background pyrocatechol or 1, 2-dihydroxybenzene, or 2-hydroxyphenol is considered as apriority pollutant since it is harmful to organisms at low concentrations, and has been classified as hazardous pollutants. objectives the objective of this study was to examine whether azolla filiculoides, is able to remove pyrocatechol from aqueous solutions. materials and methods this study is an experimen...
BACKGROUND An ancient cyanobacterial incorporation into a eukaryotic organism led to the evolution of plastids (chloroplasts) and subsequently to the origin of the plant kingdom. The underlying mechanism and the identities of the partners in this monophyletic event remain elusive. METHODOLOGY/PRINCIPAL FINDINGS To shed light on this evolutionary process, we sequenced the genome of a cyanobact...
Using Azolla filiculoides , a candidate macrophyte species for ecological intensification, in small-scale aquaculture requires the investigation of potential effects fresh plant material not only on fish growth but also physiological status and responses to disease stress. In this study, juveniles giant gourami Osphronemus goramy reared into cages placed an outdoor pond were fed six weeks with ...
تحقیق حاضر به بررسی میزان رطوبت، پروتئین، چربی و خاکستر آزولای (Azolla filiculoides) وحشی و پرورشی به منظور کاربرد تغذیهای آن برای انسان و دام پرداخت. همچنین ترکیب اسیدهای چرب آزولا به عنوان یکی از اجزای مهم برای تصمیمگیری در رابطه با ارزش غذایی در هر یک از اشکال وحشی و پرورشی مقایسه گردید. نمونههای آزولا برای این منظور از منطقه پیر بازار تالاب انزلی جمعآوری و برای بررسی روند رشد و تکثیر در...
MicrosoftInternetExplorer4 Background and Objectives: Azolla Filiculoides as a non-living fern was used in a batch system to remove "Basic Blue 3", which is a cationic dye and a carcinogenic agent.Materials and Methods: We used a batch system by applying certain concentrations of dye contaminant and in the presence of a certain amount of adsorbent under optimum conditions. The main groups ...
Azolla nilotica does not occur in Egypt today, reaching as far north as central Sudan. Its spores have been recorded in sediment cores from the Nile Delta near Manzala Lake up to ca. 550 AD. As part of the CASSARINA Project on recent changes in ecosystems of North African lakes, short sediment cores, covering up to the last two centuries, were taken from the open water of the large Delta lagoon...
