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 ...

Ecotoxicity of Ag-nanoparticles on two microalgae, Chlorella vulgaris and Dunaliella tertiolecta [PDF]

open access: yesArchives of Biological Sciences, 2013
The increasing application of nanotechnology highlights the need to clarify and understand it. In this work, the subacute toxicity of Ag-NPs to the fresh water microalga Chlorella vulgaris and marine microalga Dunaliella tertiolecta were ...

Characterisation of the Dunaliella tertiolecta RbcS genes and their promoter activity in Chlamydomonas reinhardtii [PDF]

open access: yesPlant Cell Reports, 2004
The availability of highly active homologous promoters and terminators is critical in the development of a transformation system for the unicellular microalga Dunaliella tertiolecta. To facilitate transformation of this species, we isolated and characterised two native ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit genes (RbcS) including

Nutrient metal interactions and adaptive responses of Dunaliella tertiolecta to zinc and copper toxicity under phosphorus limitation [PDF]

open access: yesScientific Reports
Heavy metal pollution is a major environmental concern, especially in phosphorus-limited aquatic habitats. The growth of algae is negatively impacted by a variety of stressors, including fluctuations in heavy metal concentrations, phosphorus starvation ...

Effects of Burkholderia thailandensis rhamnolipids on the unicellular algae Dunaliella tertiolecta [PDF]

open access: yesEcotoxicology and Environmental Safety, 2019
The effects of rhamnolipids (RLs) produced and further purified from Burkholderia thailandensis, on the unicellular microalgae Dunaliella tertiolecta were investigated, in terms of RLs ability to affect algal growth, photosynthetic apparatus structure and energy flux, round and through photosystems II and I. Specifically, 24-48 h RLs-treated algae (RLs

Antiproliferative Activity of Violaxanthin Isolated from Bioguided Fractionation of Dunaliella tertiolecta Extracts [PDF]

open access: yesMarine Drugs, 2011
Dunaliella tertiolecta (DT) was chemically investigated to isolate molecules inhibiting cancer cell proliferation and inducing apoptosis in vitro. The potency to inhibit cell growth was used for the bio-guided fractionation and isolation of active ...

Phytosterols from Dunaliella tertiolecta Reduce Cell Proliferation in Sheep Fed Flaxseed during Post Partum [PDF]

open access: yesMarine Drugs, 2017
The post partum period is characterized by immunosuppression and increased disease susceptibility. Both phytosterols from microalga Dunaniella tertiolecta and dietary supplementation with n-3 polyunsaturated fatty acids (PUFA) influence cell ...
