Copper 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...

Metabolism of glycine in carrot culture cells

"C n.m.r. spectroscopy has been applied to the investigation of glycine metabolism in tobacco cell cultures (Ashworth & Mettler, 1984) and tobacco protoplasts (Neeman c t ul., 1985). These investigations demonstrated that after prolonged incubation of cells with [2-"C]glycine, the C-2 of glycine was incorporated, in equal proportions. in both the C-2 and C-3 positions of serine; serine was the ...

Predictive modeling of biomass production by Chlorella vulgaris in a draft-tube airlift photobioreactor

The objective of this study was to investigate the growth rate of Chlorella vulgaris for CO2 biofixation and biomass production. Six mathematical growth models (Logistic, Gompertz, modified Gompertz, Baranyi, Morgan and Richards) were used to evaluate the biomass productivity in continuous processes and to predict the following parameters of cell growth: lag phase duration (λ), maximum specific...

An Experimental Study of Nanofluids Operated Shell and Tube Heat Exchanger with Air Bubble Injection

Shell and Tube heat exchangers are the heat exchangers that are most widely used in industries and for other commercial purposes. There are many techniques that have been utilized to enhance the heat transfer performance of the shell and tube heat exchangers. Air bubble injection is one of the promising and inexpensive techniques that can create turbulence in the fluids resulting in to enhancem...
