A mathematical model has been analyzed for in-situ bioremediation with the purpose of remediating organic contaminated soil. Oxygen rich water when passed through the porous media of soil activates the aerobic microorganisms, leading to the biodegradation of the organic content. The model equations comprise three convection-dispersion partial differential solution of these equations has been co...
Dissolved oxygen (DO) is an important factor for adenosine fermentation. Our previous experiments have shown that low oxygen supply in the growth period was optimal for high adenosine yield. Herein, to better understand the link between oxygen supply and adenosine productivity in B. subtilis (ATCC21616), we sought to systematically explore the effect of DO on genetic regulation and metabolism t...
Living tissues require a sufficient supply of oxygen for survival. An insufficient supply of oxygen may result from impairments of the respiration or oxygen transport systems, such as lung disease, heart disease, and anemia. Supplemental oxygen therapy increases the oxygen content in the lungs and blood oxygen saturation. The control of the oxygen flow is typically adjusted manually. This manua...
Twenty-four Hansenula polymorpha transformants were passaged and stabilised in glucose medium and screened in glycerol medium for recombinant phytase in shaken test tubes. The cultivations were performed under either limited or non-limited oxygen supply. Maximum oxygen transfer capacities of test tubes were assessed by sulfite oxidation. Oxygen-limited glucose cultures resulted in a partially a...
Tissue engineering is an attractive approach to heal bony defects. However, three-dimensional cell-scaffold constructs display uneven oxygen supply resulting in inhomogeneous tissue quality. We assessed different strategies to improve oxygen supply in vitro. Scaffolds with differing inner surface were seeded with preosteoblastic cells and cultivated either statically or in perfusion bioreactors...
