The ocean consists of versatile domain lives which can be exploited for human health benefits because diversified secondary metabolites. Seaweeds, generally called macroalgae, are commonly found in the coastal region Bay Bengal. But none them were investigated properly their biological activities. Hence, this study was performed to investigate antioxidant, antimicrobial, cytotoxic and membrane ...
Aquatic ecosystems are the final absorbers of various pollutants, so require complex monitoring to control their condition. Macrophytes and other aquatic plants serve as reliable indicators hydro ecological state, they provide an integral assessment environment in time space. Changes chlorophyll a b content ratio rigid hornwort (Ceratophyllum demersum L.) leaves depending on water chemical para...
در این تحقیق عملکرد شارهای نوری مدل های مختلف لامپ های فلوئورسنت خطی بر افزایش بایومس گیاه آبزی Ceratophyllum demersum و رشد فرشته ماهی (Pterophyllum scalare) بررسی شد. بدین منظور از لامپ های فلوئورسنت مدل 8T5، T4...
In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated on Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn contents of macrophyte tissues increased. As a result, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the m...
Abstract The recovery or reconstruction of aquatic vegetation has recently been reported as a result water quality improvement after anthropogenic eutrophication. objectives this study were: to investigate long-term trends in abundance relation decreasing fertility and present new directions changes the submerged structure, species richness, biodiversity Lake Kuźnickie (western Poland) with per...
Harmful substances in the wastewater negatively affect ecological balance by reducing dissolved oxygen concentration. High phosphorus and nitrogen compounds discharged into surface water resources may cause to eutrophication, due increased algal growth. In this study, Elodea densa (Egeria), Lemna minor (Duckweed), Micranthemum micranthemoides (Micra), Pistia (Water Lettuce), Ceratophyllum demer...
