We examined various media and conditions to isolate symbiotic cyanobacteria from the leaf cavities of Azolla spp. Cyanobacteria survived and multiplied to a limited extent on a medium with fructose, Casamino Acids, yeast extract, and NaNO(3) under 1% O(2). These cyanobacteria were antigenically identical to the endosymbionts.
pollution of water resources by various pollutants is nowadays a global environmental issue. among the different type of water pollutants, dye represents a major polluting group. in this study, azolla filiculides roots have been used for adsorption of malachite green (mg), a cationic dyed from aqueous solution. in this study, effects of operating parameters such as initial concentration of dye ...
The possibility of using some organic wastes as growth media for English daisy, plus some fertilization methods, was investigated in a factorial experiment, based on a completely randomized blocks design with 45 treatments and three replications. The first factor was different growth media and the second factor was three methods of fertilization including without fertilization (control), fertil...
In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...
Background and purpose: The presence of phenol and its derivatives in water and wastewater are of major concern because of their toxicity and threat to human life and environment. The aim of this study was determination of the modified lemna minor and azolla in phenol adsorption. Materials and methods: In this emperical-lab study, the washed lemna minor and azolla was used as adsorbents. The e...
