Abstract

Microalgae (including cyanobacteria) have recently gained interest as a potential food and feed source due to their high nutritional value. Some microalgae and cyanobacteria have been traditionally consumed worldwide. Under the European Union’s legislation, they are considered, with only few exceptions, as novel foods, and therefore in order to enter the EU market it is required primarily to be authorized after risk assessment to ensure that they do not display any risk to public health. This chapter gives an overview of the current legislative situation of microalgae as food in the European Union and discusses the potential health risks associated with the consumption of microalgae and cyanobacteria.

Abstract

Microalgae are photosynthetic aquatic microorganisms that fix CO2 and other inorganic elements into organic matter. In general terms, microalgae are considered as a very interesting source of biomass because of their great diversity on biochemical and physiological properties and their convenient agronomical characteristics, like high biomass yield, fast grow, year-round harvesting capability, independence from arable land or irrigation-quality water. However, there are some important bottlenecks on the large-scale cultivation of microalgae and specific challenges exist. Currently there is a vast research activity trying to address these bottlenecks. The most challenging and critical points are related to the low biomass concentration on the cultivation medium, high energy consumption and costs for fertilization, agitation, harvesting and drying of biomass. This chapter aims to give an introductory overview on microalgal biomass production highlighting the potentials and limitations of microalgal cultivation, biomass production, biomass processing and application.

6. Nutrient recycling for sustainable production of algal biofuels

Abstract

Microalgae are an interesting new generation feedstock for the production of biofuels. However, their production costs are currently much higher than fossil fuels, restricting their commercial production. Among the various production processes, the consumption of fertilizers (carbon, nitrogen, phosphorus, etc.) contributes significantly to the total production costs. Moreover, it is projected that the use of industrially manufactured fertilizers will outcome in an unsustainable process, also raising competition between biofuels and food-crops for nutrient availability. To improve the economics and the sustainability of microalgal biofuels, an approach for recycling of nutrients from waste streams should be established, in order to apply nutrients from waste/wastewater at low cost, and to avoid using industrially manufactured fertilizers. For this purpose, a closed-loop production scheme should be developed, in which a series of technologies will be employed in order to obtain the main products (biofuels and other biorefinery products) along with a stream rich in spent nutrients for their reuse for further microalgae cultivation and biomass production.

Abstract

Bioalcohols (mainly bioethanol) are considered as one of the most promising substitutes for fossil fuels. Several feedstocks have been evaluated as substrates for bioethanol production and among them, microalgae have particularly emerged during the past years. This is due to their rapid growth, lack of competition with crops, the integration of production with wastewater treatment, and the fact that carbohydrates can be accumulated by manipulating cultivation conditions. Carbohydrates occur in microalgae as reserve products and as part of the cell wall. They can be converted into fermentable sugars through hydrolysis. For this reason, this chapter is focused on the study of the carbohydrates in microalgae biomass and methods to improve their accumulation as well as diverse pretreatments to break the cell wall, their release as monomeric sugars, and a comparison of the fermentation processes.
