“…Higher conversion yield of 100% in these studies confirms the superiority of the direct supercritical method compare to conventional solvent extraction methods. Nan et al (2015) quantify the unreacted glycerides using the GC-FID analysis and used it for calculation of FAMEs conversion yield. Patil et al (2012) determine the FAMEs yield based on total lipid content.…”

“…Subsequently, the lipids are transformed into biodiesel by trans-esterification [25]. However, the most energy intensive operation is biomass dehydration [26], and for this reason, some authors have proposed methods for direct transformation of intracellular lipids to biodiesel through processing of wet biomass [27][28][29]. Another common issue related to microalgal biodiesel is the presence of free fatty acids.…”

Microalgae transform CO2 into a broad portfolio of biomolecules, and thus should be considered as a valuable biotechnological platform. Despite several research programs and global efforts to establish a sustainable microalgae-based industry, most applications have not transcended academic boundaries. This limitation raises from the high transformation costs when target products are biofuels or fertilizers. Microalgae biorefinery emerges as an alternative to improve economic competitiveness, as Under such a model scope, the process inputs come from industrial waste, while biomass exploitation prioritizes the highest value molecules followed by extraction of less valuable compounds. This review describes a wide range of microalgae exploitation schemes focused on new uses of its constituents, while discussing emerging technologies designed to improve production and efficiencies as well.Keywords: microalgae; biorefinery; biofuels; fertilizers; active biomolecules. Biorefinerías de microalgas: aplicaciones actuales y nuevas tecnologías en desarrolloResumen Las microalgas transforman el CO2 en un amplio portafolio de biomoléculas, por lo cual, son consideradas una valiosa plataforma biotecnológica. A pesar de múltiples programas de investigación y esfuerzos globales para establecer una industria sostenible basada en microalgas, la mayoría de las aplicaciones potenciales no han trascendido las fronteras académicas. Esta limitación se debe a los altos costos en la transformación del producto principalmente cuando se obtiene compuestos económicos como biocombustibles y fertilizantes. La biorefinería de microalgas surge como alternativa para incrementar la competitividad económica. En este modelo, los insumos del proceso provienen de residuos industriales, mientras que la explotación de la biomasa inicia con las moléculas de alto valor y finaliza con los compuestos menos valiosos. En esta revisión se describe un amplio abanico de esquemas de explotación de microalgas enfocado en nuevos usos de sus constituyentes. Además, se exploran las tecnologías emergentes destinadas a aprovechar esta biomasa de una manera más versátil y eficiente.

“…Some studies have already opted for ethanol [25][26][27], therefore in this study we focus on propanol, butanol and petanol. Propanol is normally produced from petrochemicals by oxo-synthesis which is currently the most costeffective technique.…”
