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.

Effects of centrifugal stress on cell disruption and glycerol leakage from Dunaliella salina [PDF]

, 2015
Dunaliella salina accumulates large amounts of intracellular glycerol in response to the increases in salt concentration, thus is a potential source for producing fuel grade glycerol as an alternative to biodiesel-derived crude glycerol. D.

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 ...

Growth and biochemical profile of juvenile mussels (mytilus galloprovincialis Lmk) fed on different algal diets [PDF]

, 1994
The food value of different microalgal diets to juvenile Mytilus galloprovincialis Lmk was assessed. Three different marine microalgae species (Tetraselmis suecica, Dunaliella tertiolecta and Phaeodactylum tricornutum) were fed singly and in various ...

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.
