Biologically active molecules from marine microalgae
Diatoms are unicellular photosynthetic microalgae responsible for approximately 40% of marine primary productivity. This algal class has traditionally been regarded as providing the bulk of the food that sustains the marine food chain to top consumers and important fisheries. However, this …

Fatty acid metabolism of marine microalgae
… (PUFA) were elucidated in two heterotrophic, marine microalgae; Schizochytrium sp. and Crypthecodinium cohnii. PUFA-requiring auxotrophs of both of these algae were created and used as tools for studying PUFA biosynthetic pathways. Additionally, equilibrium radio-labeling techniques were …

Biofuels from Liquefaction of Marine Microalgae: Production, Upgrading, and Environmental Impacts
… Hydrothermal liquefaction (HTL) of microalgae is a promising conversion technology in which algal biomass is treated as an aqueous slurry under high temperature and pressure. Because the HTL process uses the whole biomass, increasing lipid content during cultivation is not essential. …

Microbial flocculation for large scale harvesting of marine microalgae for the production of biodiesel.
… for the production of biodiesel from the marine microalga Pleurochrysis carterae. The ideal process required the consideration of factors such as cost, reliability and low levels of contamination in the final product. However, a review of harvesting literatures revealed that there to be no …

The effects of growth conditions on the elemental and biochemical composition of the diatom Thalassiosira weissflogii and the haptophyte Emiliania huxleyi
… of physiology and biochemical composition of microalgae. Temperature and light intensity are important environmental factors regulating the growth of microalgae. In this study, the elemental and biochemical composition were measured in 2 marine microalgae under different temperatures and light …

Characterization of Value Added Proteins and Lipids form Microalgae
Microalgae have been so far identified as the major producers of organic matter through their photosynthetic activities. In the present work, Nannochloris sp. and Amphora sp., two marine microalgae, have been investigated for proteins and lipids production. Protein fraction was quantified using …

Improving biomass of the marine microalga Nannochloropsis oculata by chemical elicitation
Marine microalgae are of particular interest due to their ability to biosynthesise specialised metabolites with a variety of important properties, such as antioxidant and antimicrobial potential. Neutral lipids produced by microalgae are also of huge importance because of their desirable …

An Evaluation of the risks to food safety and shellfish farming in Great Britain,posed by marine biotoxins from, current and future emerging, marine microalgal species
Harmful marine microalgae are a global concern, impacting human and ecosystem health as well as having socioeconomic impacts for coastal communities. The changing world climate has an impact on marine organisms including the harmful algal species. These changes will have impacts on species already …

Enhancing the production of Omega-3 polyunsaturated fatty acids in marine diatoms
… omega-3 polyunsaturated fatty acids are marine microalgae, which form the base of the aquatic food web. One alternative source of our ever diminishing stocks of fish and fish oil is via the cultivation of these microorganisms. Unfortunately, these microalgae, of which diatoms are the …

Effect of UV-A irradiance on lipid accumulation in Nannochloropsis oculata
The marine microalgae <italic>Nannochloropsis</italic> spp. are of both ecological and economic importance as they contribute to the base of the food chain of marine systems, and can accumulate a considerable amount of lipids. Their lipids can be grouped into two categories, storage lipids, which …

Design of a Nutrient Reclamation System for the Cultivation of Microalgae for Biofuel Production and Other Industrial Applications
… high cost of supplying essential nutrients to microalgae cultures. With microalgae cells having relatively high nitrogen contents (4 to 8%), the N fertilizer cost in industrial-scale production is significant. In addition, the disposal of the large volumes of cell residuals that are generated …

Characterization of Fresh Water Microalgae from East Tennessee for Biodiesel Production
… unable to meet the existing demands for fuel. Microalgae are a promising source for biodiesel because of its relatively faster growth rate, availability, and lipid content. Microalgae (JC and BT) growing in local water bodies were collected, selected on section media containing antibiotics, and …

The aggregation of clay minerals and marine microalgal cells : physicochemical theory and implications for controlling harmful algal blooms
… added). The electrophoretic mobility (EPM) of marine microalgae displayed a small range of negative values. While the values were smaller that those reported from freshwater species, these results confirmed earlier assumptions that marine species carry a negative charge like their freshwater …
