The toxic profile of lawsone (2-hydroxy-[1,4]naphthoquinone) and a series of [1,4]naphthoquinone derivatives was evaluated against the brine shrimp Artemia salina and against the mollusk Biomphalaria glabrata, the main transmitting vector of schistosomiasis in Brazil. Of the seventeen compounds tested nine fell below the threshold of 100 microg/mL set for potential molluscicidal activity by the...
استفاده از گیاهان آبزی به واسطه داشتن ترکیب های مختلف در پیشگیری و درمان بیماریها از حدود 3000 سال پیش در چین رایج بوده است. جلبک سبز دونالیلا (dunaliella salina) نیز یکی از میکروجلبک های اکوسیستم های دریایی است که به واسطه داشتن ترکیب هایی نظیر کاروتنوئیدها مخصوصاً بتا-کاروتن، رتینال، آپوکاروتنوئیدها، کتون ها، آلدهیدها و اپوکسیدها که با ساختار شیمیایی خاص و روشهای بیوشیمیایی می توانند اکسیژن تک...
We report the genome sequence of Halomonas sp. strain A3H3, a bacterium with a high tolerance to arsenite, isolated from multicontaminated sediments of the l'Estaque harbor in Marseille, France. The genome is composed of a 5,489,893-bp chromosome and a 157,085-bp plasmid.
Dunaliella salina, lycopene and vitamin A Carotenoids especially betacarotene, vitamin A and lycopene have been shown to boost sperm parameters [2-5] Dunaliella salina is a microalgae which is a naturally rich source of mixed carotenoids including lycopene [6] Betacarotene, lycopene and vitamin A can reduce sperm DNA fragmentation and lipid peroxidation [1, 2] Vitamin A is an essential nutrient...
برخی از گونههای فیتوپلانکتون در شرایط نامساعد و در چرخه زندگی تولیدمثلی خود سیست تولید کرده که در رسوبات کف تهنشین میشوند و تحت شرایط مساعد مجدداً شکوفا شده و به ستون آب برمیگردند. بمنظور شناسایی دقیق مورفولوژی، گونههای فیتوپلانکتون در دو مرحلهی سیست و متحرک بررسی گردیدند زیرا برخی از سیستهای مشابه به فیتوپلانکتون متفاوتی تبدیل میشوند. هدف از این تحقیق، کشت سیستهای موجود در رسوبات خل...

We report the draft genome sequence of arsenite-oxidizing Halomonas sp. strain HAL1, isolated from the soil of a gold mine. Genes encoding proteins involved in arsenic resistance and transformation, phosphate utilization and uptake, and betaine biosynthesis were identified. Their identification might help in understanding how arsenic and phosphate metabolism are intertwined.
Background: The genus Dunaliella (Class – Chlorophyceae) is widely studied for its tolerance to extreme habitat conditions, physiological aspects and many biotechnological applications, such as a source of carotenoids and many other bioactive compounds. Biochemical and molecular characterization is very much essential to fully explore the properties and possibilities of the new isolates of Duna...

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...
