Improved calibration of a solid substrate fermentation model

Noise Model for Realistic Simulations of Solid Substrate Fermentation Reactors

Measurements in large scale SSF bioreactors are contaminated with various kinds of disturbances, such as high, medium and low frequency noise, outliers and missing values. These make the operation of many control systems for SSF bioreactors unreliable and ineffective. In addition, it is difficult, time consuming and expensive to assess new control strategies in real time experiments. Alternativ...

Fast and reliable calibration of solid substrate fermentation kinetic models using advanced non-linear programming techniques

Heat transfer simulation in solid substrate fermentation.

A mathematical model was developed and tested to simulate the generation and transfer of heat in solid substrate fermentation (SSF). The experimental studies were realized in a 1-L static bioreactor packed with cassava wet meal and inoculated with Aspergillus niger. A simplified pseudohomogeneous monodimensional dynamic model was used for the energy balance. Kinetic equations taking into accoun...

Solid-substrate fermentation of corn fiber by Phanerochaete chrysosporium and subsequent fermentation of hydrolysate into ethanol.

The goal of this study was to develop a fungal process for ethanol production from corn fiber. Laboratory-scale solid-substrate fermentation was performed using the white-rot fungus Phanerochaete chrysosporium in 1 L polypropylene bottles as reactors via incubation at 37 degrees C for up to 3 days. Extracellular enzymes produced in situ by P. chrysosporium degraded lignin and enhanced saccharif...

Production and characterization of an acid Protease from a local Aspergillus Sp. by Solid substrate fermentation

The study aimed at isolating a potential acid protease producing fungal strain from local soil source. The fungal strains were isolated from garden soil on the basis of clearance zone on casein-glycerol agar flooded by coomassie blue stain. Aspergillus sp. showing maximum clearance on casein agar plates (pH 5) was selected for further studies. Optimization of various factors influencing maximum...
