OPTIMIZATION OF SALT CONCENTRATIONS FOR A HIGHER CAROTENOID PRODUCTION IN DUNALIELLA SALINA (CHLOROPHYCEAE) 1

Results showed that at 1.5–3.0 M NaCl, D. salina produce appreciable antioxidant level, but, once it reaches its growth maximum, a salt addition up to 4.5‰M could enhance its carotenoid yield.

Phenolic profile of Dunaliella tertiolecta growing under high levels of copper and iron

The use of reversed-phase high-performance liquid chromatography (RP-HPLC) permitted the identification of 14 phenolic constituents and Gentisic acid, (+) catechin and (−) epicatechin, the most prominent phenolic compounds detected in the algae extracts, showed high antioxidant activity in inhibiting 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals.

Analysis of the Physiological and Molecular Responses of Dunaliella salina to Macronutrient Deprivation

It is proposed that the carotenoid biosynthesis pathway of D. salina is regulated at both the transcriptional and posttranscriptional levels and that a complex crosstalk occurs at the physiological and molecular levels in response to the deprivation of different nutrients.

Transcriptomic sequencing reveals the response of Dunaliella salina to copper stress via the increased photosynthesis and carbon mechanism.

It is shown that the enhanced growth and photosynthesis and carbon mechanism in D. salina can be triggered by copper, which will lay a firm foundation for future breeding and carotenoid production, further highlighting the underlying application of D.salina as a functional food.

Comparison of selenium-induced antioxidant responses and bioaccumulation in two strains of the halotolerant alga Dunaliella salina

It can be concluded that Dunaliella salina Hoze-soltan may be a better candidate for selenium bioremediation of a high salinity environment.

Regulation of activity and gene expression of antioxidant enzymes in Ulva fasciata Delile ( Ulvales , Chlorophyta ) in response to excess copper

It is demonstrated that the maintenance of antioxidant homeostasis and the induction of activities of antioxidant enzymes via enhanced gene expression are used by U. fasciata to cope with the Cuinduced oxidative stress, but the defense capacity cannot sufficiently alleviate oxidative damage occurring under the condition of higher Cu concentrations.

Producing Cu-loaded algae for feeding experiments: effects of copper on Parachlorella kessleri

Tests show that P. kessleri is largely unchanged in its nutritional value when exposed to Cu at levels of up to 6 µmol L−1, with chlorophyll contents and growth rate being the most sensitive indicators.

Carbamazepine-mediated pro-oxidant effects on the unicellular marine algal species Dunaliella tertiolecta and the hemocytes of mussel Mytilus galloprovincialis

The significant relationships occurred among the tested biological parameters in both bioassays, further reinforce CBZ-mediated pro-oxidant effects on species, widely used in ecotoxicological and toxicological studies and provide a more comprehensive view on its environmental fate and ecot toxicological risk evaluation.

Dunaliella salina was isolated from Maharlu salt lake in Shiraz, Iran, and was analyzed forthe effects of salinity stress on its growth, pigment content and ascorbate peroxidase activity.

On the Factors Which Determine Massive beta-Carotene Accumulation in the Halotolerant Alga Dunaliella bardawil.

The results are interpreted as indicating a protecting effect of beta-carotene against injury by high irradiance under conditions of impairment in chlorophyll content per cell.

Effect of Ni2+ on Early Stages of Chlorophyll Biosynthesis and Pheophytinization in Euglena gracilis

The effect of Ni2+ on the early stages of chlorophyll biosynthesis and pheophytinization in Euglena gracilis cells was studied and it seems likely that, by affecting heme synthesis, Ni2- increases the activity of the ALA production system.

Copper accumulation, synthesis of ascorbate and activation of ascorbate peroxidase in Enteromorpha compressa (L.) Grev. (Chlorophyta) from heavy metal‐enriched environments in northern Chile

It is suggested that E. compressa tolerates a copper-enriched environment, and the accompanying oxi- dative stress, through the accumulation of copper, activation of ascorbate peroxidase, synthesis of asCorbate (accumulated as dehydroascorbate) and consumption of glutathione and water-soluble phenolic compounds.

Effect of cobalt on growth, pigments and the photosynthetic electron transport in Monoraphidium minutum and Nitzchia perminuta

A reduction in the amount of O2 evolved by each alga in response to increasing Co2+ concentrations showed an increase in O2 evolution for both M. minutum and N. perminuta, while the effect of the heavy metal on respiration showed that higher Co2+.

Antioxidant Modulation in Response to Metal-Induced Oxidative Stress in Algal Chloroplasts

It is indicated that heavy metals are able to induce oxidative stress in chloroplasts of G. polyedra, particularly under acute conditions, and the maintenance of a high antioxidant capacity within chloroplast seems to be an important strategy during acclimation of Gonyaulaxpolyedra to chronic metal stress.
