Mixing Estimation of a Laboratory-Scale External-loop Air-lift Bioreactor for Fungal Culture Using pH Tracer Method
Mixing has been one of the important parameters in characterizing and designing external air-lift bioreactors for the biological processes that require intensive mixing for mass transfer. In this study, pH tracer method was employed to characterize the mixing quality of a three-phase laboratory-scale external-loop air-lift bioreactor (EALR) used for cultivation of a pelletized filamentous funga...
متن کاملCopper Recovery from Chalcopyrite Concentrate by an Indigenous Acidithiobacillus ferrooxidans in an Air-Lift Bioreactor
In this study, effects of solid concentration, temperature, and initial Fe2+ concentration on bioleaching of sulfide mineral (chalcopyrite) obtained from Sarcheshmeh Copper Mine in the region of Kerman located in the south of Iran were investigated. A mesophilic iron oxidizing bacterium, Acidithiobacillus ferrooxidans has been isolated from a typical chalcopyrite copper concentra...
متن کاملDevelopment of a Pilot Plant Solar Liquid Desiccant Air Conditioner for the Northern Region of Iran
In a 10-ton capacity pilot plant solar liquid desiccant air conditioner (LDAC) developed, dehumidification of the outside air is achieved through a honeycomb packed-bed heat and mass exchanger, using lithium chloride solution as the desiccant. The dry air obtained from the dehumidification process is evaporative cooled inside a cooling pad and directed into the conditioned space. The dilute sol...
متن کاملLaccase activity from the fungus Trametes hirsuta using an air-lift bioreactor.
AIM To produce high laccase activities from the white-rot fungus Trametes hirsuta in an in-house air-lift bioreactor (ALB). METHODS AND RESULTS Trametes hirsuta was grown in a 6-l ALB. A fed-batch strategy with glycerol as an addition resulted in maximum laccase activity of 19,400 U l(-1), which was the highest reported from the fungus. CONCLUSION The ALB configuration with additional glyce...
متن کاملTo Study Yeast Growth Kinetics in a Specially Designed External Loop Airlift Bioreactor
Two types of airlift fermenters, conventional (UT-ALF) and modified (CDT-ALF) were investigated to evaluate their performance with respect to baker’s yeast growth. The riser tube of conventional external loop airlift fermenter is replaced by a converging-diverging tube. The new reactor is called modified airlift reactor. The results were compared for the two types of airlift fermenter (UT-ALF a...
