The green microalgae Dunaliella genus is known for the production of high added value molecules. In this study, strain AL-1 was isolated from the Sebkha of Sidi El Hani (Sousse, Tunisia). This isolate was identified both morphologically and genetically via 18S rRNA gene sequence as a member of the genus Dunaliella. Strain AL-1 was found to be closely related to Dunaliella salina, Dunaliella qua...
The effects of osmotic shocks on polyphosphates and on the vacuolar fluorescent indicator atebrin have been investigated to test whether acidic vacuoles in the halotolerant alga Dunaliella salina have a role in osmoregulation. Upshocks and downshocks induce different patterns of polyphosphate hydrolysis. Upshocks induce rapid formation of new components, tentatively identified as 5 or 6 linear ...
Under high light (HL) stress, astaxanthin-accumulating Haematococcus pluvialis and β-carotene-accumulating Dunaliella salina showed different responsive patterns. To elucidate cellular-regulating strategies photosynthetically and metabolically, thylakoid membrane proteins in H. pluvialis and D. salina were extracted and relatively quantified after 0 h, 24 h and 48 h of HL stress. Proteomic anal...
Dunaliella salina is currently one of the most commercially valuable microalgae species in world. In reponse to selenite, D. a with high selenium content, thereby increasing its value, which crucial for economic value as nutrional supplement. However, effects selenite on are still unclear, and molecular mechanism response stress also elusive. Here, order study corresponding regulatory mechanism...
هدف: هدف از این مطالعه بررسی اثر امواج فراصوت بر رشد و برخی شاخص های فیزیولوژیکی در کشت جلبک تک سلولی dunaliella salina بود. مواد و روش ها: امواج فراصوت با فرکانس 40 کیلو هرتز و توان w/cm35، به کشتهای سلولی در روز چهاردهم واکشت در قالب طرح کاملا تصادفی با 3 تکرار اعمال شد. مدت زمان تابش امواج فراصوت به سلولها 0، 5/2، 5 و 10 دقیقه بود. شاخص های مورد اندازه گیری عبارت بود از: رشد سلولی، پروتئ...
The effects of some pretreatments including blue-green and green algae and minerals on the induction of me-tabolic and biochemical process of germination were studied in Dracocephalum kotschyi Boiss. seeds. The seeds were pretreated with green algae Spirulina platensis, Chlorella vulgaris and Dunaliella bardawil or D. IR-1 (Isolated from Gave-Khooni-salt marsh) and modified Johnson nutrient med...
