  1. The 'whole-effluent' toxicity approach

    International Journal of Environment and Pollution 31(1-2):3 (2007)

    The identification and quantification of effluent toxicity plays an important role in the evaluation of harmful impacts on the aquatic environment. The aim of this study was to demonstrate the advantages of using the 'whole-effluent' toxicity approach compared to prediction of toxicity using key toxi...
  2. A biomonitoring study: trace metals in seagrass, algae and molluscs in a marine reference ecosystem (Southern Tyrrhenian Sea)

    International Journal of Environment and Pollution 29(1-3):308 (2007)

    Marine organisms were tested as possible biomonitors of heavy metal contamination in Ustica (island of the Southern Tyrrhenian Sea). The concentrations of Cd, Cr, Cu, Pb and Zn were measured in the phanerogam Posidonia oceanica L. Delile, the two brown algae Padina pavonica (L.) Thivy and Cystoseira...
  3. Algae as biomarkers, bioaccumulators and toxin producers

    International Journal of Environment and Pollution 13(1-6):92 (2000)

    Uncontrolled accumulation of wastes in marine environments involves an increase in organic substances and/or nutrients, as well as toxicity. The consequences of this enrichment for the homeostasis of ecosystems are unpredictable. The best studied consequence of such enrichment is eutrophication (Cont...
  4. Effects of electrolysis stress on the growth of Microcystis aeruginosa

    International Journal of Environment and Pollution 37(2-3):339 (2009)

    As a result of electrolysis, biomass was controlled to some extent and the protein content per gram wet algae decreased. The viability of the algae was measured by the flow cytometry. Without taking into account the consumption of substrate, Microcystis aeruginosa growth kinetics was demonstrated tha...
  5. Biosorptive separation of 'labile' fractions of copper and lead from river sediments and evaluation by differential pulse, anodic stripping ...

    International Journal of Environment and Pollution 27(1-3):179 (2006)

    The 'labile' copper and lead metal contents of contaminated sediments were extracted in different chemical solutions and then subjected for biosorptive separations. The sorbents called 'AlgaSORB-sp' and 'AlgaSORB-ch' were derived from two different algae, viz., Spirogyra and Chlorella, respectively ....
  6. [Action of different types of vegetable hormones on the growth of microalgae]. FAU - Fernandez-Valiente, E

    Microbiologia espanola 30-31:1 (1977) PMID 548698

  7. Sustainability assessment of microalgal biodiesel production processes: an exergetic analysis approach with Aspen Plus

    International Journal of Exergy 10(4):400 (2012)

    Biodiesel production growth rate keeps increasing every year with the hope of replacing fossil based liquid fuel which is near exhaustion. Energy efficiency methods coupled with environmental and economic sustainabilities would render biodiesel production attractive. Algal cultivation and oil extract...
  8. The role of microalgae in the deployment of biofuels: contrasting algae and solar technologies

    International Journal of Technology, Policy and... 12(2-3):158 (2012)

    With this study, it is aimed to provide an integrated review of the likelihood of microalgae deployment in the framework of biofuels production, while confronting it with emerging technologies, namely solar power. In this framework, a comparison study between the evolution of solar energy and algae b...
  9. On biologically produced nanomaterials

    International Journal of Nanotechnology 3(2-3):236 (2006)

    Living organisms produce a wide variety of nano-sized materials or nano-structured materials to preserve their species on the planet. As Biologically Produced Nano Materials (BPNM) form according to the genetic information obtained in the process of their evolution, its shape or composition is well s...
  10. Anticoagulant-antithrombin and fibrinolytic actions of extract of marine alga Corallina rubens L. FAU - Guven, K C

    Haemostasis 2(6):260 (1973) PMID 4802400
