Abstract

ABSTRACT The use of current energy has generated many e vironmental problems that increase every day the interest of searchers in order to develop new technologies for clean resources using the renewable ener y. Seaweeds, with their rapid growth, have the potential to become industrial photochemical converters. These photosynthetic seaweeds, under determinated conditions are able to produce liquid fuels and clean renewable chemicals. Optically, investment and operating costs are the main constraints to optimize for the improvement of bioprocesses technics. From this perspective, various approaches are studied. In the present study, we present and describe the main parameters and limiting factors and we show that only the appro ch of sunlight is economically realistic. One of the main objectives in the field of seaweeds is to dilute the light to overcome the effects of photosaturation that have an impact on crops in the sun, and we also appear the importance of external parameters independent of nutrient environment on growth. Another approach was also discussed, which is an adaptation technique based on spectral luminescence in order to optimize the solar spect um the desired bioconversion requirements.
