Mine drainage waters vary considerably in the range and concentration of heavy metals they contain. Besides iron, manganese is frequently present at elevated concentrations in waters draining both coal and metal mines. Passive treatment systems (aerobic wetlands and compost bioreactors) are designed to remove iron by biologically induced oxidation/precipitation. Manganese, however, is problemat...

Plants may serve as superior production systems for complex recombinant pharmaceuticals. Current strategies for improving plant-based systems include the development of large-scale production facilities as well as the optimisation of protein modifications. While post-translational modifications of plant proteins generally resemble those of mammalian proteins, certain plant-specific protein-link...

The use of plants as bioreactors for the large-scale production of recombinant proteins has emerged as an exciting area of research. The current shortages in protein therapeutics due to the capacity and economic bottlenecks faced with modern protein production platforms (microbial, yeast, mammalian) has driven considerable attention towards molecular pharming. Utilizing plants for the large-sca...

Single-use bioreactors are commonly used for seeding stainless steel bioreactors or for producing material. The profitability of these equipments has been well demonstrated on more that decade. But few data on its scalability have been published. In 2010-2011, Merck Serono Biodevelopment performed a study in order to evaluate the performance of several disposable bioreactors. As different techn...

The bacterial community structure of 10 different wastewater treatment systems and their influents has been investigated through pyrosequencing, yielding a total of 283486 reads. These bioreactors had different technological configurations: conventional activated sludge (CAS) systems and very highly loaded A-stage systems. A-stage processes are proposed as the first step in an energy producing ...

Application of plant expression systems in the production of recombinant proteins has several advantages, such as low maintenance cost, absence of human pathogens, and possession of complex post-translational glycosylation capabilities. Plants have been successfully used to produce recombinant cytokines, vaccines, antibodies, and other proteins, and rice (Oryza sativa) is a potential plant used...

The basic characteristic of batch bioreactors is their inability to inflow or outflow the substances during fermentation process. This follows in simple construction and maintenance, which significant advantage bioreactors. Unfortunately, this also results current industrial laboratory control production process duration. In some recent studies, it was shown that changing temperature could infl...

Introduction Single-Use Bioreactors are now commonly used for Process Development activities, as seeding bioreactors or to produce Drug Substances. The advantages of this equipment have been well demonstrated over the last years on batch/fed-batch processes. Continuous processes were widely applied in the past to increase the overall productivity of small bioreactors or for sensitive molecule p...

the gf677 (prunus amygdalus×prunus persica) is a peach rootstock tolerant to fe deficiency .therefore, mass propagation of gf677 rootstock is recommended by bioreactor. on the other hand, plant micro-propagation using bioreactors can decrease the cost of production and makes it an economical method. in this research, the possibility of using bioreactor and optimization of the tissue culture pro...
