An Alternative Route for Astaxanthin Biosynthesis in Green Algae

Hydrodynamic Cavitation: An Alternative Method for Algae Removal from Water Resources

Transformation of the green alga Haematococcus pluvialis with a phytoene desaturase for accelerated astaxanthin biosynthesis.

Astaxanthin is a high-value carotenoid which is used as a pigmentation source in fish aquaculture. Additionally, a beneficial role of astaxanthin as a food supplement for humans has been suggested. The unicellular alga Haematococcus pluvialis is a suitable biological source for astaxanthin production. In the context of the strong biotechnological relevance of H. pluvialis, we developed a geneti...

Field equations for gravity: An alternative route

We present an alternative derivation of the gravitational field equations starting from the Newton’s law, which intrinsically brings in observer dependence in the theory. Projecting the Riemann curvature tensor appropriately as fit for an observer, taking a cue from Poisson’s equation, the Einstein’s equations immediately follow. Our derivation naturally adapts to Lovelock gravity theories wher...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Respiration in blue-green algae.

The low rate of endogenous respiration exhibited by the blue-green algae Anacystis nidulans and Phormidium luridum was not increased by the addition of respiratory substrates. However, endogenous respiration was inhibited by low concentrations of cyanide and by high carbon monoxide tensions. In addition, the uncouplers dinitrophenol and carbonyl cyanide p-trifluoromethoxyphenylhydrazone both st...
