Azolla microphylla Kaulf. is an aquatic nitrogen fixing pteridophyte commonly found in aquatic habitats including paddy fields. Methanolic extract of the fronds of A. microphylla was subjected to partial purification by solvent partitioning with diethyl ether and ethyl acetate followed by hydrolysis, and further partitioning with ethyl acetate. The two fractions, thus obtained were tested for a...

In this work, Azolla filiculoides was used for the bioremediation of a textile effluent and as potential sorbent rejection Congo red (CR9) dye from synthetic aqueous solution. The characterized, pot culture test carried out to assess physiological responses in controlled environment. response plants exposure emanating pollutants subordinate. BOD, COD, TDS removals were found be 98.2%, 98.23%, 9...

Nitrogen Fixation, Symbiotic Cyanobacteria, Photosynthesis, Respiration, Heterotrophic Growth Fructose supported the heterotrophic growth of the cyanobiont Anabaena azollae, isolated from the water fern Azolla filiculoides, and also enhanced its growth in the light by 2-3fo ld . Fructose was taken up at a high rate in the light and in the dark, in an energy-dependent reaction. The photosyntheti...
