One hundred and twenty, one week old, Cobb 400 broiler chickens were randomly distributed into three dietary treatments having four replicates each with ten birds. The birds of the control group (T1) were fed a basal diet (23.16% CP 1-3 weeks & 19.68% CP 3-6 weeks) while the other two groups were offered the treatment diets (T2& T3) replacing 4.50% or 5.50%, of the dry matter of the basal diet ...

This experiment was performed to investigate the effect of Azolla and rice straw mixed compost in peat substitution on Dieffenbachia amoena. Factorial experiment based on a completely randomized design with two factors of nutrient solution in 2 levels (1- without solution, 2- with 130 mg N/ l, 32 mg P /l and 117 mg K/ l) and 5 levels of Azolla and rice straw mixed compost (zero, 15, 30, 45 and ...

this study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by azolla caroliniana.  the experimental investigations have been carried out using azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), ph (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). the maximum removal ...

Anaerobic (microaerophilic) acetylene reduction by Azolla caroliniana Willd. was dependent on light and saturated at approximately 450 foot candles. Maximum rates of acetylene reduction were 60 nmoles/mg chlorophyll minute. However, rates of 25 to 30 nmoles/mg chlorophyll minute were more common.The growth of Azolla for 35 days with nitrate or urea as a nitrogen source decreased the rate of ace...

Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...

 The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation.  The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

The genus Azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics, and warm temperate regions of Africa, Asia, and America. For several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. Hg, Pb, Cr and Cd) through wastewater treatment or for elimination of...

climatic conditions of guilan have caused to develope azolla growth in wetland and ponds. regarding environmental problems of azolla accumulation, a study was conducted to investigate impact of composted azolla with nutrient solution on the growth of dracaena in replacement of peat in ornamental plants and flower research station, lahijan, iran. the control treatment was a 2:1 ration of peat: p...

Azolla is an aquatic pteridophyte widely distributed in the water bodies. It has been traditionally used as a biofertilizer for rice paddy fields owing to its potential to fix atmospheric nitrogen [1]. In addition to this it has several other uses and Wagner [2] referred it as “green gold mine”. The plant system has the inherent capacity to synthesize several biologically active constituents wh...

The free amino acid and ammonia pools of Azolla caroliniana were analyzed by quantitative column chromatography on columns capable of separating all of the nitrogenous constituents normally found in physiological fluids. Comparisons were made of plants containing symbiotic algae and grown on nitrogen-free media, plants grown on media containing nitrate, and algae-free plants also grown on nitra...
