The aim. Today we are witnessing the actualization of research on plant sources for pharmaceutical and food industries. It is caused by a significant increase in demand these types resources. Therefore, variety case studies aimed at identifying characteristics resources, becoming more actual too. In accordance with this need, present work aims to identify relationship between content flavonoids...
The alxM gene encoding a D-mannuronan-specific alginate lyase has been cloned from a marine bacterium isolated as an epiphyte on the brown alga, Sargassum fluitans. Expression of this gene in Escherichia coli provides a source of this enzyme for probing alginate structure and modifying the mannuronan-rich alginate polymers produced by bacterial pathogens.
این مطالعه با هدف سنتز نانوذرات نقره با استفاده از جلبک دریایی sargassum angustifolium با روش زیستی خارج سلولی و بررسی اثرات آن بر وضعیت اکسیدان/آنتی اکسیدان، ایمنی و فلور باکتریایی در ماهی کپور معمولی انجام شد. پس از تهیه عصاره از جلبک سارگاسوم و سنتز نانوذرات نقره از طریق اضافه کردن نیترات نقره به عصاره جلبک، اقدام به تعیین ویژگی ها و مشخصه یابی نانوذرات نقره با استفاده از دستگاه های طیف سنج ...
BACKGROUND The preference for a fairer skin-tone has become a common trend among both men and women around the world. In this study, seaweeds Sargassum polycystum and Padina tenuis were investigated for their in vitro and in vivo potentials in working as skin whitening agents. Seaweed has been used as a revolutionary skin repairing agent in both traditional and modern preparations. The high ant...
The antibacterial activity of crude extracts of Sargassum longifolium and Gracilaria corticata collected from the Gulf of Mannar Coast, Tamilnadu, India against common shrimp pathogens were tested by disc diffusion method. Three different solvents namely aqueous, ethanol and methanol were used for extraction. The qualitative phytochemical analysis revealed the presence of carbohydrates, protein...
BACKGROUND AND OBJECTIVES Sixty ethanol extracts of marine flora of Baja California Sur (Mexico) were screened to evaluate the reversing effect of the bacterial resistance to antibiotics in combination with a sublethal concentration of ampicillin or erythromycin. MATERIALS AND METHODS The activity was assayed by using a modification of the classical agar-diffusion method against 3 resistant, ...
the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...
this experiment was carried out to investigate the effects of supplementing two macroalgae Sargassum cristaefolium and Gracilaria pygmaea extracts in feed on some growth indices, hematology and blood constituents of juvenile rainbow trout (Onchorhynchus mykiss). Rainbow trout were randomly divided into four groups: a control group was fed with basal diet, and three treated groups fed with basal...
Phytohormones are present in seaweeds but little is known about occurrence and content of them in seaweeds of Persian Gulf. The aim of this study was extraction of abscisic acid and gibberellin in Sargassum muticum and Gracilaria corticata. The seaweeds were collected bimonthly over one year at Bushehr coasts, Persian Gulf, during a range of environmental conditions. We explored new HPLC method...
