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...

aerobic digestion was useful for mixed sludge of west ahwaz sewage treatment plant. results showed that after 12 days 38% of tvs reduced. this meets the environmental standards. after 19 days detention time in the bioreactor, cod, vss, tvs, tss, ts, were 40 ,56, 54.5 ,50.4 ,44.7 percent respectively. kd coefficient was,0.173day-1. aim of this bench scale study is determination of aerobic digest...

The paper investigates the static and dynamic behavior of a continuous flow bioreactor for the aerobic biodegradation of municipal and industrial waste. The unstructured kinetic model for the bioreactor accounts for oxygen limitation in the bioreactor model while the growth rate is described by the biomass-dependent Contois model. This kinetic model is known to explain the aerobic biodegradatio...

Water is a prime resource for any community, whether it is for household cleaning, sanitation, economic use or recreational purposes. In this paper a biological wastewater treatment process was studied, a membrane bioreactor under aerobic conditions was constructed. Different simulations were tried and several factors and parameters were emphasized. First, the membrane bioreactor was tested in ...

Anaerobic–aerobic systems have been remarkably employed in industrial and municipal wastewater treatment for many years. While previously most treatment of wastewaters have been carried out in conventional anaerobic–aerobic treatment plants, in recent years, high rate anaerobic–aerobic bioreactors have been increasingly employed for wastewaters with high chemical oxygen demand (COD). This paper...

the aerobic granular systems represent a good alternative to substitute the conventional activatedsludge process in the treatment of industrial effluents due to the lower surface requirements. in this work the effluent from a seafood industry, characterized by a high variability and the presence of residual amounts of coagulant and flocculant reagents, was used to study the development of aerob...

BACKGROUND Dissolved oxygen tension (DOT) is hardly constant and homogenously distributed in a bioreactor, which can have a negative impact in the metabolism and product synthesis. However, the effects of DOT on plasmid DNA (pDNA) production and quality have not been thoroughly investigated. In the present study, the effects of aerobic (DOT ≥30% air sat.), microaerobic (constant DOT = 3% air sa...

This study investigated the advantages of using low-cost polyaniline-fabricated stainless steel fiber felt anode-based microbial fuel cells (PANI-SSFF-MFCs) for azo dye acid blue 29 (AB29) containing wastewater treatment integrated with an aerobic bioreactor. The findings electrochemical impedance spectroscopy (EIS) and polarization studies showed that PANI–SSFF anode considerably decreased MFC...
