aquatic plants have been used prevalently in china since 3000 years ago due to having various chemical compounds for diseases prevention and cure. dunaliella salina is one of the micro algae in marine ecosystems containing beta-carotene, retinal, apocarotenoides, ketones, aldehydes and epoxides which enable it to absorb free radicals and produce singlet oxygen. in many studies, the anti-cancer...
The mechanism of abiotic stress tolerance is crucial for plants to survive in harsh condition and the knowledge of this mechanism can be use to solve the problem of declining productivity of plants or crops around the world. However in-depth description is still unclear and it is argued, in particular that there is a relationship between high salinity tolerance and the ability to tolerate high ...
Light could induce phosphorylation of light harvesting chlorophyll a/b binding proteins (LHCII) in Dunaliella salina and spinach thylakoid membranes. We found that neither phosphorylation was affected by glycerol, whereas treatment with NaCl significantly enhanced light-induced LHCII phosphorylation in D. salina thylakoid membranes and inhibited that in spinach. Furthermore, even in the absence...
conclusions light and temperature were both relevant factors that contributed to the growth and beta-carotene accumulation of the three d. salina strains, and nahco3 had significantly positive effects on growth. the degree of impact of the different factors on cell growth was temperature > nahco3 > light intensity > kno3 > co (nh2)2 > strains; the impact on beta-carotene accumulation was temper...
Olive mill solid waste (OMSW) is a pollutant waste coming from olive oil elaboration by the two-phase centrifugation system. OMSW has a high organic matter content and unbalanced carbon to nitrogen (C/N) ratio, 31/1, which avoids obtaining high methane yields in the anaerobic digestion of this waste. In the present study a microalgae, Dunaliella salina, was employed as co-substrate for the OMSW...
Glycerol is an important osmotically compatible solute in Dunaliella. Glycerol-3-phosphate dehydrogenase (G3PDH) is a key enzyme in the pathway of glycerol synthesis, which converts dihydroxyacetone phosphate (DHAP) to glycerol-3-phosphate. Generally, the glycerol-DHAP cycle pathway, which is driven by G3PDH, is considered as the rate-limiting enzyme to regulate the glycerol level under osmotic...
aluminum oxide nanoparticles are the most widely used nanoparticles in various industries.theincreasing use of nanoparticles in the past two decades and their entry into the industrial and non-industrialwaste water necessitates the assessment of potential effects of these substances in aquatic ecosystems. oecdstandard method was applied to determine the toxicity of this substance. after perform...
آثار مفید یا زیانبار یک گیاه بر سایر گیاهان از طریق آزاد کردن ترکیبات شیمیایی موسوم به آللوکمیکال ها به محیط، آللوپاتی نامیده می شود. در پژوهش حاضر، اثر آللوپاتیک عصاره های آبی برگ گیاه اسطوخودوس (lavandula angustifolia l.) بر الگوی رشد و قابلیت تولید بتاکاروتن در جلبک سبز تک سلولی dunaliella salina مطالعه شده است. بررسی عصاره ها نشان داد که میزان ترکیبات فنلی و همچنین قدرت آنتی اکسیدانی این عص...
This study investigated the regulation of the major light harvesting chlorophyll a/b protein (LHCII) phosphorylation in Dunaliella salina thylakoid membranes. We found that both light and NaCl could induce LHCII phosphorylation in D. salina thylakoid membranes. Treatments with oxidants (ferredoxin and NADP) or photosynthetic electron flow inhibitors (DCMU, DBMIB, and stigmatellin) inhibited LHC...
