Sulphur (S) and selenium (Se) are chemically similar. Once Se is taken up, it substitutes S in S-containing amino acids. This study investigated the effect of on selenite accumulation microalga Nannochloropsis oceanica. [0–28 mM] concentrations 0 30 μM were tested. ≤ 3 mM led to decreased cell growth whereas cultures with ≥ 4 not limited. increased up 8-fold when using 2 28 mM. The average rela...

The aim of the present work was focused on optimising yield and quality biocrude obtained by hydrothermal liquefaction (HTL) Nannochloropsis gaditana. Temperature, reaction time microalga concentration were variables used to carry out an experimental factorial design with a central composite design. responses chosen nitrogen oxygen content in phase. A second-order model predict as function thes...

BACKGROUND Photosynthetic microalgae are considered a viable and sustainable resource for biofuel feedstocks, because they can produce higher biomass per land area than plants and can be grown on non-arable land. Among many microalgae considered for biofuel production, Nannochloropsis oceanica (CCMP1779) is particularly promising, because following nutrient deprivation it produces very high amo...

Electrocoagulation is a promising technology to harvest and concentrate microalgae while saving costs on secondary dewatering steps. However, the sacrificial electrodes release salts that impact media harvested biomass. This study evaluated effects of Fe, Zn, Mg Nannochloropsis oceanica harvesting elementary composition biomass supernatants. Moreover, plant bioavailability electrocoagulation mi...

The production of high-value bioproducts from microalgae biomass has been widely investigated. However, their is hindered by the expensive harvesting process. To date, flocculation followed DAF process accepted as one affordable approaches. In this study, use technique was attempted to harvest marine Nannochloropsis sp. Batch carried out using fabricated unit equipped with several compartments ...

In this study, antibacterial activity of Nannochloropsis oculata which were grown in proper culture condition was searched with their extracts that obtain by using different solvent (methanol, ethanol, chloroform). The effects algal evaluated disc diffusion method against L. garvieae, F. psychrophilum and Y. ruckeri. As the results it found chloroform N. showed strong activities, high resistant...
