Fatty Acid Production and Direct Acyl Transfer through Polar Lipids Control TAG Biosynthesis during Nitrogen Deprivation in the Halotolerant Alga Dunaliella tertiolecta

open access: yesMarine Drugs, 2021
The aims of this work were to evaluate the contribution of the free fatty acid (FA) pool to triacylglyceride (TAG) biosynthesis and to try to characterize the mechanism by which FA are assimilated into TAG in the green alga Dunaliella tertiolecta. A time-

Effect of the Culture Nutrients on the Biomass and Lipid Productivities of Microalgae Dunaliella tertiolecta

open access: yesChemical Engineering Transactions, 2013
This work analyses the influence of macro and micronutrients on the growth, biomass and lipid productivities of Dunaliella tertiolecta (D. tertiolecta), showing that with the exception of Nitrogen (N) and Iron (Fe), the other nutrients added to the ...

MICROALGAE AS TOCOPHEROL PRODUCERS [PDF]

open access: yesBiotechnologia Acta, 2014
Microalgae are able to accumulate considerable amounts of tocopherols (up to 4 mg/g dry weight). The content of α-tocopherol to plant oils is low, whereas microalgae contain up to 97% of the tocochromanols that provides high bioactivity.

Assessing sediment quality in Spanish ports using a green alga bioassay

open access: yesCiencias Marinas, 2008
Coastal zones are under environmental pressure due to human activities, and ports are the areas that probably present the highest levels of contaminants in their sediments.

Biosynthese von Glycerin in Dunaliella tertiolecta unter Salzstress [PDF]

open access: yesBIOspektrum
Abstract The microalgae Dunaliella tertiolecta phototrophically generates glycerol as an osmolyte in response to salt stress. This biogenic carbon sink is also a platform intermediate for the chemical sector. A synergistic genome and time resolved proteome analysis deciphered the metabolic pathways activated under salt stress. Immediately (30

Cost-effective fibrinolytic enzyme production by microalga Dunaliella tertiolecta using medium supplemented with corn steep liquor [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
A fibrinolytic enzyme from the microalga Dunaliella tertiolecta was produced under mixotrophic conditions using different corn steep liquor (CSL) concentrations ( 0 ≤ CLS ≤ 0.75%), purified using a combination of salting out and ion-exchange ...
