Algal-based wastewater remediation systems (phycoremediation) include phycosphere bacterial communities that influence algal growth, pollutant remediation, and downstream applications of biomass as fertilizers or bio-stimulants. This study investigated the bacterial community dynamics in a novel phycoremediation system using a co-culture of the gre...
Microalgal biomass is widely studied for its possible application in food and human nutrition due to its multiple potential health benefits, and to address raising sustainability concerns. An interesting field whereby to further explore the application of microalgae is that of beer brewing, due to the capacity of some species to accumulate large am...
Tetraselmis chui is known to accumulate starch when subjected to stress. This phenomenon is widely studied for the purpose of industrial production and process development. Yet, knowledge about the metabolic pathways involved is still immature. Hence, in this study, transcription of 27 starch-related genes was monitored under nitrogen deprivation a...
Cell wall disrupted and dried Microchloropsis gaditana (Mg), Tetraselmis chui (Tc) and Chlorella vulgaris (Cv) microalgae biomasses, with or without ethanol pre-treatment, were added to wheat bread at a wheat flour substitution level of 12%, to enrich bread protein by 30%. Baking performance, protein quality and basic sensory properties were assess...
The use of microalgal starch has been studied in biorefinery frameworks to produce bioethanol or bioplastics, however, these products are currently not economically viable. Using starch-rich biomass as an ingredient in food applications is a novel way to create more value while expanding the product portfolio of the microalgal industry. Optimizatio...
In addition to the rapidly expanding field of using microalgae for food and feed, microalgae represent a tremendous potential for new bioactive compounds with health‐promoting effects. One field where new therapeutics is needed is cancer therapy. As cancer therapy often cause severe side effects and loose effect due to development of drug resistanc...
Both enzymatic or oxidative carotenoids cleavages can often occur in nature and produce a wide range of bioactive apocarotenoids. Considering that no detailed information is available in the literature regarding the occurrence of apocarotenoids in microalgae species, the aim of this study was to study the extraction and characterization of apocarot...
Microalgae accumulate a variety of compounds that form the basis for potential marketable products as whole cell biomass or as fractions after an extraction process. A cascading biorefinery approach aims at recovering and separating multiple algae compounds to valorise the complete biomass and to improve the economics of the value chain. This chapt...
A number of considerations must be examined when microalgal photobioreactors (PBRs) are designed, and choices regarding design, including materials choice, are highly dependent on the specific intended use. A PBR to be used for hydrogen production has different requirements than a PBR intended solely for algae biomass production, particularly as re...
Microalgal species commonly used and processed for use in foods and cosmetics
include Arthrospira (traditional name, Spirulina), Chlorella spp., Dunaliella spp.,
and Haematococcus spp. (Buono et al., 2014). The largest collection of microalgae
is the Collection of Freshwater Algae at the University of Coimbra, Portugal, where
over 4000 strains and...
Several species of microalgae and phototrophic bacteria are able to produce hydrogen under certain conditions. A range of different photobioreactor systems have been used by different research groups for lab-scale hydrogen production experiments, and some few attempts have been made to upscale the hydrogen production process. Even though a photobio...

Green microalgae for several decades have been produced for commercial exploitation, with applications ranging from health food for human consumption, aquaculture and animal feed, to coloring agents, cosmetics and others. Several products from green algae which are used today consist o...
Hydrogen production through biological routes is promising because they are environmentally friendly. Hydrogen production through biophotolysis or photofermentation is usually a two stage process. In the first stage CO2 is utilized for biomass production which is followed by hydrogen production in the second stage in anaerobic/sulfur-deprived condi...
Some green algae have shown the ability to produce hydrogen under anaerobic conditions. The production of hydrogen in green algae is catalyzed by hydrogenases, which are small monomeric enzymes with high conversion efficiency and high oxygen sensitivity. Most green algae analyzed to date where hydrogenase genes are detected, have been shown to cont...
Twenty-one species of green algae isolated from marine, freshwater and terrestrial environments were screened for the ability to produce H2 under anaerobic conditions. Seven strains found positive for H2 production under anaerobic conditions were also screened for the ability to produce H2 under sulfur (S) deprivation. In addition to the traditiona...
Many areas of algae technology have developed over the last decades, and there is an established market for products derived from algae, dominated by health food and aquaculture. In addition, the interest for active biomolecules from algae is increasing rapidly. The need for CO(2) management, in particular capture and storage is currently an import...
Profiles describing the relationships between growth, irradiance and temperature are important in the evaluation of microalgae
and cyanobacteria for biomass production, as well as for their general characterization. To get correct results culturing
chambers with plane parallel optical faces are needed. Only these give a defined light climate in the...

Colifast AS have developed an automated system for rapid detection of microorganisms, which is called Colifast Analyser (CA). The system combines an automated laboratory instrument, and a growth medium containing substrates which are cleaved into fluorogenic products by specific enzyme reactions. The instrument consists of incubator blocks, a robot...
