The monitoring of must fermentation in a bioreactor, which the main physico-chemical parameters are tightly controlled, can provide useful analytical information transferable to winemaking on larger scale. In this experiment, we followed growth Saccharomyces cerevisiae during bioreactor-assisted alcoholic Chasselas by means flow cytometry. We used fluorescent dyes and volumetric counting monito...

the oxidation of ferrous iron (fe2+) in solution using acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. the aim of this investigation was to increase the...

Adventitious root culture and the development of a bioreactor are methods to obtain biomass plant bioactive compounds in large quantities faster than conventional cultivation. These technologies provide an excellent opportunity produce from plants, especially Gynura procumbens. Previous reports mentioned small-scale could increase G. procumbens adventitious roots. Therefore, larger for is neces...

Acid mine drainage (AMD) still represents a huge environmental problem. Technical and scientific breakthroughs are needed to decrease damages, treatment cost, waste production associated with AMD. The feasibility of combining continuously fed anaerobic sulfate-reducing bioreactor downstream iron oxidation step was tested, at laboratory scale, two types real arsenic-rich AMD waters from the site...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

background: in this study, the pilot production of aerobic bioreactor tropical theileriosis vaccine was optimized with the aim of immunological assays for further mass production. methods: we have shown earlier the delayed type hypersensitivity (dth) assay could be used for evaluating the immunity and memory cells against specific theileria antigen in vaccinated animals. in addition, tnf-α is t...
