus Triclzoderma reesei on mixtures of xylose and cellulose was studied in a fed-batch system. An initial mixture of 30 g/L xylose and 20 g/L cellulose and an intermittent feeding rate of 5 g/L/day xylose and 15 g/L/day cellulose (total of 20 g/L/day) produced the highest titer of enzyme activity of 12.5 IFPU/mL, 57% higher than for a batch s...

Modelling of a Fed-Batch Fermentation Process

This report describes the building of a simulator for prediction of the dissolved oxygen concentration, the oxygen transfer rate and the concentration of carbon dioxide in a fermentation process. The steady state models were made using the linguistic equations method. The dynamic models were made using Simulink ® toolbox in the Matlab ® . At the beginning, some basics about fermentation and mic...
