  1. 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...
  2. Toxicity of substituted anilines to Pseudokirchneriella subcapitata and quantitative structure-activity relationship analysis for polar narc...

    Environmental Toxicology and Chemistry 26(6):1158 (2007) PMID 17571680

    This study evaluated the toxic effects of substituted anilines on Pseudokirchneriella subcapitata with the use of a closed algal toxicity testing technique with no headspace. Two response endpoints (i.e., dissolved oxygen production [DO] and algal growth rate) were used to evaluate the toxicity of a...
  3. Algal Genomics: Exploring the Imprint of Endosymbiosis

    Current Biology 16(24):0 (2006) PMID 17174910

    The nuclear genomes of photosynthetic eukaryotes are littered with genes derived from the cyanobacterial progenitor of modern-day plastids. A genomic analysis of Cyanophora paradoxa - a deeply diverged unicellular alga - suggests that the abundance and functional diversity of nucleus-encoded genes o...
  4. Environmental risk assessment for the polycyclic musks, AHTN and HHCB. II. Effect assessment and risk characterisation.

    Toxicology Letters 111(1-2):81 (1999) PMID 10630704

    These results lead to Predicted No Effect Concentrations (PNEC) of 3.5 microg/l (AHTN) and 6.8 microg/l (HHCB) for aquatic organisms. For the soil compartment, 8-week studies with earthworms (Eisenia fetida) resulted in NOECs of 105 (AHTN) and 45 mg/kg (HHCB) and 4-week studies with springtails (Fol...
  5. Diversity and abundance of Bolidophyceae (Heterokonta) in two oceanic regions.

    Applied and Environmental Microbiology 65(10):4528 (1999) PMID 10508085

    The diversity and abundance of the Bolidophyceae (Heterokonta), a newly described picoplanktonic algal class which is a sister group to the diatoms, was assessed in the equatorial Pacific Ocean and in the Mediterranean Sea by culture isolation, molecular biology techniques, and pigment analyses. Eig...
  6. Regulations for combined effects of pollutants: consequences from risk assessment in aquatic toxicology.

    Food and Chemical Toxicology 34(11-12):1155 (1996) PMID 9119330

    In the analysis of combined effects two reference concepts are currently considered as equally valid for the assessment of mixture toxicities: these are LOEWE additivity (concentration addition) and BLISS independence (response addition) (Greco et al., 1995). The aim of this study of 137 binary mixt...

  8. [On hydration-related development and drying resistance of Cyanophyceae].

    Archives of Microbiology 44:189 (1962) PMID 13954238

  9. [The effect of industrial waste waters on socalled demonstration of plankton].

    Deutsche Zeitschrift fur die gesamte gerichtlic... 51:409 (1961) PMID 13789573

  10. [Vitamin B12 content and vitamin E content of the unicellular green algae Scenedesmus obliquus].

    Zeitschrift fur Naturforschung. Teil B. Anorgan... 13B(9):605 (1958) PMID 13604674
