Magnetically enhanced inductively coupled plasmas (MEICPs) typically display mode jumps as power or the magnetic field is increased. Inductive (H-mode) to helicon (W-mode) transitions in research reactors having uniform axial magnetic fields are often accompanied by a change in the spatial model structure and rapid increase in plasma density. In industrial plasma sources, the magnetic field str...

An attempt was undertaken to determine indicators of energy consumption in bio-electro reactors (BERs) i.e., an aerobic rotating electrobiological disc contactor (REBDC) and anaerobic sequencing batch biofilm reactor (SBBR), during contaminant removal from soilless tomato cultivation wastewater having a specific composition, high nitrate phosphorus concentrations low COD. Because this specifici...

The formation of acetate by Acetobacterium woodii was studied systematically in batch-operated stirred-tank reactors at different hydrogen and carbon dioxide partial pressures in the gas phase. 48 parallel stirred-tank reactors on a millilitre-scale as well as stirred-tank reactors on a litre-scale were applied for the detailed reaction engineering analysis of hydrogenotrophic acetate formation...

Sugar binding proteins and binders of intermediate sugar metabolites derived from microbes are increasingly being used as reagents in new and expanding areas of biotechnology. The fixation of carbon dioxide at emission source has recently emerged as a technology with potentially significant implications for environmental biotechnology. Carbon dioxide is fixed onto a five carbon sugar D-ribulose...

BACKGROUND Biogas is a renewable energy carrier which is used for heat and power production or, in the form of purified methane, as a vehicle fuel. The formation of methane from organic materials is carried out by a mixed microbial community under anaerobic conditions. However, details about the microbes involved and their function are limited. In this study we compare the metagenomes of four p...

This work presents a brief introduction on the basics of fiber-optical sensors and an overview focused on the applications to measurements in multiphase reactors. The most commonly principle utilized is laser back scattering, which is also the foundation for almost all current probes used in multiphase reactors. The fiber-optical probe techniques in two-phase reactors are more developed than th...

Five aerobic enrichments efficient at degrading methyl tert-butyl ether (MTBE) under different substrate conditions were developed in well-mixed reactors containing a polyethlene porous pot for biomass retention. The five substrate conditions were as follows: MTBE alone; MTBE and diethyl ether (DEE); MTBE and diisopropyl ether (DIPE); MTBE and ethanol (EtOH); and MTBE with benzene, toluene, eth...
