Microalgal neutral lipids [mainly in the form of triacylglycerols (TAGs)], feasible substrates for biofuel, are typically accumulated during the stationary growth phase. To make microalgal biofuels economically competitive with fossil fuels, generating strains that trigger TAG accumulation from the exponential growth phase is a promising biological approach. The regulatory mechanisms to trigger...

A microfluidic on-chip imaging cell sorter has several advantages over conventional cell sorting methods, especially to identify cells with complex morphologies such as clusters. One of the remaining problems is how to efficiently discriminate targets at the species level without labelling. Hence, we developed a label-free microfluidic droplet-sorting system based on image recognition of cells ...

We tested different alga-bacterium-archaeon consortia to investigate the production of oil-like mixtures, expecting that n-alkane-rich biofuels might be synthesized after pyrolysis. Thermosipho globiformans and Methanocaldococcus jannaschii were cocultured at 68°C with microalgae for 9 days under two anaerobic conditions, followed by pyrolysis at 300°C for 4 days. Arthrospira platensis (Cyanoba...

Microalgae are increasingly used in the production of various industrial chemicals. Lipids from major microalgae crops similar to lipids obtained oilseed plants and can be converted into biodiesel, moreover, more advantageous than oil many ways. Therefore, biodiesel technology is a current interesting research topic. The effect salinity nutrient medium on growth lipid productivity marine Dunali...

Abstract Purpose Dunaliella is a halophilic genus of microalgae with high potential in the global food market. The microalgal cultivation process contributes to not only economic impact but also environmental impact, especially regarding artificial medium composition. In this context, life cycle assessment was carried out analyze impacts associated components modified Johnson (MJM) and predict ...

Copepods serve as a major link in marine food webs, bridging the energy transfer from primary producers to higher trophic levels. Oceanic warming is linked reduced concentrations of essential fatty acids (FA) phytoplankton, namely eicosapentaenoic acid (EPA, 20:5ω3) and docosahexaenoic (DHA, 22:6ω3), it remains largely unknown if copepods have capacity endure. The calanoid Temora longicornis ha...

Using chlorophyll/P700 ratios, the size and number of photosynthetic units were estimated, as a function of light-shade adaptation in two species of marine phytoplankton: Skeletonema costatum, a diatom, and Dunaliella tertiolecta, a chlorophyte. In the diatom, light-shade adaptation is characterized primarily by changes in the size and not the number of P700 units, whereas in the chlorophyte, o...
