The growth of the aquaculture sector leads to a demand for sustainable feed ingredients. Prebiotics are potential ingredients that can promote improved performance species without use antimicrobials. This study investigated Azolla pinnata as candidate prebiotic source. Prebiotic characteristics and dietary effect commercial diet (CD) with varying pulverised azolla (PA) inclusion was evaluated. ...

Introduction Water is an indispensable part for the sustenance of mankind and the increasing awareness about the environment; especially aquatic ecosystems have attracted the attention of researchers worldwide. A definite need exists to develop a low cost and eco-friendly technology to remove pollutants particularly heavy metals, thereby improving water quality. Phytoremediation offers an attra...

Cyanobacteria constitute one of the largest subgroups of Gram-negative photosynthetic prokaryotes and are of great evolutionary antiquity, dating back to the Precambrian (2.8–3.5 billion years ago). They are found worldwide in highly diverse ecosystems, from aquatic (limnic and marine) habitats to terrestrial systems and from polar to tropical regions of the globe. In terrestrial systems, nitro...

A field experiment was conducted at Agricultural College & Research Institute, Tamil Nadu University, Madurai during 2021to quantify the GHG emission in puddled rice, ADT 54. The laid out Randomized Block Design with four replications treatments, T1 - SRI method of rice cultivation organic farming SOP, T2 inorganic T3 T1+BGA application @ 10 kg ha-1, T4 T2+ BGA T5 -T1+Azolla 250 T6 -T2+ Azo...

Water is vital for humans and other living things, but water pollution has become a significant issue today. Various anthropogenic agricultural, industrial, home activities produce multiple organic inorganic substances dissolved or suspended in water. The goal of wastewater treatment thus twofold: to reduce while also maintaining the supply demand. It based on three 3 Rs: reduce, reuse, recycle...

The textile dyes are considered as major environmental problems. The dyes can be removed by various methods. Therefore, this study aimed to evaluate the adsorption rate of Reactive Red 198 (RR198) from aqueous solution by activated Azolla filiculoides. This was an empirical-lab study. The Azolla was used as an adsorbent to remove Reactive Red 198 dye. The effect of various parameters was invest...
