9 10 During the Mesozoic Era, dinoflagellates, coccolithophorids and diatoms became prominent 11 primary producers in the oceans, succeeding an earlier biota in which green algae and 12 cyanobacteria had been proportionally more abundant. This transition occurred during an 13 interval marked by increased sulfate concentration in seawater. To test whether increasing 14 sulfate availability facil...

The anaerobic digestion, AD, process presents a solution for sustainable waste management, greenhouse gas mitigation and energy production growing population needs requirements. Adopting biorefinery approach that utilises different feedstock may enhance support optimisation of the digestion process. Algae is promising could be used via Microalgal biomass rich in carbohydrates lipids; however, m...

The objective of this study was to determine whether the use electromagnetic field (EMF) 50 Hz frequency and magnetic induction 0.25 T could make for successful inactivation a phytoplankton species, namely, marine microalgae Tetraselmis suecica two bacteria strains ; Escherichia coli Enterococcus faecalis. A number laboratory tolerance experiments with selected organisms performed each microorg...

The article considers the use of salicylic acid as a stimulator microalgae growth. influence wide range concentrations on growth dynamics Tetra-selmis suecica in enrichment culture has been evaluated. Cultivation was carried out monoculture. An increase algal biomass measured by increasing number cells counted each experiment three Goryaev chambers under light microscope. duration experiments 1...
