Technology, which allows to make biofuels from algae more efficient

23 october 2013

Photosynthetic organisms, especially microalgae, occupy an important place in research aimed at finding new renewable fuels and raw materials for chemicals. Speed and efficiency with which grow microalgae, today is the limiting factor for their use as a competitive commercially available product. Thus, optimization of their production is obvious priority.

Ruston Colin (Colin Raston) from Flinders University in collaboration with colleagues from the University of Western Australia has developed a new way to increase the speed and efficiency of education accumulation photopigments, namely chlorophyll in algae.

Researchers algae Chlorella vulgaris cultured in flasks, which were surrounded by a solution containing gold and silver nanoparticles. Changes in the composition and size of nanoparticles contributes to changing the wavelength of light transmitted to the algae.

Although light and is important for the process of photosynthesis, the excess intensity of light may damage the algae and have a negative effect on photosynthesis. The method restricts the access to Ruston algae harmful wavelengths and at the same time, this method allows use of the backscattering of wavelengths, thus increasing the formation of the photochromic substance.

More Chlorophyll means may be absorbed more light and it can be used for the formation of biomass. Since nanoparticles are not in contact with the seaweed, the problems associated with impurities, does not arise.

Janet Scott (Janet Scott), an expert in the field of technology for "green chemistry" from the University of Bath in the UK, says that this method is an excellent example of an unconventional approach to business. Scott adds that although the method is not yet ready for commercial application, its concept is excellent and indicates interesting possibilities for further work on the application and theoretical study of the observed phenomenon.

Opinion divides Evan Scott Beach (Evan Beach) from Yale University in the United States. He also commented that the technology to transform algae into energy will be possible only on the basis kontseptsiibiopererabotki at which the fuel is produced along with more valuable products.


Currently the team has aimed at Ruston testing his method on other organisms capable of photosynthesis.
