Hydrogen may be considered a potential fuel for the future since it is carbon-free and oxidized to water as a combustion product. Bioconversion of synthesis gas (syngas) to hydrogen was demonstrated in continuous stirred tank bioreactor (CSTBR) utilizing acetate as a carbon source. An anaerobic photosynthetic bacterium, Rhodospirillum rubrum catalyzed water-gas shift reaction which was applied ...
The potential bioconversion of synthesis gas (syngas) to fuels and chemicals by microbial cell has attracted considerable attention in past decade. The feasibility of enhancing syngas bioconversion to ethanol and acetate using Clostridium ljungdahlii in a continuous tank bioreactor (CSTBR), kinetics and mass transfer coefficient of carbon monoxide (CO) utilization were evaluated. Two different ...
AIMS To optimize peroxidase production by Streptomyces sp. strain BSII#1, up to 3 l culture volumes. METHODS AND RESULTS Peroxidase production by Streptomyces sp. strain BSII#1 was optimized in terms of production temperature and pH and the use of lignin-based model chemical inducers. The highest peroxidase activity (1·30 ± 0·04 U ml(-1) ) in 10 ml culture volume was achieved in a complex pro...
We have developed a chip-based cell culture system for the three-dimensional cultivation of cells. The chip is typically manufactured from non-biodegradable polymers, e.g., polycarbonate or polymethyl methacrylate by micro injection molding, micro hot embossing or micro thermo-forming. But, it can also be manufactured from bio-degradable polymers. Its overall dimensions are 0.7 1 x 20 x 20 x 0....
The development of energy-efficient solutions for large-scale fermenters demands a deep and comprehensive understanding hydrodynamic heat mass transfer processes. Despite wide variety research dedicated to measurements intensity in bubble flows, this subject faces new challenges due the topical innovative bioreactor designs. In order understand fluid dynamics gas–liquid medium, researchers need...
Five landfills were analyzed to provide a perspective of current practice and technical issues that differentiate bioreactor and recirculation landfills in North America from conventional landfills. The bioreactor and recirculation landfills were found to function in much the same manner as conventional landfills, with designs similar to established standards for waste containment facilities. L...
a solid – liquid – gas, multiphase reactor, called inverse fluidized bed bioreactor (ifbbr) was used in this study for the treatment of starch industry wastewater of high organic content and acidic nature. mixed culture obtained from the sludge, taken from starch industry effluent treatment plant, was used as microorganisms. experiments were carried out in an inverse fluidized bed bioreacto...
