There is an increasing need for sustainable sources of omega-3 fatty acids; this challenge can be addressed through large-scale production eicosapentaenoic acid (EPA) using microalgae. Identification suitable strains key in successful process scale-up. However, it not certain whether conclusions from small-scale systems (i.e. flasks and well plates) translated to larger photobioreactors. To exa...

It has been suggested that the energy-efficient production of microalgae biomass can be more easily obtained in short light path photobioreactors operated at high concentration. On downside, however, concentrations also require an efficient gas exchange rate to avoid metabolic growth limitation or inhibition. A cascade photobioreactor featuring a thin liquid layer flowing down sloping, wavy-bot...

Microalgal biomass is a promising alternative and renewable substrate for bioenergy production. The main problem its commercial application to obtain keep high level of production by providing microalgae with appropriate conditions growth. aim this study was determine optimal culture such as temperature, photoperiod, pH. amount gravimetry, optical density spectrophotometry, productivity were an...

Photobioreactor design is a subject of great relevance for the attainment of a sustained development in modern technology, and has also considerable interest from the basic scientific and technologic point of view. The aim of the present review paper is presenting and comparing some of the recent attempts by the authors of modelling photosynthesis in reactors. A short inspection of the kinetic ...

Biofuel production from renewable sources is widely considered to be one of the most sustainable alternatives to petroleum sourced fuels and a viable means for environmental and economic sustainability. Microalgae are currently being promoted as an ideal third generation biofuel feedstock because of their rapid growth rate, CO2 fixation ability and high production capacity of lipids; they also ...

Microalgae are a promising source of biofuels and bioproducts, as they consume CO2 to grow, multiply quickly, and can be cultivated in wastewater and on marginal land. Development of low-cost and high-efficiency microalgal cultivation systems is important to the cost-competitiveness of algae. A floating horizontal photobioreactor (HBR) was developed that is inexpensive and scalable, as it is ma...

The synthesis of renewable bioproducts using photosynthetic microorganisms holds great promise. Sustainable industrial applications, however, are still scarce and the true limits of phototrophic production remain unknown. One of the limitations of further progress is our insufficient understanding of the quantitative changes in photoautotrophic metabolism that occur during growth in dynamic env...
