[ 1 ] - Transcript levels of phytoene desaturase gene in Dunaliella salina Teod. as affected by PbS nanoparticles and light intensity
Phytoene synthase (Psy) and Phytoene desaturase (Pds) are the first two regulatory enzymes in the carotenoids biosynthetic pathway. The genes Psy and Pds are under transcriptional control in many photosynthetic organisms. In the present study, using quantitative real time- PCR (qRT-PCR), the effects of uncoated and gum-Arabic coated PbS nanoparticles (GA-coated PbS NPs) and light intensity on t...
[ 2 ] - Evaluation of antioxidant potential and reduction capacity of some plant extracts in silver nanoparticle synthesis
The green synthesis of metallic nanoparticles is an active research area in nanotechnology. In the present study, antioxidant potential, total reducing capacity and silver nanoparticles (Ag NPs) synthetic potential of methanolic leaf extracts of seven plant species were evaluated and compared. Antioxidant capacity, expressed as µmol Trolox equivalents g-1 DW (µmol TE g-1 DW), ranged from 116.0 ...
[ 3 ] - Synthesis and coating of nanosilver by vanillic acid and its effects on Dunaliella salina Teod.
Plant phenolics have high reducing capacity which can be exploited in the synthesis of nanomaterials. In the present study, phytoreductant vanillic acid is used to produce and coat silver nanoparticles. The effects of Ag nanoparticles on the unicellular green algae D. Salina were then investigated. Under optimum pH and temperature, silver ions were reduced to silver metal by vanillic acid. The...
[ 4 ] - Molecular identification of Dunaliella viridis Teod. strain MSV-1 utilizing rDNA ITS sequences and its growth responses to salinity and copper toxicity
In addition to biochemical, physiological and morphological analysis, molecular studies provide additional information for establishing phylogenetic relationships among different species and strains of the genus Dunaliella. In the present study, based on neighbor- joining analysis of the nuclear rDNA ITS sequence, a novel strain of the green algae Dunaliella viridis was identified from Maharlu ...
[ 5 ] - Effect of phenanthrene oil pollutant on physiological and biochemical characteristics of vetiver plant (Chrysopogon zizanioides)
Vetiver plant is from Poaceae family with high resistance, environmental compatibility and high ability for pollutants absorption, so can be used in environmental pollutions removal processes. Among petroleum compounds, polycyclic aromatic hydrocarbons are known as primary pollutants due to their stability in the environment. Phenanthrene usually has the highest concentration and most polluting...
