Cultured Catharanthus roseus cells exhibit transmembrane ferricyanide reduction through a plasma membrane redox system which may be associated with proton translocation. Evidence shows that endogenous pyridine nucleotides serve as hydrogen donors for the reaction. The proton translocating function of the redox system is confirmed, in intact cells and(More)
Effects of light and temperature, on the growth of three freshwater green algae isolated from an eutrophic lake and identified as Selenastrum minutum, Coelastrum microporum f. astroidea and Cosmarium subprotumidumwere studied in batch cultures under non-nutrient limited conditions. Experiments were performed to determine the growth rate over a wide range of(More)
Heavy metals (Zn and Cd) effect and their bioaccumulation by a microalga Micractinium pusillum were investigated. Results showed that Cd was more toxic than Zn on Micractinium pusillum. Indeed, inhibitory concentrations of 50% of alga population in 72h (IC(50,72h)) were 0.28 and 0.34 mg l(-1) respectively for Cd and Zn. On the other hand, metal extracted(More)
Removal of heavy metals (Zn, Cu, Pb, Cd and Cr) by an integrated wastewater treatment system, Two Phase Anaerobic Reactor (RAP) - High Rate Algal Pond (HRAP), was investigated. Results indicate a good reduction of these micro-pollutants by this system. Global elimination rates of treatment system are 80%, 87%, 38%, 60% and 63%, respectively for Zn, Cu, Pb,(More)
Cultured Catharanthus roseus cells exhibit transmembrane ferricyanide (FIC) reduction which is associated with a proton translocation and a decrease in the ATP content of the cells. The H+ efflux and the ATP consumption may be counteracted by vanadate, a specific inhibitor of the ATPase activity, and by Na2WO4 which prevents FIC reduction. From these data(More)
