Energy crises and environmental pollution have caused considerable concerns; duckweed is considered to be a promising new energy plant that may relieve such problems. Lemna aequinoctialis strain 6000, which has a fast growth rate and the ability to accumulate high levels of starch was grown in both Schenk & Hildebrandt medium (SH) and in sewage water (SW). The maximum growth rates reached 10.0 ...

Acid mine drainage (AMD) is a by-product of the mining industry that has a detrimental effect on aquatic plant and animal life due to high load of heavy metals and sulfates. In the present study, the toxic and genotoxic potential of AMD prior to and following combination of neutralization/electrocoagulation processes was evaluated using several bioassays and selected parameters. Regardless of p...

Duckweed, a small flowering plant which comes from Lemnaceae family, has been rising in popularity to many researches and applications for its numerous valuable functional properties. One of special features is fast growing easily adapted various types regions makes it attractive be manipulated including biofuel production, waste water treatment also pharmaceutical medicinal purposes. Pectin th...

Boron (B) is often found in polluted and desalinated waters. Despite its potentially environmental damaging effects, efficient treatments are lacking. The duckweed Lemna gibba has been shown to remove toxic elements from water; however, its applicability to B removal is unknown. In this study, L. gibba was examined for its tolerance to B in water and its B removal efficiency. Duckweed plants we...

We have studied the mechanism of UV protection in two duckweed species (Lemnaceae) by exploiting the UV sensitivity of photosystem II as an in situ sensor for radiation stress. A UV-tolerant Spirodela punctata G.F.W. Meyer ecotype had significantly higher indole-3-acetic acid (IAA) levels than a UV-sensitive ecotype. Parallel work on Lemna gibba mutants suggested that UV tolerance is linked to ...

The dyes used in the production of textile industry are toxic substances that resistant to biological treatment. Most them have highly complex polymer structures. Salicylic acid (SA) is an important hormone produced by plants provides tolerance many biotic and abiotic stress factors. Duckweed (L. minor L.) free floating plants. These been laboratory toxicological studies researchers for reasons...
