Adaptation of the Photosynthetic Apparatus to Irradiance in Dunaliella tertiolecta [PDF]

Plant Physiology, 1990
The time course of adaptation from a high to a low photon flux density was studied in the marine chlorophyte Dunaliella tertiolecta. A one-step transition from 700 to 70 micromole quanta per square meter per second resulted in a reduction of doubling rate from 1.1 to 0.4 per day within 24 hours, followed by a slower accumulation of photosynthetic ...

Delayed fluorescence as a measure of nutrient limitation in Dunaliella tertiolecta

Journal of Photochemistry and Photobiology B: Biology, 2008
The applicability of the delayed fluorescence (DF) for the purpose of distinguishing the cells growing in different nutrient conditions was researched on the marine unicellular algae Dunaliella tertiolecta Butcher (Chlorophyta). The DF intensity (DFI), as a measure of living algal biomass, was compared with other biomass measures--the cell ...

Proteomic-based biotyping reveals hidden diversity within a microalgae culture collection: An example using Dunaliella

, 2015
Accurate and defendable taxonomic identification of microalgae strains is vital for culture collections, industry and academia; particularly when addressing issues of intellectual property.

Decrease of plasma cholesterol with the marine microalga dunaliella tertiolecta in hypercholesterolemic rats [PDF]

, 1994
Female Sprague-Dawley rats, whose plasma cholesterol level had been previously increased, were fed on a diet including 22% biomass of the marine microalga Dunaliella tertiolecta. This diet was compared to two control diets, one of casein and the other of

Polycyclic aromatic hydrocarbons stress affects fatty acids profile and LacsA (long-chain acyl-CoA synthetize) gene expression in Dunaliella

Applied Phycology
This study was conducted to evaluate the effects of different concentrations of two Polycyclic Aromatic Hydrocarbons (PAHs) on the profiles of soluble proteins and fatty acids and on LacsA (long-chain acyl-CoA synthesis) gene expression in Dunaliella ...

Light-driven growth rate-dependent volatile organic compound production reflects adaptative strategies in Dunaliella tertiolecta and Thalassiosira weissflogii

Frontiers in Photobiology
Phytoplankton are important producers of volatile organic compounds (VOCs) involved in atmospheric and ecological processes. VOC production can be sensitive to environmental conditions including light intensity and diel changes in photosynthetic ...

Exploring the Chemical Space of Macro- and Micro-Algae Using Comparative Metabolomics

Microorganisms, 2021
With more than 156,000 described species, eukaryotic algae (both macro- and micro-algae) are a rich source of biological diversity, however their chemical diversity remains largely unexplored.

Investigation of microalgal tolerance and growth in simulated tailings pond water containing naphthenic acids

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1877-1888, April 2026.
Abstract Oil sands tailings ponds, such as those in northeastern Alberta, present environmental challenges due to slow sedimentation, water entrapment, and toxic naphthenic acids (NAs), which hinder water reclamation. This study assessed the tolerance and biodegradation potential of Chlorella vulgaris (C.
