Dynamic culture of human liver equivalents inside a micro-bioreactor for long-term substance testing
Background Current in vitro and animal tests for drug development are failing to emulate the organ complexity of the human body and, therefore, to accurately predict drug toxicity. In this study, we present a self-contained, bioreactor based human in vitro tissue culture test system aiming to support predictive substance testing at relevant throughput. We designed a microcirculation system inte...
Growing hairy roots in bioreactors has proven challenging. Here we summarize the recent work using a novel bioreactor, the mist reactor, for the culture of hairy roots from many plant species. Compared to most liquid-phase bioreactors, this gasphase bioreactor offers a completely different environment for growing roots. Design, modeling, and some of the unique engineering aspects inherent to mi...
The mathematical model of the integrated process of mercury contaminated wastewater bioremediation in a fixed-bed industrial bioreactor is presented. An activated carbon packing in the bioreactor plays the role of an adsorbent for ionic mercury and at the same time of a carrier material for immobilization of mercury-reducing bacteria. The model includes three basic stages of the bioremediation ...
In this work the Computational Fluid Dynamics simulation of a stirred bioreactor purposely designed for the production of hydrogen from organic wastes fermentation is presented. The bioreactor is a vortex-ingesting, dual impeller, mechanically-agitated vessel equipped with a central draft tube. Due to the geometrical and physical complexity, the selected reactor offers a very challenging benchm...
Introduction & Objective: Biological treatment is a new established technology for the air pollutants. This technology can be an alternative for physical and chemical treatment methods. Among bioreators, the Bioactive Foamed Emulsion Reactor (BFER) is a new alternative that has not the problems of the conventional ones. In this reactor bed clogging in the conventional bioreactor was resolved ...
Development of new techniques for in vitro culture is necessary to optimize and reduce the production costs. The aim of this work was to introduce the bioreactor BIB (Bioreactor of Immersion by Bubbles) and compare it with conventional culture and bioreactor RITA (Recipient with Automatized Temporary Immersion) for In vitro growth of M. alternifolia plantlets. Plantlets with 1.0 cm height from ...
The removal of gaseous ammonia in a system consisting of a biotrickling filter, a denitrification reactor and a polishing bioreactor for the trickling liquid was investigated. The system allowed sustained treatment of ammonia while preventing biological inhibition by accumulating nitrate and nitrite and avoiding generation of contaminated water. All bioreactors were packed with cattle bone comp...
BACKGROUND Globally, the development of a cost-effective long-term renewable energy infrastructure is one of the most challenging problems faced by society today. Microalgae are rich in potential biofuel substrates such as lipids, including triacylglycerols (TAGs). Some of these algae also biosynthesize small molecule hydrocarbons. These hydrocarbons can often be used as liquid fuels, often wit...
