13. Carbohidratos y proteínas en microalgas: potenciales alimentos funcionales
Abstract Microalgae are organisms distributed throughout the planet, with hundreds of thousands of species since they have records. Its components with potential beneficial properties in nutrition and health have aroused scientific, industrial and commercial interest. In recent decades, several products have been developed, including functional foods and nut

15. CARBON DIOXIDE BIOFIXATION BY Chlorella sp. IN A BUBBLE COLUMN REACTOR AT DIFFERENT FLOW RATES AND CO2 CONCENTRATIONS
Abstract CO2 biofixation of the microalgae Chlorella sp. for different CO2 concentrations and gas flow rates in a bubble column reactor has been investigated in this study. Microalgae were cultivated under different CO2 concentrations (at 1.75% and 9.45% v/v) and gas flow rates (at 30, 50 and 70 ml/min). The maximum specific growth rate of Chlorella sp. was

16. Bioethanol from Microalgal Biomass: A Promising Approach in Biorefinery
Abstract The development of new technologies which increase the production of biofuel without directly compete with food production is required. Microalgal biomass has recently been in the highlight. The role of this biomass is here discussed within the concept of biorefinery and industrial sustainability of bioethanol production. The process of cultivation

18. INDUSTRIAL PLANT FOR PRODUCTION OF Spirulina sp. LEB 18
ABSTRACT Biorefineries based on microalgae produce biofuels and co-products with added value. Microalgae mainly require water, carbon dioxide and sunlight for growth. The bioproducts of the cultivation of these microorganisms can be fully used in a microalgae photobiorefinery. The objective of this work was to study the behavior of physico-chemical variables

19. Drying of microalga Scenedesmus obliquus BR003 in a gas dryer at low temperatures
ABSTRACT: Development of efficient and specific equipment to dry microalgae is essential for commercial use of these microorganisms that show high growth rates and biotechnological potential. Drying costs of microalgae biomass are still high and they should be reduced for the production of compounds with low added value. Therefore, we evaluated the drying p

21. Microalgae: Cultivation Aspects and Bioactive Compounds
Abstract Microalgae are aquatic unicellular microorganisms that can be found both in freshwater and marine systems; are capable of photosynthesis; and can grow as individual cells or associated in chains or small colonies. Microalgae cultivation has gained large momentum among researchers in the past decades due to their ability to produce value metabolites,

22. Consortium of Microalgae for Tannery Effluent Treatment
Abstract Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather)
