Effects of an alginate oligosaccharide mixture (AOM) on Nannochloropsis oculata, a unicellular marine microalga, were investigated. The growth of N. oculata was significantly promoted by AOM in a concentration-dependent manner. The maximum effect was attained at 20 mg/ml, at which the growth rate of the alga became nearly 5 times higher than that of control without AOM. The growth-promoting eff...

CO2 biofixation was investigated using tubular bioreactors (15 and 1.5 l) either in the presence of green algae Chlorella vulgaris or Nannochloropsis gaditana. The cultivation was carried out in the following conditions: temperature of 25 °C, inlet-CO2 of 4 and 8 vol%, and artificial light enhancing photosynthesis. Higher biofixation were observed in 8 vol% CO2 concentration for both microalgae...

We studied the growth performance of Nannochloropsis oceanica IMET1 under various culture conditions, including different CO2 concentrations, temperature, or light intensities compared with that of N. gaditana CCMP526. When CO2 concentrations were changed, the growth rates of N. oceanica IMET1 and N. gaditana CCMP526 were the highest at a CO2 concentration of 2 vol%. N. oceanica IMET1 had a hig...

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...
