Titration of Isolated Cell Walls of Lemna minor L.
A theoretical model has been built to bypass the equation of titration of the cell wall. This equation, which is an extension of the Henderson-Hasselbach equation, underlines the importance of the exchange constant, the ionic strength as well as the rate of neutralization. The model is restricted to the case when the ionization degree is equal to the neutralization degree. The shape of the titr...
متن کاملExchange Properties of Isolated Cell Walls of Lemna minor L.
From our theoretical treatment which is an extension of the classical Donnan theory, we have estimated the rational selectivity coefficients of the carboxylic groups of the walls during exchanges of divalent ions against monovalent ones (i.e. calcium and potassium or calcium and sodium ions). These coefficients express the interactions between the different ions, those between the counter-ions ...
متن کاملGrowth response of Lemna minor L. to paracetamol
Surface water and groundwater is contaminated with pseudoperistent xenobiotics present in the environment. The risk associated with an increase in the consumption of drugs and their permanent occurrence especially in the aquatic environment falls on non-target organisms. The aim of this thesis was to assess the effect of increasing concentrations of paracetamol (0.1; 10; 100 μg/l) on the growth...
متن کاملAmino Acid Metabolism of Lemna minor L . 1 III
Aminooxyacetate, a known inhibitor of transaminase reactions and glycine decarboxylase, promotes rapid depletion of the free pools of serine and aspartate in nitrate grown Lemna minor L. This compound markedly inhibits the methionine sulfoximine-induced accumulation of free ammonium ions and greatly restricts the methionine sulfoximine-induced depletion of amino acids such as glutamate, alanine...
متن کاملShort communication: algae of Lemna minor L. growing in natural habitat and aquarium
In this study, the epiphytic algae of Lemna minor collected from its natural habitat or grown in aquarium were analyzed for a period of six months from April 2016 to September 2016. While a total of 15 taxa, 1 belonging to Cyanophyta and 14 belonging to Bacillariophyta, were recorded for L. minor grown in aquarium, a total of 36 taxa, 3 belonging to Cyanophyta, 5 belonging to Chlorophyta, 1 bel...
