“…Recycling nitrogen, phosphorous and other nutrients is a strategy to address some of these challenges while addressing other ecological issues such as eutrophication. Algae are capable of utilizing nutrients (including, nitrogen and phosphorus) from wastewater and thus could play a key role in nutrient recovery from waste waters [42,51,[214][215][216][217][218][219][220][221]. Maximizing algae production and minimizing costs associated with harvesting are critical to cost-effective nutrient removal system development [222].…”

Due to significant lipid and carbohydrate production as well as other useful properties such as high production of useful biomolecular substrates (e.g., lipids) and the ability to grow using non-potable water sources, algae are being explored as a potential high-yield feedstock for biofuels production. In both natural and engineered systems, algae can be exposed to a variety of environmental conditions that affect growth rate and cellular composition. With respect to the latter, the amount of carbon fixed in lipids and carbohydrates (e.g., starch) is highly influenced by environmental factors and nutrient availability. Understanding synergistic interactions between multiple environmental variables and nutritional factors is required to develop sustainable high productivity bioalgae systems, which are essential for commercial biofuel production. This article reviews the effects of environmental factors (i.e., temperature, light and pH) and nutrient availability (e.g., carbon, nitrogen, phosphorus, potassium, and trace metals) as well as cross-interactions on the biochemical composition of algae with a special focus on carbon fixation and partitioning of carbon from a biofuels perspective.

“…The issue of secondary pollution is solved due to very efficient biomass reuse and nutrient recycling. Moreover, the versatility of microalgae is further exploited in the production of biofertilizers, feed for animals and fine chemicals [10,11]. However, the macromolecular composition (lipids, carbohydrates, proteins, nucleic acids) and pigments contents of microalgae biomass are influenced by growth conditions.…”

Growth comparison of microalgae in tubular photobioreactor and open pond for treating anaerobic digestion piggery effluent

et al. 2016

The overwhelming interest in the use of microalgae to handle associated nutrient surge from anaerobic digestion technologies for the treatment of wastewater, is driven by the need for efficient nutrient recovery, greenhouse gas mitigation, wastewater treatment and biomass reuse. Here, the feasibility of growth and ammonium nitrogen removal rate of semi-continuous mixed microalgae culture in paddle wheel-driven raceway pond and helical tubular closed photobioreactor (Biocoil) for treating sand-filtered, undiluted anaerobic digestion piggery effluent (ADPE) was compared under outdoor climatic conditions between June and September 2015 austral winter season. Two Biocoils, (airlift and submersible centrifugal pump driven) were tested. Despite several attempts in using airliftdriven Biocoil (e.g. modification of the sparger design), no net microalgae growth was observed due ) was 2.1 times higher than in raceway pond. While no significant differences were detected between the cultivation systems, the overall carbohydrate, lipid and protein contents of the consortium averaged 29.17 ± 3.22, 32.79 ± 3.26 and 23.29 ± 2.15% AFDW respectively, revealing its suitability as animal feed or potential biofuel feedstock. The consortium could be maintained in semi-continuous culture for more than three months without changes in the algal composition. Results indicated that microalgae consortium is suitable for simultaneous nutrient removal and biomass production from piggery effluent.

AGRADECIMIENTOSEs difícil expresar en estas cortas líneas todo el agradecimiento que siento hacia tantas personas que han estado a mi lado durante el desarrollo de este trabajo. Lo voy a intentar:En primer lugar quisiera agradecer a mis supervisores José y Aurora por darme la posibilidad de desarrollar mi trabajo, porque sin ellos y sin el grupo que ellos dirigen esta tesis simplemente no existiría. Gracias también a Joaquín por su indispensable ayuda en el tratamiento de los datos y el desarrollo de los modelos, por todos sus valiosos comentarios y por darme el ritmo que me ha ayudado a avanzar.Los comienzos no son fáciles, pero gente como Luis, Javier Eduardo o Brenda hicieron el mío mucho más agradable. Gracias por motivarme, por llevarme a por garrafas a la Albufera, por darme la mano en mis primeros pasos en el laboratorio, con el micro o con la programación y, en definitiva, por estar ahí y echarme una mano siempre que lo he necesitado.Un hueco ahora para el resto de compañeros de Burja. Gracias por todo lo que he aprendido de vosotros: a Juan por su calma, su ejemplo riguroso y metódico y por todas las charlas dentro y fuera del lab; a Rafa por sus trucos, sobretodo el del Foxit, sin él aún no habría terminado de escribir la Introducción; a Nacho por la ayuda en el laboratorio con los montajes y a Víctor por todas las ideas y materiales. Gracias a Javi Claros por ser un gran ejemplo a seguir y por las risas; a Emérita por escuchar con atención y comprensión y a Josep por su paciencia y buen humor en el diseño de la planta. Gracias a Alberto por hacer que todo funcione y a Nuria por ser un encanto. Gracias por supuesto también a Laura S, Laura C, Ana, Marta, Cecilia, Patri, Silvia, Mónica y Joana, con quienes he compartido tantos momentos en despachos, laboratorios e incluso una mudanza: el día a día pesa menos con vosotras.Quiero agradecer también a Ángel y Freddy, los "becarios NASA" que saben (casi) de todo y ayudan siempre. Gracias por aguantar mi cháchara y por todo el apoyo y guía que habéis supuesto para mí. Gracias a Dani por el buen rollo constante y por enseñarme a ii mover muy rápido el ratón y a Ruth y Alex por completar de manera inmejorable el despacho. Del montón de cosas que quiero agradecer a Tao me quedo con el "la-laaa la-laaa" limpiando el PBR…porque lo resume todo.Todo esto sin olvidarme de los demás en el poli: gracias a Antonio y Ramón por su buen humor, a Dani Aguado por su interés, a Inma por su calidez y a María y Vicky porque siempre me han escuchado, animado y ayudado al instante.También quiero agradecer a mis amigos porque, aunque a veces sin saber muy bien qué hago, siempre han mostrado su interés por "cómo van mis algas". A Aixa, Inma, Lore G, Lore S, Ana C, Mayte, Silvia, Amparo, Laura, David, Bea, Paz, Patri, Raquel, Ruth, Aldara, Davide, Bruno… y a los masterfrens Lenin, Anahí, Liz, Benni y Jota por la fantástica "vuelta al poli" que tuve, al principio de esta aventura, gracias a ellos.La familia se suele dejar para el final en los agradecimientos, pero en realidad es lo p...
