Na+/H+ exchange activity in whole cells of the halotolerant alga DunaIfeila saUna can be elicited by intracellular acidification due to addition of weak acids at appropriate external pH. The changes in both intracellular pH and Nat were followed. Following a mild intracellular acidification, intracellular Nat content increased dramatically and then decreased. We interpret the phase of Nat influ...
The halotolerant alga Dunaliella salina is a model for stress tolerance and is used commercially for production of beta-carotene (=pro-vitamin A). The presented draft genome of the genuine strain CCAP19/18 will allow investigations into metabolic processes involved in regulation of stress responses, including carotenogenesis and adaptations to life in high-salinity environments.
beta-carotene is a carotenoid and known as the most famous natural pigment. microalgae are the most important sources for beta-carotene production. due to the high sterilization cost of pure culture, in this study for the first time, growth, amounts of beta-carotene and chlorophyll in caspian sea microalgae under nutrient deficiencies stress, have been measured and compared with pure microalgae...
We analyze the influence of greenhouses in cultivation phytoplankton. For this we propose a model for marine green algae Tetraselmis suecica, and adapt it to four other species (Spirulina platensis, Dunaliella salina, Phaeodactylum tricornutum Chlorella vulgaris). Experiments under greenhouse were carried out shifting temperature two raceways compared reference raceway with free evolving temper...
Dunaliella salina has been shown to have antioxidant property and induce apoptotic cell death of human cancer cells in vitro. However, there is no information available on D. salina showing an antileukemia effect or immunomodulatory activity in vivo. This study applied D. salina to syngeneic leukemia-implanted mice (BALB/c and WEHI-3) to investigate its immunological and antileukemia properties...
Nannochloropsis salina was grown on a mixture of standard growth media and pre-gasified industrial process water representing effluent from a local biogas plant. The study aimed to investigate the effects of enriched growth media and cultivation time on nutritional composition of Nannochloropsis salina biomass, with a focus on eicosapentaenoic acid (EPA). Variations in fatty acid composition, l...
As a rapidly-evolving global technology, nanotechnology has presumably brought drastic changes to our lives in the past two decades using engineered nanoparticles, whose penetration into industrial and non-industrial wastewater requires examination of their probable effects in aquatic ecosystems. The main objective of this work is to study the toxicological and biological effects of nanomateria...
The marine microalgae Dunaliella salina holds significant economic value due to its rich content of β-carotene, a natural pigment with high antioxidant capacity, immune-stimulating properties, and crucial role in reactions vitamins C E. This study evaluated the effects light factors on growth biosynthesis β-carotene strain isolated from coastal waters Central Vietnam. was cultured static f/2 me...
جلبک dunaliella جنس چیره تک سلولی یوکاریوت دریاچه ارومیه است که در سال های اخیر به علت خشکسالی شدید دریاچه ارومیه تراکم جمعیت آن به شدت کاهش یافته است. در پژوهش حاضر، تنوع گونه های مختلف این جنس با روش مولکولی در تعدادی از ایستگاه های دریاچه ارومیه بررسی شد. کولی با انجام واکنش زنجیره ای پلیمراز (pcr) و استفاده از جفت پرایمر ژن 18srdna، گونه های مختلف این جنس شناسایی شد. نمونه برداری و جداسازی ...
