Oxygen mass transfer in fermentation of bacillus thuringiensis

Oxygen mass transfer in fermentation of bacillus thuringiensis

The purpose of this work was to obtain a correlation based on literature, depicting the relationships betwen the physical oxygen transfer rate (OTR) and microbial oxygen uptake rate (OUR) in order to determine the conditions (mass transfer coefficient, resulting on diferents combinations of aereations and agitations rates), under which growth will not be limited by oxygen. This correlation was adapted to culture with B. thuringiensis in order to estimate what biomass concentration are feasible for the physical limits set by operations conditions before microbial activity becomes limited by oxygen.

Buitrago, G. Bacillus thuringiensis oxygen limited growth oxygen transfer Bacillus thuringiensis crecimiento limitado por oxígeno transferencia de oxígeno The purpose of this work was to obtain a correlation based on literature, depicting the relationships betwen the physical oxygen transfer rate (OTR) and microbial oxygen uptake rate (OUR) in order to determine the conditions (mass transfer coefficient, resulting on diferents combinations of aereations and agitations rates), under which growth will not be limited by oxygen. This correlation was adapted to culture with B. thuringiensis in order to estimate what biomass concentration are feasible for the physical limits set by operations conditions before microbial activity becomes limited by oxygen. Este trabajo se realizó con el propósito de implementar un modelo teórico a partir de la relación entre la velocidad de transferencia de oxígeno (OTR) y la demanda bioquímica de oxígeno (OUR), para hallar diferentes condiciones de velocidad de agitación y aireación, que determinan los coeficientes de transferencia de oxígeno, bajo las cuales el crecimiento microbiano no se vea afectado por deficiencias en el suministro de oxígeno. Tal correlación se adaptó al cultivo con Bacillus thuringiensis de manera que permita estimar para una concentración de biomasa máxima deseada, cual es la velocidad de suministro de oxígeno requerida para que no se presenten limitaciones de oxígeno en el cultivo.
