The model euryhaline cyanobacterium Synechococcus sp. PCC 7002 has potential as a platform for biotechnological applications because of its genetic amenability and fast growth rates. purpose this work was to measure the outdoor productivity metrics 7002, which we tested by cultivation in 110 L flat-panel photobioreactors 1025 open raceway ponds at Algae Testbed Public Private Partnership (ATP3)...
As the only fuel that is not chemically bound to carbon, hydrogen has gained interest as an energy carrier to face the current environmental issues of greenhouse gas emissions and to substitute the depleting non-renewable reserves. In the last years, there has been a significant increase in the number of publications about the bacterium Thermotoga neapolitana that is responsible for production ...
Macrophomina phaseolina was cultivated in complex and simple media for the production of extracellular lipolytic enzymes. Culture supernatants were batch foam fractionated for the recovery of these enzymes, and column design and operation included the use of P 2 frit (porosity 40 to 100 μ m), air as sparging gas at variable flow rates, and Triton X-100 added at the beginning or gradually in al...
AIR MIGRATION AND CHANGE OF CONTAMINANT CONCENTRATION IN GROUNDWATER INDUCED BY IN SITU AIR SPARGING
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
