TiO2 nanoparticles in seawater: Aggregation and interactions with the green alga Dunaliella tertiolecta

Ecotoxicology and Environmental Safety, 2018
Titanium dioxide nanoparticles (TiO2 NPs) have been widely employed in industrial applications, thus rising concern about their impact in the aquatic environment. In this study we investigated the chemical behaviour of TiO2 NPs in the culture medium and its effect on the green alga Dunaliella tertiolecta, in terms of growth inhibition, oxidative stress,

Effect of sulfate availability on phytoplankton stoichiometry

Journal of Phycology, Volume 61, Issue 4, Page 895-910, August 2025.
Abstract Sulfur (S) is a key element in multiple metabolic pathways of phytoplankton cells. The effect of S availability on phytoplankton elemental quotas and stoichiometry has been addressed in few studies, using a limited number of species and with contradictory results.

The Use of Flocculation as a Preconcentration Step in the Microalgae Harvesting Process

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT Flocculation is a widely utilized separation technique in colloid chemistry, the chemical industry, and wastewater treatment. However, its application in microalgal biomass production and downstream processing remains limited. Biomass harvesting represents a significant cost factor in large‐scale microalgae production, with the separation of ...

Two Isoforms of Dihydroxyacetone Phosphate Reductase from the Chloroplasts of Dunaliella tertiolecta [PDF]

Plant Physiology, 1993
Three isoforms of dihydroxyacetone phosphate reductase in extracts from Dunaliella tertiolecta have been separated by a diethylaminoethyl cellulose column chromatography with a shallow NaCl gradient. The chloroplasts contained the two major isoforms, and the third, minor form was in the cytosol.

Quantification of the total lipids in three aquaculture microalgae using BODIPY™ 505/515 stain and flow cytometry

Journal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract Microalgae are essential food sources for fish and shellfish aquaculture and contain abundant lipids with diverse fatty acid profiles. Quantification of total lipids in microalgae could assist commercial microalgal culture operations, harvest, and management in hatchery farms.
