Introduction: Chromium is among the important heavy metals which is found in most industrial wastes and is associated with both health and environmental risks. Therefore, this study tries to analyze the efficiency of lemna and azolla powders in removing hexavalent chromium from aqueous solutions. Methods: As an experimental trial, this study was conducted experimentally in the lab scale. Initia...

This research aims to determine the nutritional content and best treatment for addition of Lemna sp. fermented growth sangkuriang catfish. The was conducted from February August 2022, in Aquaculture Laboratory Fisheries Marine Science Faculty, Universitas Padjadjaran. method used this is experimental, a Completely Randomized Design (CRD). It consists four treatments repetitions, namely A (contr...

To provide information upon the ways in which Lemna paucicostata uses the methyl group of methionine, plants were grown for various periods (from 1 minute to 6.8 days) in the presence of a tracer dose of radioactive methyl-labeled methionine. Protein methionine accounted for approximately 19% of the accumulated methyl moieties; other methylated products, about 81%. The latter group included (pe...

El presente trabajo de investigación, tiene por objetivo evaluar la fitorremediación del ión cobre mediante especie lenteja agua (Lemna minor) en aguas residuales mineras; para ello, se preparó el con iones a una concentración 4,780 ppm; teniendo como referencia descarga un efluente mineras, tejido vegetal estuvo varias semanas contacto cobre, solución nutritiva Lemna minor, llevó cabo planta y...

Background; Recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. Therefore, the aim of this study was to determine the feasibility of using Lemna minor for Acid Blue 292 (AB292) dye removal from aqueous solution and to determine the optimal conditions. Methods; This experimen...

The response of duckweed (Lemna minor L.) to salinity and osmotic stress was evaluated by monitoring growth and peroxidase activity every second day, for a period of 17 days. The nutrient medium was supplemented with isoosmolar concentrations of NaCl and mannitol (50 mM and 100 mM NaCl, 100 mM and 200 mM mannitol). Growth decreased markedly with increasing concentrations of NaCl and mannitol. T...

Textile industry processes are among the most environmentally unfriendly industrial processes; because, they produce color wastewater that is heavily polluted the environment. Therefore, textile industry wastewater has to be treated before being discharged into the environment. In this study, experiments were conducted for different process parameters like nutrient dosage and dilution ratio aga...

Adenosine 5'-phosphosulfate (APS) sulfotransferase and APS reductase have been described as key enzymes of assimilatory sulfate reduction of plants catalyzing the reduction of APS to bound and free sulfite, respectively. APS sulfotransferase was purified to homogeneity from Lemna minor and compared with APS reductase previously obtained by functional complementation of a mutant strain of Escher...
